[@208bowmaddnneess]

What a wealth of knowledge! Thank you Speedy and Erik. I’m excited to test forward of this (touching) in a few barrels. As a hunter I won’t do a hard jam just because of the risks involved but going in like Speedy suggests that .006-.009 is definitely worth it. Doing this along with your tuner should be money

[@DadWil]

I tried this method recently with a slight modification. to avoid having to remove the barrel I hung the case on a 12" piece of 8lb mono-filament and dropped it in the chamber. works great.

[@kenjaworski6237]

I used 50# braided fishing line with the primer removed. When the cartidge released from the rifle there was zero and I mean zero stickiness. And I thought I was the only one to think of this!!

I can get good groups seating long at, or just off, the lands. But I usually have to single feed to do that... I got tired of single feeding and decided to experiment with mag length. My best groups with that rifle came from jumping .182" Sometimes you just never know until you try.

Thanks for your work here on You Tube Erik. I just practice reloading for hunting purposes. I have a Winchester 70 in .264 Win Mag for “long” range shots and I’m planning to buy a Winchester semi in 30-06 for boar hunting. When I started I saw several videos, maybe 100. I founded good contents but also something that was totally anti-scientific and leading toward unconsistent practices. Then algoritm fortunately suggested “precision reloading its easy, you complicate it”, and then “stop chasing the lands”. I am happy for my subscription here, you produce great content. Sorry for my bad english and thank you again.

[@tim1942]

Could listen to him all day Thks

[@ewathoughts8476]

That is what in the 1960s we called finding the PLUNK length. Finding PLUNK and working forward, or finding JAM and working rearwards is the same idea. Finding PLUNK is easy without removing the barrel. Just clamp the rifle vertically and drop the dummy round in the chamber, and lift it with a light weigh wooden dowel. It is very easy to feel when the bullet is not sticking. I usually find the best precision using a freebore type chamber somewhere between JAM and PLUNK, but not always. Often does not work on Mauser pattern throats where there is no tight freebore to help align the bullet to the bore.

[@Michael-rg7mx]

What confuses me is the order to do things. You need to shoot a hundred through it before testing for the seating depth, right? Then to look for powder charge weight you need to have done seating depth testing first, right? It's a pressure nightmare to work up a maximum charge weight then start going from a jump to a jam.

[@mikeruppert501]

Couple thoughts-you can map lands on a new barrel too, start with your accuracy load and seat deeper to look for better accuracy, and make sure you’re safely below max before testing longer rounds since pressure could get higher.

[@ibanezrg320fm]

@@Michael-rg7mx Shoulder Bump first, powder ladder load second looking for best group, then seating depth.

[@Michael-rg7mx]

@@ibanezrg320fm If the first step is sizing a fired case the real first step is fireforming, right? I guess that would break in the new barrel too?

[@ibanezrg320fm]

@@Michael-rg7mx Yes sir! It kind of sucks that you should fire form first because you end up wasting the powder and bullet to be able to shoulder bump. What I do anyways is treat every single round as a test. ¹ Say I bought brand new never fired empty brass. Obviously I can't shoulder bump it because it is or should be SAAMI minimum specifications brass. So okay, I can make a test from this! You can at least make a ladder load test to see the accuracy that brand new brass will give you. And after your test if you see a node that does quite well, you could hand load the remaining brass and mess with bullet seating depth. This would be its own singular test because once you fireform that brass, you will introduce a new variable (space/air) and that will change the pressure. ²Once you have fireformed brass, you might as well start your test over because if the base of the case to the shoulder grows, it's a new variable that impact powder charge. If you think about it, seating depth will not change but since your shoulder is now further away from when it was new, you're introducing more internal case capacity, ie air. Not very much but trust me, it will affect your velocity. Depending on your rifles chamber dimensions, it is possible you might have to shoot that brass a couple times for it to fully form to your chamber. I learned all of this with my M1A. I did a test of first finding out what a load would do with new never fired brass. I load up a ladder load first to test what charge would cycle the bolt. Once I found the minimum amount of power to make this rifle cycle properly, I made that my starting powder charge. I shot all of those rounds to fire form the cases and next I intended to bump the shoulder back 2 thousandths but here's the thing I didn't know. The M1A is a battle rifle and so they made the chamber a little longer so that almost any sized case of the same cartridge would fit and fire because in war, you need that rifle to function so you don't get killed. Once fired brass does not fireform to the chamber. It took me 4-5 firings for that brass to finally stretch far enough that I could bump the shoulder back! So once I figured this out, I did a little test between minimum charge on new brass versus 5 times fired minimum charge brass. The result was +200fps!!! The only difference I made was shoulder bumping. Bullets remained the same, powder and charge remained the same, but base of the case to shoulder measurement was different. I introduced a large case capacity. Even though cartridge overall length remained the same, the fire forming and brass stretched at the shoulder increased x-amount of room that wasn't there before in new brass. It was a fun experiment to see what my velocity would do with new brass versus shoulder bumping and what a difference it made to my velocity! So that's why I say you will have to redo your powder charge on fire formed brass because that introduction of air changes the pressure which changes your velocity. However, you should pay attention to what the velocity is of new brass versus shoulder bumped. If say you found an accuracy node at 2700fps, it might be possible to find a new charge with shoulder bumped brass to get you 2700fps and remain a tack driver at that specific velocity. Not everyone is loading for a battle rifle like I am so it probably won't take you more than 1 or 2 firings. I use the same methods for my home built AR-15 chambered in 300 Blackout but that chamber is cut just a little more than SAAMI and only takes 1 or 2 firings.

[@savage1030]

I sure do enjoy him talking. Speedy and Jack content is the best your channel has put out.

[@benny1235]

I think a step that is commonly overlooked in finding seating depth has to do with chamber cleaning. I'd think there would be some debris in there that could throw your numbers off a bit. I will normally spin a chamber brush in my drill with my favorite bore cleaning solution. After doing this and running dry patches I'll run a couple of patches with an alcohol or acetone. Then blow out with compressed air. It is best to have a clean bore as well when blowing air into the chamber.

[@mckimmym]

Erik cleans down to bare metal, every time, no matter what. ;)

[@joesquid6988]

always great watching a master show. If we are not able to pull the barrel, what do you recommend? I've used the Hornady tool, I've used the rod down the barrel to the bolt-face, then insert a bullet to jam, run the bolt down till it touches the bullet and measure the delta. From either, I then go with the bolt drop - that becomes my kiss point. In my BR days, I then worked into the lands (always a sweetspot at about 0.012" into the lands from kiss). Now days, I simply back off 0.020" and begin working back from there.

[@tonydevich7937]

Thanks speedy for the info

[@jimabel7458]

Very interesting and informative. I remember when the had the partially seat a bullet and use a lighter or match to blacken your bullet. Seating the bullet deeper until the land don’t disturb the coating. This then gave you a coal for reference to not exceed.

[@greasemonkeyviking384]

Such a cool dude!

[@jessewerner4067]

This is the same method I use and probably the most accurate. You don't have to pull the barrel to do this though. Use your pinky finger to shove the dummy round into the chamber against the shoulder and a cleaning rod from the muzzle. You can actually alternate pressure between your finger and cleaning rod to get a better feel for the "stick" of the bullet this way.

[@ghostofcpast8893]

100% agree. I tested 18 /3 shot groups with Berger bullets and ALL my shots were within a .628 group. Some like being jumped .125" . I think accurately recording it when it's loaded is the important part

[@torreyintahoe]

That's good advice! I was just thinking, this is cool but I'm not taking off my barrel.

[@davidunderwood3605]

This is something I thought most did before ever installing their barrel. I do but I've never used a resized case with the adjusted shoulder bump, but will now. I've just always used a factory new case.

[@speedygonzalez_x_files]

We start our load development and this test after 50 to 60 rounds have been put through the barrel. That's the reason we must remove the barrel to establish the new touch ZERO.

[@tonystewart7287]

Very interesting thanks 😎😎

[@joeldubose5762]

I've always use the Alex Wheeler method. I have a drop port, so I don't have an ejection pin. , I remove the firing pin, then close the bolt on a sized case. With the bullet long, I move it in just like you are here and try to close the bolt. When I get close, I slow down how far I move the bullet in until the bolt falls by itself without drag. .001 touching, and you can feel the bolt drag on closing.

[@richardfitzsimmons5244]

Ive heard of the PRS guys reaming out their chambers for a lot of jump. Scott S. Talks about it in one of His videos. I don't know if it's a Weatherby philosophy or why. But obviously it works for some .

Trade secrets almost……cept twinxt really good friends and possibly 98k or so subscribers…….Speedy- great to see some of your work get out to the faithful! What I wouldn’t give to spend a couple of weeks at his shop! I could possibly understand part of the information?

[@mckimmym]

I was rummaging through my grandpas shop over thanksgiving and found a RCBS precision mic for our 7 rem mag. How do you feel about that tool? I got inconsistent readings with it using the scale on the side, however I also mic’d it with a Hornady bullet comparator and three measurements were all within .002 of each other 🤷

[@markroper9269]

Love the video!

[@johnnash5118]

The “sticking” comes from the Leade Taper of the throat, the last section of the throat that transitions from no rifling (the Freebore) to full rifling (the Bore.) The beginning of rifling isn’t abrupt, it has a transition angle and length that varies with each barrel. So different bullet ogives will seat differently as well according to their own angles. Imho, barrel removal isn’t needed because releasing the bullet in the Leade by touch is the same as using gravity by gently inverting the whole rifle.

[@jorgefigueroa7573]

Excellent video and Erik pointed out something that I rarely hear others talk about, is a long jump. And speedy called it, like shooting factory. Erik mentions the PRS shooters that talk about a long jump. In my opinion PRS shooters have the choice but will always shoot from a Magazine Vs single fed cartridges. So one has to basically has to work with the Magazine allowable length. Now with that said. From my personal experiance. I shoot a PRS style rifle but recently tried FTR. So I'm single feeding my cartridges. And I have tried Jam, touch, and jump. with the Particular bullet my rifle seems to really like. And surprisingly my rifle likes jump. So much that my jump is 207 thousands off jam. And what I use as Jam, is the rifling grabs the bullet period. Meaning you have to run a cleaning rod to tap the bullet out. I do have a custom barrel and chamber. Its a Palmer chamber. Now I maybe saying this incorrectly but the reamer is designed to make a parallel throat before the Lands VS Funnel shape like what you may find on Factory chambers. That allows one to have a long jump VS jam or touch. And still show the same result. Now I'm no expert on the definition of a parallel throat. But the word parallel is what has been explained. Now as far as the results on paper at 100 yards, they are 1/4 or less, mostly less. And when I have tried Jam or touch, the barrels just does not like it and I get pressure signs and sticky cases or I have to use a rubber mallet to tap back the bolt because of the pressure. And that is using the same powder load and bullet as I use when I'm way off the Lands. This is how it works for me so far.

[@BTOMF]

This is an excellent observation. I might add to your comment as well that Erik pointed out that the testing Mark Gordon did with jumping in that .080" range was "the best place to be." I think what his and Scott Satterlee's testing shows is it is the most durable place to be. Good accuracy and durability. Their testing did show that being close to the lands gave the tightest groupings, but wasn't as forgiving or as durable as jumping that far off. And I like Speedy's answer to the question which makes sense considering his application.

[@jackwilliams7688]

[@davidross1882]

Now that’s a slick way of finding your seating depth !

[@372HGS]

Erik, I learned that when the firing pin makes contact with the primer, 0.003 of jump is lost when the case is forced deeper into the chamber. I believe this is a discovery of Litz. What are your thoughts on this? 0.080 to 0.100 of jump is common in factory Remington 700s loaded to max COAL. I had a 308 that was jumping that far and was still shooting well for what it was.

[@billcarlson852]

Speedy(Tom)will not remember Julio, but we met @ I believe the 2001? FISS @ Kelby's range in N. Lawrence Ohio. I was on the #1 bench on maybe the 2nd round of the 100-yd competition. I had 4 in a bug hole, (potential world record .005-.006") and I threw the 5th out, one bullet hole. Went from hero to zero in one 1.5-ounce trigger touch. Unbeknownst to me, the likes of Walt Berger, Tony and Faye Boyer, Fred Hase Custer and Mr. Dowling, along with Speedy were standin behind me, waiting for the last sear break. I knew before I returned rifle to battery by the moans from that small, yet very well-tuned crowd behind me, that all was lost...OH, I think that Jim Carstensen may have been there as well. This was the first BR rifle I had ever had and was purchased from Jim, as he had won the LV Agg @ the 97 FISS with it. He COMPLETELY took me and a buddy of mine up under his wing, and for the next couple seasons, GLADLY showed us the ropes. NOTHING BUT the FINEST folks in this sport; NO OTHER SPORT COMPARES, in my book. Sincere thanks to you, Speedy, for the knowledge you freely bestowed upon us in your years. A legend and friend. We were both younger then, and much easier to look @ !!! Tight groups

[@billclifton8400]

So the way I've always done it is I use the gauge and jam the bullet then just shorten the stony point gauge setting about 10-15 thou and then 3 thou at a time and push it in with the bullet and keep doing that until the bullet doesn't stick. I use a wooded dowel to keep tapping the bullet out until I can push the case and bullet in without the bullet sticking. Can usually find it within a few tries because it always seems to be close to 20 thou back from where I first jam the bullet by pushing it into the rifling. I like to make my own modified case from a case fired in my chamber. It requires fiddling with the set screw on the stoney point gauge and measuring each time so it takes a bit of time but don't have to pull the barrel. I guess just different ways of skinning the same cat.

[@sxsboy2253]

How much would you reduce the powder charge when seating into the rifling if I’m jumping a 208gr .308 hornady bullet .015” in my 30-338 that is loaded to what I’m considering the top of my guns pressure acceptance. The barrel is a Krieger .3078”, 1-10”. Currently it shoots into the low .400’s but I think I can get more out of it. BTW did you used to be called Speedy Gonzales? Thanks for the informative video.

[@drfroglegs]

Could you use a depth gauge? Measure the empty case, then measure the case with the bullet and calculate how much the long case is longer than the empty case... That would tell you how far the bullet is keeping the empty case off the chamber.

[@jcnikoley]

I’m loading for a SA so I’m restricted by magazine dimensions, but I seat out as far as I can, then drop the round into the chamber, apply light finger pressure, then turn the barrel up and make sure the round drops out freely. If it sticks, I’ll keep seating deeper until it drops free. TL/DR: I do the same thing. 👍

[@oif3vetk9]

SA, semiauto? In my opinion with gas guns, seat at factory C.O.L. and let the EC tuner/brake work the rest out. I load 6 ARC and I set everything to hornady case specs for sizing and seat the berger 105 hybrids at factory C.O.L. then tuned it. On a AR platform I just think it's the best way to do it. (Just my opinion, I could be wrong.) Gas guns are absolutely a different world to load for compared to bolt. lol

[@jcnikoley]

@@oif3vetk9 I’m also shooting/reloading for a 6 ARC. Great minds think alike? I usually stick with published COAL but always check to make sure the bullet isn’t getting jammed. A lot of people have reported sticking their bullets in the barrel with factory ammo in 6ARC, it’s just something I check. I’ve always done it this way reloading for other calibers as well, bolt or gas gun I don’t want my bullets getting jammed in the rifling. I’ve been doing it this way for about 40 years. I didn’t know it was something new.

The problem that I have with this method is that the ogive differs when you change projectiles. How many times are you going to remove the barrel? I use an empty case with loose seating and chamber it with the bolt 3 times to get my DTL

[@MMBRM]

Thanks for another informative video. I'm curious about speedy's policy about how much bearing surface he wants in the neck for his benchrest guns. I'm more interested in the minimum amount. I've noticed inconsistency when I go below a certain number which I attribute to inconsistent ignition due to lack of "neck tension". On a side note I've recently been testing some longer jumps(.050-.070 off jam) to get the necessary bearing surface in the neck with certain bullets(availability being what it is) and the results have been surprisingly good.

[@speedygonzalez_x_files]

Powder, Neck Tension, & Bullet Seating depth is the Holy Trinity of accuracy. The knowledge of how those three relate and effect the performance of the firearms is the key to the marriage of accuracy and precision. To answer you question the more the bullets is into the neck the less tension is required. I seat my bullets about 1/3 to 1/2 into the length neck, to get consistent performance I must increase my neck tension to about .0035 to .004 compared to .001 to .002 when using almost the entire length of the neck.

[@johnnymissfire8464]

@@speedygonzalez_x_files I find that amazing that you have that much of the bearing surface out of the case neck. That is awesome of you to share your knowledge, thank you!

[@MMBRM]

@@speedygonzalez_x_files Thanks a lot for the detailed reply. I also had to modify my neck tension used when I started annealing every firing. I began getting fliers when using the 0.001-0.0015" that I had been previously using. I changed it to 0.003" and they went away. Neck tension is so much more complicated than just the amount the brass is expanded when the bullet is seated. I'll try even more neck tension to see if I can negate the inconsistency I was getting when the bearing surface was less than 0.140" into the neck of my 6PPC. I found that it was better to jump the bullet even 50 to 80 thou off of jam than to have not enough bearing surface in my current methods. Thanks for sharing!

[@trikelife4960]

Thank you for asking this and thank you to Speedy for the detailed answer. I have some testing to do now lol.

[@davecollins6113]

Certainly found it easier to run cast bulletts jammed or even fully breech seated to get a load to shoot, than backing it out. I have one gun I'd be willing to experiment with touch or jamming bullets, seeing as it isn't a hunting gun. One of these days I'll get a roundtoit. it's the unknown of pressure difference to get the bullet moving in the bore that spooks people, maybe can't run max velocity that way. Primer pocket life will dictate that.

Easiest way to do it with a barreled action, rifle in a cleaning cradle, place round into chamber. Tap round with your finger tip putting the round as far as it will go in the chamber. Tilt rifle if you are not into the lands the cartridge will slide out. If it sticks you are in the lands, tap out with a cleaning rod.

Interesting video. Have you run a comparison between this and the Hornady OAL gauge? Is one more repeatable than the other? Are their measurements the same / similar (with a fired / modified case of course)?

[@claverton]

Personally I think the Hornady OAL gauge is a total waste of money. I put a loosely fitted bullet into a case and load it into the rifle chamber with a tiny bit of loctite on the inside of the neck and leave it in the chamber for half and hour to let the loctite stick, and presto, you have your case with bullet on the lands ready to measure. What could be simpler?

Hi erik im still learning and was wondering if its common to seat bullets out more then .080 of manufacturers suggested seating depth. Also does that change velcities when you seat the bullet farther out

[@post_historic]

Seems that the deeper you seat, the more the case pressure increases. Many claim that going for max velocity will not yield greater precision (more turbulence and probably takes longer to stabilize). In competition you're not trying to knock somthing down just get it where it needs to be!

I use the hornady, I would have liked to see what the difference was.

I know this is an old thread but the last thing you said sounded a lot like if you load a weatherby cartridge into the lands it would automatically be over pressured. Is this true or dangerous?

[@garyomalley4521]

I like Eric because he doesn’t add “hydraulic hubcaps” to his procedures. I’ve seen fantastic consistency from factory ammo. I don’t get it when some on KZbin snicker at factory ammo. One lot of ammo might be bad for rifle “A” and be great for rifle “B” too in both SD and precision.

Not sure if this can be answered. I have built a new 6 GT and all I have is new cases, none that have that have been fired. Will this method work with a new case rather than a resized?

[@diamon4u]

You have to start some somewhere. Pick a load close to the top with your powder and bullet at an arbitrary length let’s say from a custom reloader data. Shoot and get 25 fire formed pieces of brass. Now determine your hard jam and back off .020. Do your powder charge first 3 shot groups and find a node with 3 good groups -not perfect, but good. Choose the charge in the middle of the 3 good groups and do your seating test moving bullet deeper in .003 increments. :-)

With this method or the hornady OAL gage, what is important is to use some cases with the right headspace measurement. Not with the 0.002' bump, but the exact chamber fit ; otherwise it wont correspond with what happens when you're closing the bolt.

[@ErikCortina]

Aren’t you gonna close the bolt on brass that has 0.002” bump?

[@kybowhunter1974]

Why won’t it either the ejection plunger or firing pin seats the shoulder of the case against the chamber shoulder when fired. So no matter what happens behind the dantum the jump, touch, or jam will always be exactly the same.

[@br4713]

@@ErikCortina If you have no ejector and you wanna seat your bullets into the lands (reloading for benchrest shooting), there's a problem with this measurement method. Because without ejector pin the case isn't pushed against the front of the chamber, so there's some play in front of the shoulder. If you take the measurements with this method and you use a case sized to fit exactly your chamber length (instead a 0.002' shoulder bump), the measurements will be exact for any situation.

What is the name of the vice being used in the video?

[@noellewis6358]

What if there is runout with the projectile???

[@762longrange]

What bullet comparator set gauges ?

[@oldmanSturzl]

Who makes the arbor press you're using?

[@leonhorn8062]

I prever the way Eric did it in a previos video. It males more sense to have only one direction to move and it seems easier

[@br4713]

Many people complain about the hornady OAL gage but for me it's easy, fast and accurate. If you get inconsistent measurements it's just because you dont use it the right way (pushing the bullet too hard against the lands). Most people dont want to remove their barrel each time they wanna try a new kind of bullets.

[@308ranger8]

I use Hornady as well and it gets you close enough but these guys are professionals so i can understand why they do it this way
