My method is actually the last one that Travis showed. The one where you let the lands push bullet in. But it is neck tension dependent. I also put die wax in bullet ogive to prevent it from sticking in the lands. The method of seating bullet deeper and deeper until bolt closes is the Alex Wheeler method. As you said, there are a tons of ways to measure this. Multiple ways to remove outer layer from feline. 😁

Not a comment for Erik (he clearly knows what he is doing), but a comment on his process. I suspect the benefits of either the second (loctite) or third (Erik Cortina... or similar Alex Wheeler method) is consistency/repeatability in that in the second and third, it is a combination of the camming action of the bolt plus whatever you neck tension is. If you are good at consistent neck tension, then you should get repeatable results. For the first, when using the rod to push the bullet in, that level of force is variable from one person to another and maybe even from one test to another from the same person. I personally use the Alex Wheeler method and have found it to be very repeatable while the rod method is not. The downside of the Wheeler method is you have to do things like remove the extractor, etc. from the bolt because the ONLY force you want to feel is that of the bullet touching, barely touching or not touching the lands as you close the bolt (and not compressing an extractor spring for example). It also requires a bolt that closes easily/smoothly. Lastly, I can imagine using the bolt to seat the bullet vs. the Alex Wheeler method maybe creating different measurements because using the bolt to seat the bullet, is pushing you slightly into the lands, while the Wheeler method may allow you to measure where the lands are just touching. I should probably give Erik's method a try as it might be easier to do in the long run.

Regarding the locktite method. I always pop the primer out. This allows air to escape out of the back of the case when the bullet is seated in the lands. Stops loctite from seeping out of the case neck into the chamber of the rifle.

I started reloading in the early 60’s before oal comparators, with all my knowledge coming from reloading books and magazines, totally absorbed into shooting and reloading. Early on, I started trying multiple methods, some discussed here, but I found that if you just took whatever bullet you were going to use, drop it down the bore and just tap it lightly to jam the lands, I took a wooden dowel, advanced down the muzzle till it touched the bullet, then make a mark on the dowel with a sharp pencil at muzzle, then push bullet out of the barrel with the dowel, remove bullet, close the bolt , push dowel till it is up against bolt face, then remove dowel. Measuring the distance with my trusty Craftsman dial caliper precisely gives me my max coal for that particular bullet. I would then and now, especially it seems with all Berger bullets, they do better with up to .080 of jump. This easy method has always worked for me. I would like to have one of those nice Delrin rods though. Would seem to be perfect to use for same method.

I’ve used a brass rod and two locking collars. You close the bolt and insert the rod to the bolt face and set a collar at the barrel end. Then insert a bullet and use a pencil or rod to hold pressure on the bullet from the action end. Insert the rod to the bullet tip and set another collar. Measure between them and you have your jam. But Eric’s method is much simpler.

When using the OAL gauge, try using this with the rifle in a vertical position. What this does by having the muzzle pointing upwards, you can lightly lift the bullet to the contact point and not jam the bullet into the lands. If your bullet is sticking into the lands, you really have no idea how deep that is going.

I’ve used the sharpie method for several decades, but bought hornady’s oal gauge 3-4 years back. I made my own dummy cases (fired in my chambers) and bored and tapped on my lathe. I use a hardwood dowel in conjunction with the gauge to push the bullet back and forth to get a good feel for the contact of the bullet and the lands.

I agree with Eriks method and have used it for some 40+ years, I do however use a modified version of that for super super exact loadings, What I do for those is I use my normal push back method and add to it by blackening the bullet with a sharpie or carbon black. I insert the test cartridge, close the bolt and note the land marks on the bullet after it has been pushed back. I then repeat 3 x and note the lengths....depending on the marks of the lands on the bullet will let u judge on whether or not your 3 bullets are seating on the lands consistently and with the same force. Always always always measure your length consistencies exactly like you showed in the video, using the apex of the bullet ogive. Beginning shooters might want to measure from the bullet tip but NEVER NEVER do it as tip profiles in the same batch of bullets can vary significantly, the ogive or slope profiles never changes at least in the same lot of bullets......Use a diffrent lot......start all over..... Just saying !!!!!!!

Thanks for the ongoing videos. Great stuff. I will say I have driven myself crazy trying to get consistent readings with the OAL gauge. (Especially true with VLD bullets.) TINY variances in pressure on the push rod change the distance to the lands a fair bit. It’s a hassle to remove the firing pin and ejector button (Wheeler method) or Barrel for the fingernail lift method (Mark Gordon method, explained in the Precision Rifle Blog), but I have found these methods very consistent.

Using the OAL gauge, you're pushing the bullet into the lands, whereas with the other methods, you're not. That is why you're seeing a difference. I've learned to use the gauge and NOT push so hard. Push until you meet resistance then release and then lock the push bar in place. I find that you will see the same kind of measurements as the locktite method.

That's why I want to find my O.A.L. with a fire formed case and resized with just enough neck tension to hold the projectile in place so I'm not jamming it into the lands, just touching. But at the same time I'm not putting to little neck tension so that when I hit it with calipers, it doesn't push the bullet inside the case. I do that 3 times and measure 3 times. If the measurements are the same or pretty close +/- .001 I know I'm good. If the measurements are off, then I know the neck tension is to tight because If the first measurement is 3.290" and the next is 3.330 that means the lands are grabbing the bullet....The bullet shape could be off that much BUT I doubt it.

I use a cleaning rod with a jag that's filed smooth at the end. On the rod, I placed two nylon bushings. With the bolt closed, I run the rod to the bolt face and the two bushings to the muzzle end. I then put a bullet in the chamber and push it forward until it touches the lands. Holding the bullet in place, I run the cleaning rod until it touches the tip of the bullet and position the second bushing closest to the muzzle against the muzzle end. Measure the length from the beginning of one bushing to end of second one. The OAL from the bolt face to the lands is the measured length minus the total length of the two bushings.

One issue with using the close the bolt method is that the seating depth might be increased by the pressure of the bolt. Furthermore, then when the bolt is retracted the bullet might ease out slightly from the case. It would seem the loktite method provides a good maintain of the bullet in the case. But I cringe at any red loktite in my chamber!

Very Good Information. I love the third method (that I have always used) since it requires no special devices or tools and it is easy IF you are shooting different weights, lengths and ogive geometry, Use a once-fired case, tension the neck ONLY and let the lands seat the bullet. Important that you are careful that the land tension does not pull the bullet out of seating during the extraction of the test cartridge. Perform this a few times and look for consistency.

Just starting to get into hand loading and it is easy to get lost in the weeds… This video is. very helpful. How do you approach initial cartridge length measurements for a new system? Imagine new rifle, brass, etc… for the initial firing of new brass, the recommended approach is to seat the bullets at the lands… I understand that it is critical to get a measurement from the bolt face to the lands which the gauge method cannot provide. The difference between the gauge measurement and the bolt methods implies extra headspace even on a fired case… it has been mentioned elsewhere that it can take more than a single firing for a case to fully expand to the chamber dimension and there should be some spring back expected as well. Keep up the great work!

Gavin I do two things. I use a fire formed case. Next I take out the firing pin and the extractor out of the bolt. Then I put the case and bolt in the gun. If the bolt does not fall closed freely closed I will bump the shoulder of the case .0005 how ever many times it takes until the bolt falls closed. When that part is done the most free clearance you will have with the case is .00045. Then I start the same prosses over with the bullet. I will start with a measurement using the Hornaday gauge. Then I put the case and bullet in the gun. If the bolt does not fall closed then I will seat the bullet by .002 to .003 at a time. You will know when your about perfect. The bolt will start to fall half way then 2/3. At this point I go to .0005 seating change. When the bolt falls closed you will never be more than .00045 off the lands for that bullet batch #. The only reason for doing this is to know that exact length the bullet ogive touches the lands. I've been shooting bench from 1968 to know. The truth of the matter is the way you showed it the video works the same as I've done. Now matter how you find the lands we all start seating bullets + or - from the measurement we both got from our method we used to find the node the gun shoots at. I will say one thing. I made a tool using a seating die plunge and a dial indicator and comp to check ogive to tip of bullet where the plunger sits. I then write this down and check any other bullet I choose. Using math any other bullet I use I will know where to seat the bullet to start making up a new load just off the lands. I love your work keep it up. I built my first rifle in 1978 22PPC. One other thing, the tool I made and the seating die I use for any give caliber I had reamers made to redo there inside where the bullet hit so they are exactly the same. Good luck Rick D.

For 40 years I have held an unloaded case above a candle to get a good sooty effect. Close the bolt gently, extract, and see if you are touching the lands, and by how much. Seat bullet slightly deeper and repeat the process. When the bolt closes easily and there is only the lightest mark of the lands, you know you are good to go to calculate further seating depth. This may be too inaccurate for the most exacting bench-rest shooters, but it gives me one-hole groups from my .222 Rem. I also prefer to headspace using the bolt rather than the shoulder of the cartridge.

I'm going to share this on my channel and I really appreciate you guys demonstrating the importance of OAL measuring and using such a visually descriptive method to show this. I'm learning more and more myself and I happen to be at this step, as the .300 PRC seems to be VERY finicky about Ammo. I'm realizing that using book load data was giving me 0.0945" of jump on the 212 grain ELD-X and 0.215" of jump on the 250 grain A-tips.

I learned to reload on the 6.5 prc and recently the 300 prc. the long jump is typical on magazine fed rounds. To get the bullets up to touchpoint, with the new longer bullets, they won't fit in the magazine. Fortunately there are some good nodes at long jumps. As the throat erodes you may have to adjust seating depth. The long bearing surfaces seem to keep these new long bullets lined up despite the long jump until engagement of the lands.

Sorry late to using You tube I was taught (1970) to use a, neck sized fire formed case, light seat of bullet, soot with candle (let cool). Then put five in one by one normal locking of the bolt (first locking lugs should be polished to give even pressure) then measure OAL of the five, and average them. Set the bullet seating depth accordingly. Depending on the quality of the rifle, one of the locking lugs will inevitably seat tighter so should be found and corrected before worrying about the lands effect on accuracy, as it will change the measured value. I liked the idea of using the Locktite though.

I use the seating die and a resized empty unprimed case. In increments bullet seating further out until it does not chamber and I get rifling/lands marks on the bullet or the opposite and seating further down until it does chamber and no marks are visible but this takes a number of new unmarked bullets. Then I back it off to my desired COL. As stated, bullet type makes a big difference and results are based on each bullet type. I don't get stuck bullets in the lands this way since the bullet is seated. I only do it to know my chamber size. I do not chase the lands like I used to. Some rifles do not like it close to the lands while others do so I shoot different COL loads until I find the "sweet" chamber spot or accuracy node and that sweet spot will change between types of bullets and over time throat erosion. I have a .223 chamber that absolutely hates bullets close to the lands for that short jump. It likes a long jump to hit its best accuracy. Same for a .22-250 chamber.

Awesome video. I wanted to save some money for projectiles and powder so I took a case and instead of a full resize I just gave it enough to hold on to the projectile. Not too tight, but not enough to pull out. Paint with a sharpie and push it in and lock it down. I ran it multiple times to verify the bullet wasn’t pulling back out as I have had that happen in early stages. But just like you guys said pick a method and stick with it because you can get varying numbers different ways. Biggest thjng is making sure when you bring the dummy round back out, the rifling hasn’t pulled the bullet out. Sharpy helps you see that!

Method number 4: Seat to the max length of your clip... unless you want to single load every bullet... which I don't want to do. Zero the micrometer on your Forster seating die (if you have one)... Set the max length of your cartridge(to your clip), then lock the lock ring down on your die and call it good! You can make a longer drop in bullet using the adjustment on your micrometer if you want to get closer to the lands and or you can buy a second Lee seating die for seating the longer rounds.

I use a partially sized case, I only size about 1/16 - 1/8 inch of the case mouth. This way the bullet slides into case a bit easier so the bullet is less apt to stick into the rifling. My cast bullet loads take a bit more care on the neck tension. I'll repeat this check several times to average out the measurement, then set a bullet a bit long then using a sharpie on the bullet and progressively seat deeper till I find a length to just mark the place that the bullet fully seals to the throat.

I’m confused. The OAL gauge is longer, so you’re not pushing as hard. Also, it makes sense the way it work to put the bullet against the lands as gently as possible. Seems this would be the best way to be honest as the bullet is set to just kiss the lands and nothing more. I think you might have read those numbers backwards.

You didn't cover why you remove firing pin from bolt even though you mentioned you would...please do so.... Also marking the bullet with black marker.... The land marks on the bullet are very difficult to distinguish.

A couple of decades ago when I was REALLY into making the best ammo I could, I used Sinclair’s comparator. It’s similar in that it uses the bullet in the chamber, take a measurement. Runs fired case in and take a measurement then subtract the part of the bullet that will be in the neck and measure the over all length. I would prefer to measure off of the olive but their option was full length, bullet seated. I really like that Loctite method for the shooting I do now. Thanks, Jeff

@jessewerner4067
@jessewerner4067 3 жыл бұрын
First thought, do yourself a favor and use the Accuracy One seating depth comparator. It measures between the case shoulder and bullet ogive. So much more precise and quicker than the CBTO method/tool. Saves you on the math too. Hornady OAL is great and is best if you use a fired case with the shoulder bumped .001" so it's sure to chamber smoothly and headspace off of the shoulder. If you don't size (ever so slightly) the body of the case could stop the shell from fully reaching the shoulder and thus giving false readings. You can use the Hornady virgin case for this but there will be some math and corrections needed to get accurate numbers. Case base to shoulder lengths on a fired case need to be noted so that corrections can be made to the base to shoulder length of the virgin case. This "difference" needs to either be added to or subtracted from the CBTO measurement you get to the lands with the virgin case. Again, works fine but there's math you have to be aware of. Throw a virgin, belted magnum case gauge in the mix and it will not get true readings, you can't. That's why it's best to use a fired, slightly sized case with this method. Here's the method I use now and have found to be the most precise and consistent: Use a fired, very slightly sized case and polish the outside with steel wool. I don't want it sticky in the chamber at all. Seat a bullet a little longer than it needs and lightly push the case into the chamber by finger. It should "stick" because the bullet is in the lands. You'll need a cleaning rod to push it back out. Now, seat your bullet in the die shorter until it will not stick anymore. You want to find the spot where it is not sticking but .001" longer will. When you go to push the cartridge out with the rod, it will come with no resistance. This is a true measurement of no jump nor jam. I can feel a difference in .0005" difference in seating on the cleaning rod when you get to the right spot.

My method is the last one shown right down to the sharpie or black soot to mark the projectile. Bullet brand and model gets written down in my note book along with OAL for ease of setting up seating die the next time I use that particular projectile. I use this for all of my rifles and all of my single shot handguns chambered in rifle calibers....very repeatable and easy to do without the need for additional tooling.

Minimizing jump/finding the lands is one of the more persistent myths (IMO). I was a full on adherent until reading an article back in 2016 that indicated that not all bullets, particularly the newer VLD/ELD designs, responded well to that approach and actually gave better results with more jump. Having acquired a megnetospeed to fine tune my 6.5/RPR loads (never really trusted my Chrony), I set up a test with my, to that point, most accurate load. The change I made was to set the COAL at the 'book' value in the loading manual using Hornady's ELD-M bullet. I then setup of 5 shot loads of incremental COAL increase/Decrease from that point of .001 changes until the COAL maxed out "at the Lands" limit I had previously established with a dummy round. What I found was that the RPR/ELD-M had a very specific 'range' that gave best SD/ES and accuracy and it was NOT anywhere close to the lands. It was a range of approx .003" around the book COAL which was astonishing to me have 'grown' up reloading for over 35 years at that point, believing that best accuracy was ALWAYS found seating the bullet out close to the lands. This did not change when my barrel went past its 'speed bump' that most go through around 300 rounds or so. Like any load customization, what your particular rifle likes is going to be very individual, so really anyone's 'best load' is pretty much an ancedotal one off for that rifle/component combination. But before anyone goes all in on the "get as close to the lands as you can" paradigm, test your rifle with a good chronogrpah like the Magnetospeed or Labradar and spend some time testing various COAL setups. You might be surprised by what you find. IMO - YMMV
