Some folks are passionate about their bushing dies and claim near zero runout, and say I am doing something wrong. I am happy to see you have the same results with bushing dies as I have. I now exclusively use Forster full length sizing dies for almost no concentricity runout.

@@BoltActionReloading While I'm still contemplating ordering up some SAC bushings, decided to experiment.

Are the Whidden bushings not machined in the same manner as SAC bushings? Looks like it also has a gradual/guided diameter before narrowing after the case mouth has entered the bushing.

More videos on the expander mandrel please.

[@yle8708]

On an unrelated reloading subject. I recently learned of a new method for reloading belted cases. From what I understand you take an over sized mandrel or expander ball and run it through the neck of a piece of new unfired brass. For example for a 308 diameter projectile you would run approximately a 338 diameter mandrel through it. Then you would begin to run the piece of brass into the resizing die in small increments. Between each progressive increment you attempt to chamber the brass in the intended rifle. Once the false shoulder/over expanded neck is sized far enough down the neck to allow the piece of brass to be chambered in the rifle you go ahead and load that piece of brass. Once fired in the intended rifle the piece of brass should essentially be fire formed to that chamber with minimal stretching/thinning above the belt. Of course the piece of brass is now only reliable in the single rifle and would not be totally reliable in austere environments. I hope that I have explained that well and was curious if you had any experience with this method, or how it would compare to other options such as the Larry Willis die. I was considering this practice with a 375 H&H I'm doing load development for. Thanks again for the great videos and knowledge you provide.

[@keith9737]

Sounds like fireforming to a new cartridge. Bench rest shooters make a false shoulder when converting brass. I recently tried this on some 308 brass that had been severely bumped back at the shoulder. 0.010 to 0.015 less than the fired brass. As a comparison, I also shot similar brass with the bullet loaded long (0.005 jam) and some control rounds with no special procedures. While the false shoulder did give improved results over the control, the bullet jam method was better still. If your goal with the 300 wm brass is to lengthen the shoulder to case head distance by taking brass from the neck shoulder area rather than lower in the case body, both the false shoulder and bullet jam method might be worth a try. Keeping loads to the minimum end of published data of course.

[@HPAcustomriflesandcerakote]

I make what I call a square up on the lathe out of 1/2" barstock with a hole drilled through the middle which is for the decapping rod. When using bushing dies that to just BP the shoulder that aren't to where they aren't touching the shell holder I put the square up in between the shell holder and die. Put pressure on the ram and just snug the die enough it won't looses. With standard seating dies that are turned back a full or half turn after contacting the case mouth it's very important to use the square up. Threads are so coarse u can actually have the die misaligned with the shell holder if you don't do this. It's exactly why Lyman use to make the Tru line press with Tru line dies that were fine thread. For dies with a floating sleeve like redding comp seating die I don't use the square up because the die is made to make up for any misalignment. If I buy a forster with a floating sleeve it's the benchrest because it's steel with a stiffer spring, the ultra micro die is aluminum top and we're blowing the cap off so forster went to a weaker spring problem is it's to weak that it can't correct misalignment at times. Both 1000yd benchrifles I built my 7saum and 6xc I use lewilson micro chamber seating dies and a sinclair arbor press but for those two only

[@johnnash5118]

Is there a “better of both worlds” by using a SAC then a Redding? Seems like the Redding, with its sharper leading edge would create sharper neck-shoulder junctions and thus a slightly longer bearing surface.

[@SimpleLife1971]

Bolt Action Reloading has become my favorite reloading channel! The SAC bushings appear to have a lead-in taper which makes sense as it sits lower on the case mouth. I think this is important as it centers and guides the case mouth perfectly into the bushing. That said, I'm wondering if the shorter sized surface area can account for the lower seating pressure. The coating itself, appears to be a DLC coating, may aid in it working the brass less. Annealing: Do you anneal before sizing the brass regardless whether it's full length or neck only sizing? I'm wondering if annealing then sizing vs sizing and annealing last impacts the seating force and how does it affect accuracy. Another outstanding video!

I'll chime in by saying that I've used RCBS die bushings and, although it does have a slight bevel to help align the case necks to the bushing hole, the run-out seems to match your Redding example - roughly 0.001" as a general rule, with some odd-balls going to 0.002 and 0.003". It should be noted, however, that I'm still using the standard expander ball, not a mandel.

Very interesting material - since I am getting into reloading - I got most of the gear already, but still no bushings, I might go as well and start with SAC bushings. I wanted to ask how much concentricity affects what we will get on target, but I see that there is a follow up video on this exact topic. But what about a simple idea: if the "entrance" of the bushing is what makes the big difference -> wouldn't it be an idea worth trying out to ad a chamfer to a standard bushing (not the premium with special coating, because this would damage the coating), or simply (with a piece of sandpaper) smooth out the entrance in order to make the entering of the brass into the bushing better, just as it is with the SAC bushings? Maybe you have an old steel bushing that you could spare to test this?

[@TheOutdoorGeneralist]

Interesting! Makes me wonder what the concentricity of the inside of the neck looks like. With Lapua brass that already has a very consistent wall thickness at the neck, it should be excellent. But would less expensive or non-neck-turned brass do better with the expander mandrel method?

[@StuninRub]

The reason you are getting better performance on the non bushing die is because the bushing die is specifically designed for turned brass. If you aren't turning the brass, it won't make adequate contact. The non-bushing die is essentially taking your neck and squeezing it down 0.010" while the bushing die is only going down as far as the bushing you chose, which is typically only 0.002 for bolt guns. If you aren't turning your bass, just go non bushing and leave the default expander ball in.

[@michaelcheshareck3275]

If you aren’t neck turning would it be advisable to undersize with an SAC bushing and use an expander mandrel to open it up slightly, or is just using the proper size SAC bushing alone the best for consistency and performance?

[@StuninRub]

If you aren't neck turning, just use the standard non bushing full lenght sizing dies. Bushing dies are for neck turned brass.

Here is my observation. The further backwards we start worrying about concentricity, meaning we have a fired case from the rifle and now we begin the reloading process. 1st off correcting as many issues from a fired case, which is basically a blue print of your chamber will help your consistency with no doubt. With that said. I must have a completed reload to then check the concentricity of the bullet that is loaded in the case. And if at that point there is .002 or less of run out existing on the bullet seated in already in case. What other issues are there for concern???? What I’m trying to say is that I’m not arguing not to have a perfect neck but why don’t we wait to have a seated bullet before checking concentricity in the first place??? Imho

You get low concentricity, and don’t have to buy another bushing die and SAC bushing. I agree the SAC bushing looks great, and would be just the ticket, IF you weren’t following up with a 21st Century mandrel. I can’t see the need for both, but am open to being educated. (?)

[@craignmz5264]

It seems to me the bushing die wouldn’t give consistent neck tension unless all your brass had been neck turned to a uniform thickness.

[@greggkathy1892]

I totally agree! Maybe I just use crappy brass, and admittedly I have multiple heads stamps, but I am certainly going to neck turn everything before I commit to a particular neck bushing. I stopped neck turning after my first batch because I did not like the results on the Hornady neck turning machine. It was not very smoothe by my standards. Maybe I didn’t do it right. I’ll give it another go.

[@eddieb9110]

Have you used Wilson Bushings?

[@BoltActionReloading]

I have not tried them.

[@adamscholl8110]

Really dumb question here....is a Short Action Customs bushing compatible for use in FL bushing dies from other companies like Redding and RCBS?

[@BoltActionReloading]

If you pick the universal bushings, yes. They don't have a compatibility list, but I use them in redding dies. I'm not sure about rcbs, but I'm pretty sure they work in hornady dies. You can always email them if you have any questions.

[@jamesstanford8452]

Im about to take the plunge with die selection.SAC appears to be a company Id be content to buy once cry once with.For full length sizing die, would you suggest Forster, or Redding bushing die? P.S love your videos.Best Ive seen.

[@torreyintahoe]

I don't understand why you bumped down to .287 instead of .288 for the SAC die if you're looking for .002" of neck tension.

[@s.manuel7969]

I am using a .291 bushing and the seating force on my K&M press is 80-90! This is once fired Lapua brass that I have annealed. Why is it taking so much to seat?? Using Redding bushing die to size brass

[@BoltActionReloading]

That does seem like quite a bit. Are you champher and deburring well? Also brushing out the case necks?

Bushings size the neck. Unless you have a neck shoulder bushing which is not very common

I currently have just a standard FL Die, Is it worth upgrading to a Bushing Die or just finish with a Mandrel and call it a day?

@@BoltActionReloading I can't stop tinkering either the damn Rabbit Hole sucked me in so I'm trying to take a knowledge advantage of those of you that are deeper than me!

Will the SAC bushings work in the Redding type s die?

[@BoltActionReloading]

Yes

[@firstlight4165]

Your good!

[@Posercam]

Has anybody else heard or read that in order to set up the Redding bushing die correctly, you leave the the threaded top internal “bolt” slightly loose? You should be able to shake the Redding S die snd here the bushing go “click”, “,click” on the inside.

[@BoltActionReloading]

There is a ring on the die to keep it from moving but yes the bushing should be slightly loose. (we are talking like 1/16 of a turn here) BAR

[@equalleftrights3130]

Yes, but the sound you're looking for is "Clock", "Clock" which gives you .00002" runout. "Click" "Click" is not as tight..

I know it is like a year later, but thank you BoltActionReloading

[@stefanociccarelli2]

I am trying the Sinclair mandrel for 223 and I am not getting the results I expected. I full length resize with a Redding FL with the expander ball removed, and then I follow up with a Sinclair mandrel. The results are disappointing, both in terms of SD and group size. I discovered that the mandrel pushes my shoulder back. I use Norma brass and I am having the same results with once fired brass and with 3 times fired brass. Same story with Redding S dies. On the other side if I FL with the expander ball and then I use a mandrel, then I get better results. What am I doing wrong?

[@BoltActionReloading]

How much resizing are you doing with your expander and are you using any lube?

@@BoltActionReloading I still think using mandrel to push any brass imperfections to the outside is best. That is of course when a fired case lets bullet drop thru before resized. Cheers

[@stephenthompson9722]

It's all theory I want to see shots down range. If there is no difference then what's the point.

[@BoltActionReloading]

Hi Stephen, You are correct but its a different point. I do plan on putting some down range to test. Determining beyond a shadow of a doubt that runout causes your groups to open up is a different conversation than what busing produces the most consistently low runout. I tried to make the point that is all things were equal most would choose the least runout whether they saw the runout on paper or not. I agree completely that in the end what ends up down range is what matters, but then we have to talk about the error with the guy behind the trigger too. BAR

[@greendodge98]

Ok run out is half of the total measurement. What you are talking about is TIR total indicator runout

Concentricity and Runout are not interchangable terms. Throughout the video you seem to interchange the terms however you only ever measured runout.

[@dmtug1]

Don't use the expander with the type s die!!!! I have .001 to .0005 run out with these dies on all my rifles !!!!

[@BoltActionReloading]

I am not using the expander. I never use them. If I were using anything it is a separate step with a expander mandrel.

[@dmtug1]

Copy that. I have great luck with type S dies and I know that expander mandrels work. They work great with Redding Competition seating dies in my system. I don't care how you get there but for you and me both eliminating runout is the goal. The advantage I see with mandrels are they uniformly size the inside of the neck minimizing effects of neck wall thickness. Neck bushings forming from the outside will accentuate uneven tension with unturned necks.

[@herrprepper2070]

I suppose if you are shooting a Hubba-Bubba Super Five Thousand Match Rifle with a Filagree Rest… trying to reduce your group size by the width of a gnats bunghole, all this chatter about bushings and runout is worthwhile. Not for me. I’m content with a full length die and hitting a walnut at 200 yards.

[@D70340]

Concentricity is only going to be as good as the case the bullet is sitting in. If you`ve got shiddy case`s, and shiddy bullets, the fanciest tools in the world wont fix it. I can use standard dies and keep my concentricity at no more than .0005 runout. And that`s with using hornady`s shiddy bullets and basic USA made rifle case`s. I don`t need over priced fancy tools to make my shots hit the bullseyes. Over 50+yrs of reloading have taught me many things... like not wasting money.

[@MrNeverlost1]

Hi Larry My 45 years of reloading have taught me there is always something new to learn, to make our reloading process better, and make more accurate ammo. I would guess since you are also watching these videos, you are also looking for new ideas. I shoot 1000 yard and 1 mile benchrest competitions and need every ounce of accuracy my ammo can produce. Some of the new expensive tools help in that quest.

[@donaldhesler3715]

What is the runout of the Bullet once it is seated into the case? I don’t turn necks so I’m not too worried much about case neck runout but do worry about Bullet runout. I use Sinclair Bushing Dies and I very seldom get over .001 Bullet runout. I also use Starline Match (small primer) .308 Brass. Very consistent and about 5/9 the price of Lapua small primered .308 brass. Try some, you will like it.

[@Jeff_Seely]

Thank you for the video it's a great discussion. Perhaps your concentricity results with the bushing die may have something to do with your neck uniformity. I turn my brass down to 0.012 and then I use an LE Wilson bushing guy that is . 285. The worst I've ever seen is 002 and that is rare. I have been wanting to try the SAC bushings but they're always out of stock and quite honestly a bit pricey. Thanks for the video again!
