10mm brass

[Old454]

I am new to loading 10mm ammo but not new to reloading.

I load on a dillon xl650

I ordered once fire range brass and most of the brass is ok. The problem I am having is with S&B brass and priming. It is just mangling primers.
Anyone else have these problems ?
Also see Blazer Brass with small primer pockets.

Any help with brass choices would be greatly appreciated

Thank you in advance

Hey Old454,
New Starline brass isn't terribly expensive and has served me well

Old454, welcome to the forum!  You may have some brass that has staked pockets as several are doing this these days.  S&B brass may even have slightly smaller primer pockets on their newer stuff.  You can Swage or ream the pocket and or use a tapered reamer to cut the staking...

Also be were that there can be small primer pocket brass as well, usually stamped "NT" for Non Toxic 
If you have a small primer pocket reamer try that to see if it helps with your priming situation!

Best regards and good luck!

I've found S&B brass to be bombproof...good for a dozen or more reloads, but I hand-prime.

[Old454]

I think I have an alignment problem with my dillon xl650. Dillon is sending me an alignment tool.
That should help with seating in S&B cases.
Now I am finding Blazer brass that is small primed... uggg not fun lol

Really? 10mm brass with small primers? Or 45 ACP brass with small primers?

This is the third report I have had of 10mm small primer.  Small primers are the wave of the future most likely for all but the very largest volume cases.  A small primer has plenty of pop to light 15 grains of powder and carries far less highly toxic compound.

I too just got some misc brass including some S&B brass. I haven't worked with these yet, but if I were having the issue you are I would first use this tool;
https://www.amazon.com/RCBS-90387-Military-Crimp-Remover/dp/B0063IDEK6/ref=sr_1_2?dchild=1&keywords=rcbs+military+crimp+remover+large&qid=1588110838&sr=8-2

And then use this;
https://www.amazon.com/RCBS-Primer-Pocket-Uniformer-Large/dp/B000N8N3GM/ref=sr_1_2?crid=1P0ZZHQBUBGEN&dchild=1&keywords=rcbs+primer+pocket+uniformer&qid=1588111029&sprefix=rcbs+primer%2Caps%2C350&sr=8-2

The first tool will clear the way for the uniformer tool.  If this doesn't help holler back.
I've haven't heard all good things about S&B brass, but I'll find out for myself soon..

You can find these about anywhere online or at a good gun shop, just happened to have Amazon up..

Hey just an update..
So I was punching out primers on the mixed 10mm brass, getting them ready for SS pin tumble, I noticed some spent primers were noticeably more difficult to punch out. When I looked at the head stamp.. S&B every time. CBC's are staked in and some of those had more resistance coming out, but not as much as the S&B's..  Hmm..  More later

I have Dillon's Super Swager (I drink blue Kool-Aide), but I'm not even sure it'll work with pistol cases...

Best option for primer pocket swage:  Dillon Super 1050 (I guess now 1100 or 2000 processor)

Best option for primer crimp ream:  RCBS Chamfer / Debur 17-45 tool.  The "tail" on the debur side of this tool can be chucked into a drill and really quick buzz in the primer pocket removes any crimp.  Be very careful, you can remove too much if you go more than about a half second.

Runner-ups I have tried:  RCBS Primer Pocket Swage dies.  Don't waste your money.

Viable options I haven't tried:  Dillon Super Swage.  While $114 + $22 for the 40 S&W adapter seems a bit steep, if you have a bunch of brass on you have to swage instead of ream, this is probably the option.  If you just have a couple hundred, just use the chamfer tool

I have been using the Primer pocket reamers when I need to, I use mine in a hand held handle, although they can be mounted in the case prep machines.



Recently I acquired a Lyman pocket uniformer that works well too!

Hey Bimmer
I've never used the Dillon tool but I'm sure it works fantastic on 5.56 and or 7.62x51 brass if you load those. Can't say how it would work on 10mm..
I use the RCBS Bench Swager for 7.62 Nato/5.56mm and it works great for that. Then I started using the RCBS Military Crimp Removal Tool as I can install it on the Case Prep Center and just add that process to all the other case prep operations. The Removal Tool will put a commercial bevel on the mouth of the primer pocket without any guess work, quick and easy. You can't go too far with it. If you don't have a prep center, you can use a handle or a cordless drill.

I've actually seen range brass where way too much of the primer pocket was eaten away!.. Someone didn't understand the concept..

Anyway I thought this would be an inexpensive solution to the funky primer pockets we're running into.

[Old454]

I have the Lyman case prep machine that will uniform the primer pockets.
As far as taking out military crimps I use a counter sink and a drill it works very well and is really fast.
I have used it on 5.56, 7.62... I will pull all my S&B brass and uniform it all and Monday my alignment tool for my press gets here from dillon.
I will try to post some pics of this S&B primer problems and the small primer cases

[Old454]

Hmmm how do you resize pics so that I can post them ?
