BRass Swage tool?

Dave Tooley is rumored to be working on a swager for loose primer pockets; knock, knock, Dave!! Anything for a 308??? :confused: Overbore
 
It takes a tremendous amount of force to bring them back down. Then too, they seem to want to return to being oversized the next time you fire them.

I think what folks might want to consider, (if you're having this sort of trouble) is to take whatever tool he comes up with and use it before firing. You'll be work hardening the brass somewhat and it may take that initial firing better. In my experience, if you can allow the brass to break in slow, it'll last longer and the pockets won't blow out so soon, or ever.
 
Case head swager

Roll sizing is not a new science. It is done all the time for handgun ammo.
Scharch MFG. INC., and Howell Machine (AmmoLoad Worldwide) make comercial roll sizers.

Case Pro 100 makes a small roll sizer for hand gun ammo.

A better way of swaging rifle brass is pushing it through a carbide die. This only works on rimless and rebated headed cases. It takes more presure than an adverage home loading press can handle. But it can be easily handled in an arbor press.

Very few sizing dies get much below the case web.

Nat,
They are talking about tools that just swage the primer pocket. I think you stick a tool inside the brass and then strike the primer pocket to tighten it up. Kinda crude, but that is basically how it works.

Roll sizers

Butch:

Roll sizers and a carbide die where the whole case is press through it are the only ways I know of that one can tighten up a primer pocket. It is done on all comercial pistol ammo loadings. I personally own both a roll sizer and a Case Pro 100. I have seen a roll sizer for both .308 ansd .223. They are expensive and require an expensive collator.

Nat,
I know what you are talking about. I don't think they are. If you look at the link posted above in the Hart catalog, you will see what I mean.

I recently made a die to tighten up 6ppc case heads. I have a Rock Chucker press and it is all I can do to press a case through the die. I can push the case through about 4 times and get it to size down about .001". Like 4 Mesh said likely when I fire the case once it will be right back to the original dimension or maybe even before I fire them. Hard brass has a great memory.

Joel,
You can size the diameter of the base of the brass that way, but it will have no effect on the primer pocket.

Actually my die swages down the case head as well which will tighten the pocket some. The RCBS primer pocket swager works to tighten primer pockets for me. I know some have tried it and did not like it but I think if one learns how it works and how to use it then they can acheive good results. I have used it on magnum cases as well as 06 size cases with good results in tightening the primer pockets. The RCBS tool (RCBS # 09495) is made to swage military crimped primer pockets but works to tighten standard primer pockets as well.
 
Is the word swage really the correct word to use when you want to make something smaller? Wouldn't draw be the correct word? The word swage in bullet making dies have nothing to do with making something smaller.

Is that the meaning to a bullet maker? Is that what happens to a bullet, being made in swage die?. If it means to make smaller, then how does it fit this discussion? Swage = larger! which is exactly what happens in a bullet die and to a primer pocket when it's swaged, as in removing a primer crimp.

Then if the purpose of making the brass smaller in dia., I think the term swage is misused.

Here's one of the definitions from the link posted by Boyd. "5. to reduce or taper (an object), as by forging or squeezing. "
 
So you are saying that there is a die that will size the base of the brass down to and including the rim and that tightens the primer pocket? How can you accomplish this without over sizing the web of the case?
