Military case swaging question
Does the Dillon swager also press any kind of radius to the primer pocket? I know reaming would, but that isn't something I want to do hand held a bazillion times.
I have a lot of 5.56 and 9mm to swage. Would like to cut down on the steps I have to repeat thousands of times.

The problem with swaging is brass spring back .
No matter what the brand of the tool you will get some brass spring back ... some lots of brass spring back more than others .
After 50+ years of reloading , 9mm Luger , 45 acp , 30-06 and 308 military brass , the best way to do it is :
1.) Swage
2,) Clean up with a reamer to cut away any pesky spring back .
3.) Finish with a Primer Pocket Uniforming Tool. This makes all the pockets the same diameter and depth...takes care of any spring back .
Yes it is 3 steps , but when you are done all your cases will be easy to prime ... not some easy and some hard... and after it's done once you are done .
I hate to say it but swaging alone just doesn't do a complete and proper job .

I've found most fairly recent (this century) production 5.56 MM cases pretty much require primer pocket uniforming for proper primer seating. They seem to trend to the SAAMI minimum primer pocket depth. The DOD focus is on first (and only so far as they're concerned) use, not reloading. They probably think SAMMI is a pole dancer at some local saloon.
As noted above, some cases are crimped firmly enough that a slight chamfer after swaging is a good idea.

ROTFLMAO!!!!!!
I prefer to just use a primer pocket uniforming tool. Mine are old, Lyman pieces with a wooden handle. Slow, but it works well.

I use the Hornady LNL Primer Pocket Stage tool. Mounts on any single stage press. .223/5.56 and .308 version available.

Yes, the Dillon swager does press a small radius to the edge of the primer pocket. You can see it in the shape of the primer pocket dies. I also usually run a Sinclair primer pocket uniforming tool into the pockets, but just to clean up and square the bottoms.

I have used the RCBS primer swager for over 30 years. It does leave a slight radius if adjusted properly. I have never bothered with uniforming the brass either.
