reaming vs. swaging primer pockets


Registered Users do not see the above ad.


I am looking for some opinions on reaming and swaging of primer pockets. I have a bunch of .223 military brass that I would like to reload and need to remove the crimps. any help would be appreciated.

What I'm trying to avoid is of course over sized pockets. I de-cap as a seperate operation and once in a while you have a primer that practically just slides out.

How important is the fit ? I realize that the bolt face stops the rearward progress but what effect does it have, if any, on accuracy. I'm not talking benchrest accuracy just 200 yard or so . My plan is to use the rounds in my SCAR16s.

I use a little countersink reamer on my Lake City 5.56, and have never had any problems with that approach. I think I paid about $7 for the countersink.

I use the rcbs swaying combo. Works fine.

I would have bought one of these if i had a ton of cases to swage. It looks just like the Dillon, if you go to the RCBS web page and look at new products.

I shoot alot of military .223 brass varmint hunting. Use a countersink in a cordless drill, just takes a second to remove the crimp and pockets still retain a good fit.

I recently used a deburring/chamfering tool and a cordless drill to remove the crimp on ~200 '06 cases. After learning from that process, there's no way I'd pay $80 for a bench-mounted tool to do this, unless maybe I had thousands of cases that needed attention. A simple countersink, with some careful experimentation to determine how much pressure to apply and how long to hold the case to the cutting surface would be a simple and effective solution.

If you want to get fancy, you can buy the handheld tools from Hornady and chuck those up.

No way I would pay $80 either. How about the $30 RCBS primer pocket swager kit that mounts on any single stage press? I'd spring $30 for that one.

If you look at the OLD products, you'll find RCBS also sells a $30 primer pocket swager kit that fits on your single stage press.

Yes, if I had a large volume of cases to do, and I wanted to swage instead of cut the crimp out, I'd gladly pay 30 bucks for the RCBS kit that mounts on a single-stage press.

In your experience, is it "better" to swage the pocket or use a cutter of some kind on the crimp? Are there any inherent advantages of one over the other?

I use the RCBS swager deal that Marshall mentioned and it worked wonderfully.
Now that I'm old an lazy I find it simpler to buy the already cleaned up and decapped cases.
A few years ago Midway had a great sale on 308/7.62 in packs of 2,000.
Now all I have to do is trim them to size and separate them by weight.

That's the one I got, and it works great. Glad I got it, too, because lately I've run across some federal "American Eagle" brand .223 that is lake city primed stuff that's crimped. The RCBS swaying die is quick, simple, and effective.

IME, the swaging tool rolls back the crimp and "rounds" the edge of the primer pocket where the crimp used to be. No metal is removed from the pocket. It takes a bit longer to swage the pocket than to cut it.

Whereas, with a cutter/countersink, metal around the mouth of the primer pocket is removed. How much metal depends on the skill of the reloader.

Both methods work so I can't say one is better than the other.

Cosmetically, I prefer the swage but only for appearance sake. Swaging makes the crimp disappear whereas cutting it leaves a chamfer. YMMV

I have both tools (Lyman hand-held primer pocket cutter/reamer & the lower-priced RCBS swaging tool for a single-stage press), and have used both on crimped military brass. Each tool works as advertized. As Marshall Kane noted, exact outcome of the cutter tool depends upon the skill of the operator. I prefer the swager, but I'm not sure I can call it 'superior' to the cutter, except in purely theoretical and/or aesthetic ways.
