a brass question

[adrians]

hi , i have some once fired L.C brass its marked L.C 42 and L.C 52,.
my problem is i cannot seat a primer in them .
are they some kind of military designation or something or am i using the wrong l.r primers( they are reg center flash hole shells, can,t see any crimp in there either). have a great one .:evil::confused::twisted:

You may need to swage the primer pockets.

[mdi]

Try a 60 degree countersink (or a champher tool) to break the edges of the primer pocket. 1/32" or 3/64" should do it.

[mooman76]

They are military and they are crimped. Like stated you need to remove the crimp.

As mentioned, most military ammo has crimped primers to prevent them from backing out of the pockets when fired/jolted around in an automatic weapon. There's at least two methods, ring and stake crimping, although you may just have tight pockets. After depriming the case, the crimp must be removed before seating a new primer or it will be crushed/deformed and useless.

It's an old problem and been around for years. Fortunately the reloading community is a wise bunch and has answers! After all, good brass shouldn't be rejected for any reason.

RCBS (and others) make a primer pocket swaging device (uniformer) that screws directly into your press and will push the crimped brass over in addition to making sure the pocket is to SAMMI standards. It's not expensive. I've found that it's best to swage the pockets, then go back through and use your case mouth reamer to cut a small bevel at each pocket edge.....a trick given to me by one of this forum's members. That little bit of bevelling made all the difference in the world.

The LC is for Lake City and the 42 and 52 are the years of manufacture (1942 & 1952). Though it is dangerous to assume, I would assume this was for military use and the primers were crimped in place. You can carefully use the chamfer tool as suggested but that does remove some metal, something I would be hesitant about. A far better method is to use a primer pocket swager such as this one. http://www.midwayusa.com/viewproduct/?productnumber=447022

I have tried many of the primer pocket tools, and have come to the conclusion I like the Hornady one the best (for my needs).

I use the RCBS primer pocket swager.

Works nicely.

A small, sharp pocket knife also works if you have more time than money. After all, you only have to do it once.

As mentioned above, the Hornady reamer tool works well. Just give it a twist and the crimp will be gone.

Midway and Grafs both seem to be out of the small one right now, but I believe you can backorder it.

I reload lot of military ammo brass and Dillon crimp remover does great job but then if not loading in the thousands as i am then there are some good ones that work great but i bite boolit and bought the Dillon before got carpal tunnel sydrome.

[Moonie]

I use the Hornady without handle chucked up in my drill, it bottoms when done. I can do alot of brass in a short time this way.

[Doby45]

I have both the Dillon Super Swage AND a 60* chamfer that I just happened to have in my tool box. I love the Dillon for large lots of brass but the chamfer also works perfect AND the chamfer actually worked better on the **** FC brass I got because it removes just the very lip and therefore the crimp but it did not loosen the pocket.

[Larry Gibson]

I also use the Dillon and a counter sink, both work excedingly well. Gave up on the RCBS primer pocket swager. Haven't used one but the Hornady tool looks pretty good too.
