Seen brass like this?

[rspar]

Pictures not so good but I've got a bunch of .30-06 brass that has a rim around the primer pocket. It's slightly harder to deprime. The only ID is R A 42. I'm new to reloading so I thought I'd check before spending a bunch of time prepping them.

brass is good to go. that brass was made for Remington arms by another company during the war. they basically had another company make 3006 ammo with their name on it, but they put that circle on it to know where the ammo came from. thats the basic info on it...

its good to load!

Might be Remington Arms made in 1942.

You might need these:
$10 - Hornady Primer Pocket Reamer Tool Large (to remove crimp)

$5 - Lee Decapper and Base 30 Caliber (for depriming milsurp or crimped brass the first time)

Could also be Raritan Arsenal... In any event, it's old brass, made in 1942. That "rim" is the military crimp that they use to keep those primers in place, no matter what. To reprime, you just remove the crimp or use a swager to bring that primer pocket to a condition that makes it easy to reprime. In any event, that stuff should be good to go!

So that rim was rolled in or something to crimp the primer in? It just takes a little extra to deprime no biggie.

Thanks for the help.

there is a crimp, yes thats just like the std USGI crimp. but i have Remington Arms ammo from 42 and the bottom of the case is different...thats what i was told..... either way it IS crimped and it needs to be removed before loading.

you will need to ream the primer pocket or you will crush or set off some primers.

I've chamfered the edge of crimped primer pockets with a countersink. No drill, just by hand. My buddy did some with a phillips screwdriver! Tool steel is harder than brass...

Get a primer pocket uniformer. It'll shave away a little brass and make the pocket ready for a primer. Should only be done once (Normally). If you ever crush a primer while priming, then you run it again. It's a relatively cheap tool, and you'll be able to use it on pretty much all Large primers.

Using this tool made about 200+ mixed headstamp milsurp brass good to load (many of them with the ring you describe). In fact i've just finished processing them all so they're trimmed, deburred, deprimed, sized, pocket cleaned and uniformed, and tumbled to a nice shine. Now i've just gotta sort the damn mess.

Thanks to all, headed to the show tomorrow hopefully I'll find some odds and ends to pick up.

you dont need anything major, i just use a razor blade and hold it at an angle, then roll the brass in my fingers to cut off the bur/crimp. You deffinately need to get rid of it though or you will mess up primers trying to push a new one in.

[Sky_DiveR]

A razor blade, huh? I hadn't thought of that. I'll have to remember that when I only have one or two to remove the crimp on. Thanks for the tip.

Went to the Ontario show what a waste of time. A great place to buy ammo but that's about it. Eleven bucks a person plus 8 bucks to park. Not to bad if your looking for a flashlight or an rc helicopter. Only a couple booths with any reloading stuff and mostly over priced a guy tried to sell me a used $20 Lee powder measure for 30 bucks and a $19 zip thing for trimming brass for $30 also used. My buddy was looking for a Saiga 7.62 but only found there newest tool release mag version for $550 - he wasn't interested.

Oh well Turners had good prices on powder and primers.

I think I'll stick with the commercial brass I have while I'm learning. Being new how would I know if I took too much off and the primer was loose, unless it fell out. Right now I'm just trying to get case prep down, I have a couple friends that reload and I'll have one of those over for the first day of actually reloading.

Thx for the help
