Primer Fit Problems

[SunkenShadow]

Hey guys,

So I posted like a week ago having problems with the FL sizing die on a Lee press, good news, it works now. Bad news is that I have a new problem.

So here's the new problem....I am currently using 1957 Yugo, 30-06 brass to reload my M1. The problem I am finding is that the current primers I'm using, the Winchester LR Primers, aren't fitting so well. There are a few cases that fit REALLY well and A LOT of cases that don't fit at all, no matter how much pressure I put on the auto-primer. Would you guys have any idea what's the problem? and do you have a solution?

Equipment :::
Lee's Auto-Prime XR

Materials :::
Winchester Large Rifle Primer
1957 Yugoslavian .30-06 brass, once-fired through my M1.

Thanks in advance.

Sounds like there's a primer crimp that has to be removed.

yep, if the brass is soft you can use a deburing tool.

Get one of these, it'll make short work of the crimped primer pockets.

If you don't have anything else, use a pen knife and be careful to just remove crimp. 45degree countersink from Ace hardware will also suffice. Same caveat, don't be too energetic in removing material.

Seems kinda dangerous. I would suggest using a chamfer/deburring tool and reaming the sucker out. But go slow and don't take off too much material.

donger - what is dangerous ?
You only want to remove a bit of material at the outer edge of the primer pocket..
You DO NOT want to ream the bore. -
The proper tool - either a cutter or swager from lyman/rcbs et al is of course best over the long run, but other tools will do for short term.

I think trying to manipulate the case with a hand and cutting at the crimp with a pen knife is dangerous. My opinion.

Perhaps you should take up knitting -

Show me how to use a pen knife to cut out the primer crimp buddy.

Some people have sausages for fingers and/or kinda clumsy and a knife/razor is always dangerous if you're careless.

Moving on, you could always go on the cheap and use a 1/4" drill bit and do the same thing without too much danger of slicing yourself... but then again there are those people that will slice themselves with a butter knife.

All the other suggestions above will work also. I use a primer pocket uniformer so it takes care of the crimp and uniforms the depth of the pocket at the same time.

RCBS makes a primer pocket crimp remover for both large and small primer pockets. I've tried using the primer pocket reamers and the RCBS is much faster and uniform. Just my $0.02
