Primer pocket treatments

I've done a quick search but, I haven't found an answer.

______________________________

I usually shoot semi-auto hi-power rifles, in .308 Win. (7.62 NATO) and .223 Rem. (5.56 NATO). I use a lot of once fired military brass that has the problem of a crimped in primer. Yes, a non-crimped brass case from a major mfn would be better but, let's forget about the commercial cases.

So, What if.........all of the usual BR style case prep steps were done exactly alike, the ONLY DIFFERENCE being the method used to remove the military crimp. For accuracy at long range (600 yds.).........which method would be BETTER for the treatment of a military crimp?

Swage or Ream​

Can anyone direct me to a published article OR just give me your .02 on the subject (or even for tests done at a closer range)?

Aloha, Mark

military crimp primers

ma96782: The Dillon swaging tool is popular for high-volumn, but I've never used it. I have the Forster case trimmer, and for a few dollars you can get a cutter that will do a nice job of cutting the military crimp from the primer pocket. Works great on my LC brass.:)
 
Dave D,

Thank you for your warm welcome. I'm sorry IF you feel threatened by my intrusion into YOUR space.

BUT.....

For the more "friendly folks" out there......the reason I ask here on this forum........is cause I respect your opinions. I feel that IF anyone was looking for the tops in the accuracy department.......that would be the Bench Rest Shooters.

Thank You......for whatever information you can provide.

Yes......I KNOW of the Dillon and various hand held tools that are available to de-crimp. Yes, I agree that for 1000s of cases (at one sitting) the Dillon can be fast and simple. While the hand tool can also be fast for smaller batches (though somewhat rough on the hands- cramps).

BUT........I'm just asking, IF anyone has done an experiment, know of an article, or through personal experience........between either method: which is better for accuracy?

Aloha, Mark
 
I'm willing to bet any method that allows you to seat the primers without distortion is just fine with no noticable difference in accuracy.

Now if your brass had a military crimp on the neck I'd be worrying about its effect on handloads. They usually do not just blow out and go away to easily.
 
Emayninetysixthousandsevenhundredandeightytwo,
You should feel lucky that you didn't have to answer a "mystery ketchup shelf life question" to get in to this forum.Most new guys get roasted alive over a trash fire as part of their initiation!
The only reason I'm responding, is that when I started out I would dig through the trash cans at gun clubs to salvage once fired brass in .30-06,.243,and .22-250.Finding this garbage I thought I had the world by the a--! What a big waste of my reloading time!
Being as you're interested in accuracy?; and you are asking about it on a BR forum,here's my opinion.
New brass of the same manufacturer and lot# and fired in your chamber is the ONLY brass worth reloading.(that's PERIOD) If you just wanna go "BOOM",knock yourself out with "Vietnam jungle thrift store brass,"but don't expect one hole groups! But you already know that, don't you?
So get a paper route,shovel some snow or find a way to come up with 20 bucks for a 100pc bag of new Winchester brass and leave us alone!

Thank you for your well thought out answer/opinion. I guess.....you can't read very well.....but, I won't hold it against you.

Yes, a non-crimped brass case from a major mfn would be better but, let's forget about the commercial cases.

PS.....I don't have my secret de-coder ring or know the secret handshake, yet......so, is a simple Kowtow enough?
