Brass question. LC brass with a NATO headstamp, reduce two full grains from max (thicker brass, less capacity) cause its Milspec. OK.

I got some LC Match brass with no NATO headstamp. Should I consider this brass Milspec also, and reduce two grains on it?

Does LC make any non Milspec brass? Or is the Nato headstamp the defining identification of Milspec?

I'm talkin 7.62 here but I suppose the question could apply to LC 5.56 brass also. I do got some LC Nato stamped 5.56 and some LC non stamped 5.56 also, non match.

Weigh the brass.

The only difference between LC Nato and LC Match brass is the headstamp.... and that Match brass does not get the primer crimped in.

Other than those two minor differences, they are identical and come off of the same machines-process.

Swampy is correct.

Consider .308 and .30-06 LC brass "mil-spec" and reduce your loads. .223 LC does not need to be downloaded.

Many thanks.

My primer pocket swager (RCBS) worked good this time. The first time I used it I sorted by headstamp but not by year, and I bent the rod.:(

Worked real slick this time.:)

Thanks again.

There is a ring of knurling around the head of most LC Match brass as well.

[Edward429451]

Yep, its knurled allright. I thought I'd mark some of my other brass the same way with a cannelure tool for positive identification. Got about 4 or 5 pieces done and my tool steel cannelure wheel was smooth. :what:

I'da never thought that would happen. Soft yellow brass...tool steel?:banghead:

[Pumpkinheaver]

Damn that must have been some hard brass to mess up a hardened steel tool!!!
