Military vs. Commerical Brass Debate
After talking with some fellow shooters locally and reading on the net I must
ask this question again.
Any difference between military 5.56 brass and commerical .223 ?
Most the shooters in my high power circle say they use the same loads - i.e. powder charge - for commerical or military brass, there is no significate volume difference in 223 brass. I read this as well in a couple articles on the net, but also read that when using military brass reduce powder charge 2 grains from a previously used load with commerical brass. But did not specify
what calibers.
I weighed some cases and the weight difference is around 5 grains.
Any and all comments and experience would be appreciated on this topic.

My experience has been the same. Just check the lot of brass if using max or near max loads if you get a fresh infusion of supplies. I still segregate my brass by mfg. (and year) just to keep things consistent.
ETA Oh, BTW I haven't had to reduce charge weights w/ either brass type.

lapua vs. LC brass
Both new brass, sorted by weight, mouth of cases beveled, sized at neck, and trimmed to same length. Could not tell a difference in accuracy using any powder and bullet combo. I think that I like the Lapua cause it says Match on the base. Oh well. the price is really up there for the lapua, and so I really will stick to the LC new brass.:
