lapua brass?

[dcb]

I finished fire forming and preped 100 rounds 243AI lapua brass and the weight was from 172grs to 174.8 grs
173.4grs average. 2.8grs total
What percentage do you use for 1000yrd.. the hole lot is well inside 1/2 of a %. thinking about 80case or so for a lot.
any comments welcome

I think if your goal is a world record group at 1K then 2.8 grains differance is unacceptable. If your goal is .5 to 1.0 MOA at 1K I think you ought to do just fine.

Any time you want better than .5 MOA at 1K, you want EVERYTHING to be the same.

For my 1KBR brass, i take lots of 20 (enough for sighters and 10 record shots) and they vary +-.1gn

Is this needed? Probably not, but it gives me warm-fuzzies /ubbthreads/images/graemlins/wink.gif
