Working up 1st 7PRC Load ... hmmm

[Trm82]

280 rounds through my 7prc now, it shoots faster, and more accurately, it easily shoots 3/8" moa @100 yards.

I think mine does 3/8 moa at over a 1000 yards.I didn't measure it but it would close
They definitely are shooters.

What bullet and load is this with? Have you ever done a 10 or 20 shot group (3 groups of 3 or 7 groups of 3 using same POA) to validated the group size?
