Re: HSM 338 Lapua
well got out and did a little shooting with some 300gr HSm 338 lapua. ran thru a trg42 w/ nightforce.
ran it out to 1000 and it was hitting reliably and easily at that range. made 1 big black spot on the white steel I'd estimate to be about 8" in diameter. wind was a slight factor tho too and sent a few flyers that still hit the 20 x 36 silhoette. Initial break in of weapon yielded some cold barrel inconsistencies at 100, but by the time I ran it back down from 1000 to 100, it was giving 1 hole groups at 100.
rounds went exactly where the ballistic computer estimated using litz BC and observed velocity at 1000.
