What kinda’ barrel life are ya’ll getting with the heavies? 200gr and up?
I’m getting ready for my third barrel. First barrel was 24” HV Bartlien 10 twist that went away after 1868 rounds, mostly 208gr AMAX and a bunch of 155 Scenars going way too fast.
Second barrel was a 23.5” Mike Rock M40 10 twist that I ran exclusively 208gr ELDMs and 208gr Berger Hybrids (both going about 2760).
I’m currently at 1845 rounds on the Rock barrel and it’s out of rifling in the first 4 inches or so of the bore. Only reason I bothered to look was the fact that it’s running out of accuracy at 1K.
I’ve got a Brux 10 twist HV and a Brux M24 contour on the shelf waiting.
I’ll probably get it re barreled in October.
I’ve got my own Serengeti reamer.

I have a Rock on mine and I think I’m in the 1800s as well, I have to look at the data book when I get home. I’ve shot nothing but 190s, 208s and 210 through it. So far there’s no loss of accuracy or velocity, the smith said the barrel should last about 3500 or so….
