Hello all, I've got a jp supermatch 14.5 308 with 1.11 twist and I was wondering if anyone has had any success with their load development in getting sub moa and what that load consists of? I'm not looking to go past 700 yrds with this barrel, but would like to be sub moa at 100 yrds. Thank you for any and all input. 🤙

Because of that short barrel, I'd work up a load using a rather fast burning powder, like IMR 3031 to get you nicely out to 700 yds. You'll be able to fill the case nicely, which helps with consistency and it should give you MV's above 2450 fps with pills like Berger 175 OTM's. As I've never use a barrel that short, so I don't know, but think sub MOA might be quite a challenge, especially out to 700 yrds.

I'll have to pick up some of that imr, as I normally run vithavouri, varget, blc2, accurate powders. I also have some 150gr Speer match bullets and 155gr amaxs that are at the gun shop. This barrel is more for hunting caribou and also mostly fun, I'm just seeing what I can do with it. I also purchased some LaRue 762 magazines to get a little longer oal. Much appreciated on the info man 🤙
