hello everyone. been a member for awhile. alot of knowledge on this site. need to ask a question so decided it was time to introduce myself. I am having a 375 h&h built and and cannot decide between a 1:12 twist and 1:10. plan to shoot 270-up to the 350 grain barnes. I have a 338 for anything below that. What is everyones thoughts.

Welcome to AH posting side. I believe if not mistaken the typical twist rate for the .375HH is 1:12. My M70 shoots equal accuracy with 250gr and 300gr heads. I guess its possible you'd want the 1:10 for 350gr projectiles, but I'll have to let others chime in on that.

Measure the bullets you want to shoot...

The basic formula goes like this-
Bullet diameter squared, X (times) 150, divided by bullet length, equals the optimum twist rate in inches......

My custom 375 ruger is 11.5 twist. Shoots everything exceptionally well
