7mm SAUM Build Help

The better advice here, is to get advice from guys/gals that are running same caliber weight bullets in similar cartridges at varying degrees of velocity. Or call the bullet experts, ie Berger, Hornady, etc. To mix calibers is just not good reference data or a good practice. Not to mention quite confusing if someone is new to the game and starting out.

As the chap above stated, he's running the 140's from a 8 twist with no issues.

Agreed. That is best practice. My 6.5 prc is 8 twist, as is my 7 saum. They both love it. Case closed

Wait, don't forget about the 8.5 twist!
