You can look up the particulars of each bullet you're thinking of using, caliber is .284" of course, length, weight, B.C. and load the info into the Twist Rate calculator on the Berger Bullet web site.

A 1-10 twist will comfortably stabilize a 150 Partition for example.

Bullet length is more important than weight in my experience but the calculator will help you sort that out!

PS, Welcome to the 'fire!

You will remember a curve of your wagon track in the grass of the plain like the features of a friend."
