I have a Savage model 10 I bought specifically on which to build a left handed 220 Swift. I am in the planning stages right now but am considering making it a fast twist, say 1 in 9, to handle some heavier bullets.
My ground squirrel and P dog days are over for the most part. I haven't been in many years and most of my shooting will be sniping coyotes, wolves and paper at potentially longish range. I assume a 55 grain will still do alright in a 1 in 9. How well will that twist handle the 75+ grain bullets? Should I consider a 1 in 8 and how do those two twists handle the light bullets, 40-50 grains?
In all the varmint guns I've had over the years, I've never had a fast twist 22 centerfire. Thought it might be time to give it some consideration with this build. Thanks in advance.
