What twist barrelPics
Call Cooper with your SN and they will tell you. You can also push a cleaning rod in the barrel and measure the twist per inch yourself.No idea. How would I find out?
I would think it would be. But I've seen 9 twist 264s stabilize 140 A-Max's. Also coopers test targets are shot at 42 yards.Their test load shown here is with a 142 SMK it requires a 1/8 twist to stabilize so I would bet a dollar to a donut hole that's what it is
