Re: need to know Barrel Twist on ruger m77mk2 .243????
Dont know it off hand.If you take a cleaning rod with a patch and just start it into the barrel then make 2 marks on the cleaning rod with a marker by the muzzle and handle and push the rod through until the mark near the handle rotates once.after it does make another mark by the muzzle,pull the rod out and measure distance between 2 marks made.
1-9 twist may be border line for this weight and might require a slightly faster twist.
