I was not able to find the recent thread on this subject, so I will start a new thread. In the last thread members posted that the newer Ruger M77 MKII rifles in caliber .223 Rem. had a rifling twist rate of 1 in 9 inches. I was curious and I attempted to measure the twist on my MKII Stainless Synthetic. I bought it NIB somewhere around 2001 and it had the new style plastic stock. After many times running a tight patch down the bore and measuring the length of the cleaning rod travel after the rod made one complete revolution, I came up with 1 turn in 10 inches to 1 turn in 11 inches. I did this at least 10 times and do not think I was getting an inch of slippage. I believe the twist is one turn in ten inches. What say you?
