I just bought an older 111E in 30-06 and am having trouble getting the barrel nut off. I bought the wheeler barrel vise and some rosin for the wood blocks. I sprayed some liquid wrench on the nut and tightened the blocks as much as I could. The barrel is slipping in the blocks? I also tried some heat on the nut. I am assuming the nut turns left to come off? Any ideas on what to try?
