[QUOTE="Rustystud, post: 393246, member: 9964"] Barrels are tightened by gorillas at the factory because they don't want just anybody taking the barrels off. This is a liability thing. Savage barrel nuts are not engineered for more than about 50 ft lbs of torque. They will warp, and break if over tightented. I get them right then smack the wrench with a rubber mallet. Just tight enough that they want come loose. Some of the wrenches have a socket for a torque wrench. With good 2B threads they will tighten up to 50% thread contact at 50 to 70 ft lbs. Make sure you lubricate them well with a high temperature molly grease or use an anti seize. Rifles being rebarreled do not have to be factory tight to be safe. Especially actions that will see many barrels over their life span many times. One can eventually warp or pull out the threads by over tightening them. Nat Lambeth [/QUOTE]
