Hate to ask this but I don't want to ruin a new barrel. I've changed several steel savage barrels for myself and a few others. I have always put the barrel in a vice to hold it and used a receiver wrench to hold the action while torqueing the nut. From what I've read, I can't hold the barrel in the vice because it could break the bond between the steel and cf. I want to install the barrel on a Nucleus action. I have an action wrench for the Nuke but can't come up with a way to hold the assembly while headspaceg and torquing. What would be the best way to do this?
