Barrel vise or action wrench

[hereinaz]

You don't wrench on the nut you use a barrel.vice and unscrew the action from the barrel.with a rear entry action wrench. you have index lines to make sure nothing moves.

You just tighten the barrel snug. 30 ft/lb is plenty. Some just hand tighten

It is really the barrel nut that is doing the work as the shoulder, the barrel is along for the ride, so the nut doesn't spin on the barrel-- but you gotta use the action wrench. Another reason some use action wrench....

If I'm understanding this - I could leave the scope on change barrels and only need to fine tune scope for caliber I change too. Would just need to have barrel nut on each barrel, head space set and loctite nut on barrel. This would work for me and the way I want to swap barrels.

Exactly. Some even inlet their stock where they can switch barrels without even taking the action out of the stock.
