A good reason to buy a picatinny base, IE you can pull the scope and rings and they usually go back on within 1" for me. Use a good base and good rings. I use extreme rings.

With a 1-4x or 2-7x or other short scope you can leave it on. At least I can with an EGW base.

I only use a barrel Vise, IE no action wrench, but only for the initial break.
It can be tricky to get the nut off the first time as they are gorrilla tight from the factory.

I have had good luck with this.
Alum barrel blocks.
Tooling leather. Had it laying around. Stiff and about 1/4" thick
Confectioners sugar to keep it from spinning.

Wrap the barrel with scotch tape where you will clamp it prior to clamping down on it and that prevents marring if it does slip.
Don't use tape on a painted barrel.

Whack the **** out of the wrench with a heavy hammer


Once its off it is easier from then on.

I dont even use a vise for swapping. I just hold on to the action and give the wrench a few solid hits with a hammer
to tighten. Reverse to loosen.
