I have 3 Savage actions that may or may net get swapped between multiple barrels.
3 EGW 1 piece 20moa bases.

I bedded all three bases to the actions(used release agent and popped off after set time).
Some say that with good fit, bedding is not required, but it is so easy to do.

Then cleaned/degreased and reinstalled using blue loctite.

Tighten with adjustable torque screwdriver.

Forget about them after that.
