I've never actually seen anyone explain how to swap a barrel on a Savage rifle, but it seems like everyone does it.

1st question - What tools do I need to properly switch barrels on my Savage 10 FP? Barrel vice? Action wrench? Go-no-go gauges? Barrel nut wrench?

2nd question - What are the steps to actually doing the swap assuming I have the proper tools?

3rd question - What caliber? I want a low recoil cartridge, say less than or equal to a muzzle braked 30. What about .223AI, .220 Swift, or .22-250?

Thanks ahead of time!
