What tools do I need?

[flyin lizard]

I would like to change the barrel on my Sav.model 11 300wsm to something heavier/more accurate. The factory barrel is very thin and heats up real fast. Thinking about a shillen because they are pre-threaded and chambered for my cartridge.
My question is what tools do I need to switch the barrels myself , wrenchs, gauges etc.
Thanks Paul

Barrel nut wrench, barrel or action vise and a headspace guage.
