One of my favorite personal guns is a A-bolt Stainless Stalker 300 RUM. I ordered several before the RUM's were gone. I built two nice rifles for customers, but kept one to build for myself.
I pillar bedded it in the factory stock, added a brake and a Moyer's trigger. It shoots 3 shots under 1/2" at 100 yards so I really don't want to mess with it. It likes 150 Scirocco's with a compressed charge of Retumbo. Getting 3700 fps out of the 26" bbl. I'd like to build a heavy barrel rig with it and put it in a McMillan stock, but it shoots really good for what it is so I'm holding off for now.
