I currently have 19 rifles chambered in .22 Magnum, plus a few Savage 24 combination gun, and a few revolvers. If I had to limit myself to a single .22 Magnum it would be a Marlin 983S with a Rifle Basix trigger.

My friend, Andy, is a subsistence farmer, rancher, hunter, fisher, gatherer in NH. His everyday carry firearm is either 783s or an 883s, I can't remember which, and he supplements his diet with small game that is killed with that rifle.
