I have both a 300 stevens win mag model 200 and a Ruger M77 Mark II 7 mm mag in my stable of pups...other than that I have a 308 and AR15. I would like to chose one and build it up a bit to make it a better long range target gun. It might be used for hunting, but right now the aim is to shoot paper and steel. My goal would be to hit a target at 1000m. Might not reach that, but the process and challenge are often the most rewarding. Which gun should I choose? My guess is the first two would make the best candidate. And what can I do to improve it? I am setting aside $1K for a scope. My next priority would be recoil reduction (if that doesn't decrease accuracy). Maybe a muzzle brake? And a new trigger? Though i have read that a GS can adjust the pull on the stock to 2.5 pounds. Any other suggestions?
