22-250 accuracte load trouble

[Shane in WI]

I thank everyone for their help. I have been letting the barrel cool between groups. I might be wrong, but I wouldn't think 3-4 shot groups would give enough heat to cause the problems I'm having. Barrel is plenty cool enough to touch.
I have a few more loads to try tomorrow w/ different bullets. I may keep this gun for a hunting rifle and look to buy a heavier barreled gun to do what I want. Any suggestions on rifle brands for a "hunting/target" rifle? I don't have any rifles w/ the laminated stocks so I think this would be a good place to start.
