On my annual trip to Montana, I take 3 rifles to shoot the dogs, .223 for most of my shooting, 22-250 ai and a .243 loaded to 4000 FPS. I have never had a day where I shot over appx 300 rds from all combined.The .243 obviously has the most recoil and can get tiresome, but is the most fun, most explosive! Usually the sun and wind are more problematic than the recoil. As far as muzzle blast I shoot them all suppressed.
