RE: .223 or .243
Last year, I opening morning of the gun season, a decent sized yearling 3 pointer (which I actually thought was a 6-8 pointer, because it had a 13 inch spread, but anyway) stepped out 75 yards away, a made a grunting sound with my mouth, and my .243 destroyed his lungs, and took off low and hard and I found him 30 yards away...
People who say a .243 will allow the deer to run forever simply cannot shoot
