the .243 is my favorite round. I have shot several deer with my 243 and have dropped every single one of them in their tracks. 2 years ago I shot my biggest deer ver with my 243 and dropped him in his tracks. He was 186 yds away and he field dressed 285 and my 243 smoked him. I just made my longest shot on thanksgiving with my 243, I dropped a buck in his tracks at 427 yards. It is all shot placement and i personally love the 243.
