Great MB buck roscoe. I used the good ole .243 for over 10 years for deer. Always one shot. I took a deer 3 yrs ago at 360 yards (relaxed broadside shot) with the .243 with a fixed 4x scope, with a good rest. I'll be the first to admit that is pushing it for the little .243. But its a great deer cartridge. Switched to the .300 wsm just so it gives me practice shooting for moose/elk too.
