I took a nice muley also in Wyoming this fall using a #1 7MM-08. 140 grain Sierra Game King took out heart and lungs and folded the deer right now. The recovered bullet retained 85% of it's original weight. The shot was about 125 yards.
I'm thinking that these Sierra Game Kings are a tougher bullet than I'd once thought. Use the appropriate weight for the cartridge & game, and all that good old common-sense knowledge.
Congrats on your muley, especially with a Number One.
BTW, the steaks from this buck have been excellent! May have been somewhat due to the alfalfa fields not too far away...
