My friend in Wyoming builds his own guns,and his favorites are a 300 Edge,and a 6MM. Ackley Improved.He has Huskema Blue Diamonds on both of them.I witnessed him last December shoot a cow Elk at 950 yds. with a 117 grain Matchking, two shots two hits in the lungs about 8-inches apart! The conditions were near perfect,and normally he would not have taken the shot,but he does alot of shooting through out the year,and was confident he could make the shot,according to his calculatons, he still had 1100 lbs. of energy left at that range with that bullett!
