Because, uhh, they kill things. Shot a yearling buck Sunday at 389 yards with the 210 JLK from the Wolf. That poor thing died within 10 yards of the hit - 3/4" hole on exist and lungs in tatters when I pulled them out. Shot a doe Tuesday morning at 225 yards with the 105 A-Max from my 6mm Remington. Died within 5 yards of the hit. No exit wound, top of heart and one lung obliterated. Chalk up two more kills for these poor, pathetic projectiles!
