Hey guys has anyone ever used these? A buddy of mine swears by them and this weekend I shot my first deer with a rage and had not exit wound on a well placed quartering away shot through heart and lung at 21 yards (very disappointed in relation to my slicktricks) however he shot a doe with the wasp jackhammer and holy smokes! That thing is mean! huge hole it looked like he put her down with a .300 WSM double lunged quartering away blew through about 15 yards she went about 50 yards and crashed!
