I have used the rocky mnt. snyper for the last three years and had no problems. Out of the 9 deer I shot with them only one made it out of sight before dying and it only went about 75 yards, all with pass thru's and one of these was an Illinois buck that dressed at 227 lbs. I only went to the rage because of the bigger cutting diameter and shot a buck with them this year got a complete pass thru and he didn't make it 20 yards, so if your not getting pass thru's it might not be the broadheads. I did find that the blades can deploy out if bumped so I might try the rubber bands
