RE: Grim Reaper 1 3/4" OR Wasp Jackhammer 1 3/4"?
This will be my first year with the Grim Reapers, the bigger ones. I've been shooting them quite a bit into various mediums, and am happy with them so far, very happy. They have opened every time, leave a great hole, and fly awesome. sorry I don't have experience with the Jakhammers. I shot my reapers into a ham (pork), just for research's sake, and they broke the bone with the head undamaged, so they are certainly tough too.
