If you cannot get these broadheads (or any quality broadheads for that matter) to hit on top of your fieldpoints then the bow is not tuned. I can switch from Muzzy 4 blade, to magnus 2 blade, to NAP TH 3 blade and they will all shoot the same as long as the bow is tuned and the BH is not a wobbler (spin test to confirm). Muzzy 4 blade heads are great. I shoot the 100 gr version. This was the latest harvest (first arrow in quiver was a pass-through and the visible arrow was a "coupe de grace" that really wasn't necessary but did it to quicken the process.
