I shoot a 05 Hoyt protec, 54 lbs, 28 inch draw. Carbon express 200s. I can't get 100 grain three blade muzzys to impact the same place as my field points. They are about three inches left at 20 yds. Tried moving the rest to the right, also left. However 100 gr slick tricks hit the same place as my field points. I think it maybe has something to do with the ferrel being narrow then widening the last part that makes them fly like field points. Just a guess.
