5 shot, I have used those heads some and like them a lot. Not any official test but I have shot the Gators and Muzzy 100' s into the same 3d target before and got about 10" more penetration out of the Gators everytime. And the deer that went down the quickest for me was with a Gator ......in about 20 yrds and 2 seconds apprx. almost instantly !
I will look forward to seeing the results with the new tip.........are you going to test the other new Rocky Mnts ??
