For my 8th grade science project (yes its manditory[:@]) I was thinkin i would see which broadhead leaves the largest enrty hole. here are the contestants: Rage 2 blade, Rage 3 blade, Shuttle T lock,Tru Fire switchblade, some old Muzzy 75 grains, and G5 Montecs.I will be getting 10 sheets of paper stacked and nailed into my block and measuring the entry hole. Simple and fun.
