maybe i've missed the point entirely of dr. ashby's paper. i have read it several times and i agree with sylvan in that i thought dr. ashby's paper was making the point that ke played a small role, but was emphasizing the broadhead's design was more critical in penetration...have i missed the boat?

by the way, i agree with gibblet on this one...i've also taken calculus-based physics in college. although i am not a research engineer with 30 yrs experience, i don't think sylvan has posted anything that is incorrect...he is just repeating laws of physics.
