I've been hunting with carbon arrows with Wenzel Woodsman 125 grain solid steel broadheads which weigh around 430 grains total and have a FOC measurement of 16%. I've been reading that the ideal FOC for hunting arrows is around 9%. Would adding weight to the nock end of the arrows possibly improve their flight consistency (grouping), with which I have problems, assuming that their spline was heavy enough? Would this increase or decrease penetration?
Have no idea but I would put this post in the technical section. Not going to get to many responses to it here in the "Introductions" section.
