I'm wondering how much 2% increase in FOC would stack up against 6 fps in terms of real world penetration? Everyone talks about FOC . . . . but if it was that big of a deal, I would think we would all be shooting very lightshafts with fairly hefty broadheads.

I was doing a little broadhead testing this afternoon - upped the pull weight 6 lbs.on my Hoyt a couple of weeks ago, and wanted to see what effect it had on the point of impact of various heads. I was somewhat surprised to find that the 125 gr. Muzzy and the 145 gr. Bear Razorheads both hit the same point of impact (20 yards) as the various 100 grain broadheads/field points - even though the spine charts show I should be going to the next stiffer shaft with heads this heavy. I could nock one of these without changing much of anything - at least out to 40 yards or so. The 75 gr. broadheads, however,all hit several inches high at 20 yards.
