I have 7 of whats left of 12 of the BH Vapor 4000's from 4 years ago. So far I have taken, 2 bears, 1 Gold Series Catalina Ram ( 1-3/8ths short of World Record at that time), 20+ deer and I can't say any more better things about them!!
I shoot them from a Mathews Q2 at 65 lbs, LumaNocks, 2-1/2" Bi-Delta Vanes and 100grn GrimReapers for a total weight of 425 grns.
