Yup , quality control of North American broadheads suck . in same pack you can have up to 20 gr difference from one to another .
i had a customer a few years ago who was testing broadheads as he was going for Cape Buff and wanted to us the beat broadhead he could find .
bought 39 silver Flames to test with all the rest , sent me a spread sheet of what he discovered and i was amazed at how many top named heads he had Crap written after , not sharp , fell apart , weights way off , bent on impact .Silver Flames were with in 1 gr of what they said , he got his Buff ---- herb
