I have to tell y'all it weren't easy getting my Bow sighted in. Took a couple of hours, i gotstid 23 2219's and 2 practice B'Heads. I tried them on all 23 and wrote down where they be hitting on 3-D deer. Only 3 hit in 1 1/2" of 1" red dot painted on deer. I hand spun every arrow an those 3 were sweet. Of course they be the only 3 that be same weight and same size feathers, flat noks and inserts and wraps. All the rest be different weight and vanes an such. Its all a part of seeing what works fer ya an yer Bow![][:-]
