Brownells USA I will buy this product again and again 06/12/2011

Bore was beautifully finished, .0001 straight from end to end. Groove diameter was a few 10ths under bullet diameter and .0001 taper from breach to muzzle, (3573 – 3572 @ muzzle) giving excellent gas seal! Best 35 cal barrel I've seen yet!
