It's been a nightmare to get this one right. Many technical problems to overcome. That said, I'd rebarrel one of these again and just put up with the challenges involved. The ever present option for you would be to send the gun to Bob Hoyt (barrel magician) and have him line it or bore it to your spec's. Since you know your boolit weight, he could give you a twist rate optimized for it.
