I've got a rebarrel idea that I intend to pursue at some point: Browning A-bolt Super Short action chambered in 450 Bushmaster. After searching the innanet quite a bit, I've gleaned that McGowen in Kalispell, MT will rebarrel A-Bolts, and has a Bushmaster reamer. They are actually the only place I've found online that meets these criteria.
Anyone have work done through them?
Maybe someone has a lead for me on other places that fit the bill?
