Getting ready to order a 357 maximum barrel for my contender. Which would be the best route to go on the barrel just let MGM cut the chamber while they build the barrel or have it shipped to Mike Bellm for his famous chamber cut? I talked with Marty at haus of arms he suggested letting MGM do all the work for warranty reason. It will be feed a mix of bullets and some of those nasty J word bullets. Mostly plan to deer hunt with it and use it for range time with buddys.
