If you don't have a barrel vise, action wrench, lathe, mill, grinders, drill press, reamer handles, etc, you might be better off just sending it to a gunsmith. You can find a smith near you by using Midway's Gunsmith Locator, call and discuss the job with a smith, then once you decide on who to use, ship the gun to them via UPS. Or send it to a barrel maker, some of them offer shop services.
