Thread: Fireforming case with cleaning patches and pistol powder

No mess at all, the wax vaporizes.
Will work fine on the .243AI. You cant put enough trailboss in a case even with a heavy bullet seated to get any kind of dangerous pressure, youd be lucky to get 1200fps with a 100gr bullet with a full case of trailboss. Not the case with pistol powder however, about 10gr of AP70 or similar would be about the same pressure as a full case of Trailboss. In the .243 case that's about 14gr.
