[QUOTE="Sgt Dog, post: 3935312, member: 15840"] Just be caseful of pressures. If the rollstamp (left side of the receiver) is a two-line rather than a three-line, it is a ‘cast’ rather than ‘forged’ receiver. The burn rate of your powder is critical to pressures. IMR-4198 is pretty good for replicating black powder pressures. Some go by a 40% rule. That would be 40% of 20gr black. I have found black powder velocities are reached well under 40%. Shoot me a pm if you ever want me to dig up notes. [/QUOTE]
