Dave, that's good news and great that Henry stepped up. I have a Rossi R92, 44mag with 24" barrel who's bore is very generous. So generous that it needs .434" cast boolits. Unfortunately a loaded round is too fat to pass between the load gates. (you have no idea what a pain it is to try and get a too fat wedged round out of there.) I contacted Rossi and they said their guns are manufactured for jacketed ammo... A BS response to be sure. My Rossi R92 in 357mag loves cast.
