Brasskeeper,
If you like the 330 grain JHP, it was based on the Lyman 457122 Gould bullet. That mould is still available and when cast from a softer alloy (40/1) and loaded over blackpowder, it is a great combination! If black powder doesn't trip your trigger, 5744, 3030, 4895 and a host of other smokeless numbers are available and can give you the same ballistics. I use the Gould HP over black in my Trapdoor and have good success with it.
