Don't be afraid to shoot real gunpowder. You will be amazed what can be done with it.

Glenn,
I am going to be loading for a German .450 Long double rifle. This basically the .450 BPE with a bit more case taper. Early coiled brass case dimensions.
The Nitro for Black should be "easy" with the data available from Sherman Bell.
Getting it regulate with blackpowder might be more of a challenge. I don't want to give up to much bullet weight to get the needed velocity.
