12.7 x 44r bullet

[Buzzard II]

Hi,
Has anyone successfully used a RCBS cast bullet 50-340 SWC 50 Action Express (.500 diameter) 340 grain semi wad cutter as a bullet for the 12.7 x44r Rolling Block.? How did it perform.? Which brass did you use.? Any help would be greatly appreciated. Thanks
Bob

Not sure if this topic belongs here or under another title.?

Might post under single shot rifles or black powder cartridge.

PS several of us use the .500 S&W bullets in .50 muzzle loaders.
