Try AA5744. Accurate Arms says it was developed in large black powder cases. It shoots very well in 45/70 and with cast bullets in 30-30, 308, 30-06, and 303 Brit.

It is not position sensitive, all my chronograph data was shot standing. I lowered the muzzle, dropped the round in, and raised the muzzle to shoot.
