The simple answer to the problem of using smokeless in brass hulls is use another type of hull.
The drawn brass Magtech hulls are designed for BP.
Try using lathe turned brass hulls from Rocky Mt. Cartridge Co. Pricier than the Magtechs. They will last probably forever. Smokeless? No problem. Components? No problem, the RMC hulls are true to gauge and use 209 primers.

To be on the wire is life. The rest is waiting.
