Development of PP loads for the .44-77.

[Distant Thunder]

Arnie,

I did try the smokeless and COW idea and it blew out the shoulder on the very thin Bertram .45 basic brass and only the shoulder. On any of the thicker brass, the Jamison and my converted .300 Win Mag brass, it did even less. I quickly concluded that if I was going to have to fireform a second time with black powder why bother with the smokeless fireforming. I think a bullet is required to get enough pressure. The brass has to expand out a bunch to fill the .44-77 chamber.

I am exploring another option this morning. I'll let you know.
