Now, I havn't done any of this. But I Have been reading a lot of different post about the 450 Mongo loads made from the 444 Marlin brass.
Then I read another post from a fellow who bot from Midway, brass for the 9.3x74R cartrige (which the rim apparently fits the T\C 45-410 much better than the 444). But to get this 9.3x74R to streach to 11.4 x 74R, some annealing, shooting and other work must be done.
To "fill" the long cartrige, after the powder is loaded, a shotshell wad is inserted prior to the bullet seating to keep the powder in a contained area.
However, I was wondering if anyone had given any thought as to using the new trailboss powder in a cartrige such as this. This new powder is designed for mid-range loads while taking up a bunch of space in the cartrige.
It doesn't change the work on the brass, but maybe the work on filling the empty space in the brass and perhaps the saftey of the load?
