Thread: 44 mag loading for rifle

Hey guys, new to re loading this cartridge and thought I’d see if anyone has some good advice.
Will be used in a break action single shot with 16.5” barrel only.
I have plenty of ADI AP50N that I am hoping to use. The manual says AP70N. But has anyone used the AP50N for loading 44mag?
Wanting to develop a sub and a supersonic round. Thinking of using cast semi wad cutter bullets.
Any help and info much appreciated. Cheers guys.
