Fireball2, is pretty straight forward loading shot in the 375.
use 410 data as far as powder/shot ratio. drop powder cover with a cork wad 1/4 inch thick drop shot, cover with a 1/4 inch cork wad and roll crimp. deadly grouse load. have done the same in my 41 mag for years. dropped a grouse once and everybody thought I was a deadeye.lol
Outstanding!
