hi all, i'm looking at building up some .45 lc shotshells for snakes or the occasional close squirrel. this will be shot out of a revolver. i'm thinking either .410 shells or .444 marlins cut down to 1.5 inches, about 160-170 grains of shot with card below and above it. where i'm having trouble is what powder to run. i don't want the pressure going crazy but it can't take up very much space due to the large space the shot will take up. i was thinking a light load of unique would be the ideal, but i keep questioning myself. i'm not sure what powder they use in the old remington .410 but there was 14 grains of it. if i cut that back to 8.5 grains it's right at the edge of the brass leaving room for 160 grains of shot. the .410 runs at i think 12,000 cup, so that might be a good powder to run, unfortunatly i don't know what powder they put in them. any help would be very much appreciated.
