I've finally gotten down to my last pound of SR4756. I primarily use it in 12ga Buckshot loads, see here: https://castboolits.gunloads.com/sho...for-4-Buckshot
I don't shoot a lot of shotgun, but it'd be nice to go ahead and pick out a new powder. Anyone have any suggestions for a good substitute? I see lots of guys using Longshot, Lil'Gun, and HS-6 these days. I used to use a little Blue Dot in my pistols, and might have some on hand, but that seems like I'd have to adjust my shot column to use the recommended dosage for buckshot loads. The great thing about the SR4756 was the relatively high velocity for pressure. Lyman's manual shows the 27-28grs of SR4756 getting about 1250fps in either #4 buckshot or standard 1-1/8oz shot loads while only developing 9000psi.
What do you recommend?
