My guns love 3" load with CSD wads with Lil'Gun powder and 2oz #T or #F. That made a huge difference, even the 20" cylinder barrel would kill a coyote at 55 yards. The 26" barrel with a modified choke put 18 #T on a paper plate at 40 yards.
Its super messy powder, a lot of powder left in the barrel, im not sure how full of a burn im getting. I dont have a chrono for velocities but the hulls and wads look like they hit full pressure and they feel like shooting the 3" Federal 4Buck, monster fireballs from both also.
I also got some 1/4" 20ga cork wads, its surprising how much of a change those make, I cut them to 1/8" and added it to the 2 3/4", Longshot, BP12 load and it tamed it down a good bit.
