RSTShotshells are good people but I have wondered for a very long time what is holding them back to the extent of their shortage.
It's easier to get low pressures with larger bores and part of the trick to getting low pressure is lighter shot charges and lower velocities.
Perfect Pattern is a widely available powder so is Longshot and Win 572 along with Cheddite primers.
6600 psi at 1200 fps with 7/8 in 12ga using PP powder, Ched primer and Rem Gun Club hull.
7500 psi at 1150 fps with 7/8 in 20ga using Winchester 572, Ched primer and Federal hull. Use 3/4 ounce and pressure goes down and fps goes up.
