And it’s not just the pressure at the port - the action also needs enough gas volume to function. Most BD loads use about half the charge weight of “normal” propellants, hence half the gas volume.

I’m not certain if Lil’Gun is a good choice for reduced loads. While it may work great in high density .221 FB loads, similar charge weights in a much larger case may not work so well - or they may. Many ball powders don’t do well at low charge densities.
