A few guys use Trail Boss in our club single shot rifle matches, bullets go so slow you can see them fly down range through the spotting scope. None score well so I dismissed it as a useful powder for my purposes. The Cowboy shooters like it because it’s bulky and they want very low recoil & velocity.
Seeing your question and curious searched the web for Trail Boss & Shotgun. Internet consensus is it’s too bulky to use in shotshells, can’t get enough in the case to produce adequate velocity. I don’t always trust internet advise.
Like you I load paper hulls with black powder & stacked wads, think it’s a ideal propellant, all I use in my Lifter. Don’t think I would try Trail Boss, Black easily available and works so well. Somebody has hard data Trail Boss, pressure and velocity, could change my mind. Velocity under 1100 FPS would rule it out for me.
