    3F for .45-70 BP PPB

    I've always used Swiss 1-1/2F, and sometimes 2F, for my bore rider cartridge loads.

    Any concerns with using Swiss 3F for a BP PPB bore rider load? Either full case or reduced using a wad stack?

    I haven't had any trouble but I've heard it can cause hard fouling ahead of the chamber. I imagine wiping between shots would take care of that.

    Compression may be different and velocities higher

    I checked the pressure for a 500 grain on a uk internal ballistics calculator. Should be ok, it is for my gun.

    Yep, that'd be a given for both. I noticed both when compressing 3F for .44 magnum BP PPB bore riders.
