Thread: Reloading brass hulls for an English Black powder s/b/s 12 gauge.

old rule of thumb for black powder...equal VOLUMN powder and lead shot........
wee dab of nail varnish will hold better than wax.

you need uncrimped case to fit in chamber with no resistance BECAUSE it needs room to unfold so payload can smoothly get past it....a 3" unfired shell will fit in 2 3/4" chamber..... your trial of 2 3/4" NOT fitting sujests you are correct with 2 1/2"
