I think it is probably this type of shot cup but am guessing as I do Front End Stuffing shot gunning.



But here is the link to a suggested shot cup.

However it might have been a shot cup with the piston ~


I suggest to use the solid shot cup as using a shot cup as pictured above with the cushion or piston on the bottom one has a tendency to 'crush' them when using a ram rod which results in poor patterns.

And you need an "over the shot wad" too such as suggested by Lemoyne! Other wise if you tip the gun a bit yer Bb's drool out!

And if you are looking for Wads
The link has a huge selection some dry and some lubricated. For lubrication I just use crisco or bore butter.

Typical Black Powdering shotgunning I use a over the powder wad - (is like a fiber board) which is lubricated then a shot cup or maybe not. But shot cups can help control the pattern and then a thin over the shot wad to prevent the shot from falling out. So down the barrel in thsi order goes ~ Powder, Wad, Shotcup, Shot, Thinner wad.

When playing around with my shotguns I use equal parts of powder to shot. So 80 grains of powder would be 80 grains of shot. From there I adjust up and down to develop a pattern and then try different ranges. I bet you can get at least 30 yards with good success.

On a side note though - I have never used a rifled ML to do this they all have been smooth bores.
