Cylinder pin fouling up

[Turnup]

Is the fouling is getting in from the front of the cylinder?

First thing to try is to liberally apply a heavy grease to the arbour pin and to the aperture in the cylinder. This might help to keep the crud out.

Not familiar with the exact configuration of this gun: Some have a protrusion at the front of the cylinder where the arbour pin passes through (like a bush proud of the cylinder face), so that the escaping crud from the gap between the chamber mouth and the barrel cannot easily get to the pin. Is there an excessive gap at the very front which is allowing space for crud to get in? Would a thin washer in there help to plug the gap?

Does the cylinder have a lot of fore/aft play when on full cock? (there will be a little)

Keep it greased up with a thick grease.

Silicon grease is not affected by the heat.You could try that.

Me and another black powder shooter have started making and using paper cases (perming papers rolled then glued using a prit stick) I just put black powder and fine semolina in the case but he puts the ball in as well) we have both noticed that fouling is reduced when using paper cases.

Thanks for the replies, not a lot of play other than what I would expect and not enough for a washer.
I shall try the grease and keep you posted .

You can use hand rolling cigarette papers as well. Dip them in a solution of saltpetre and let them dry.

We found the perming papers don't need saltpetre on them as they burn a lot better than fag papers

Thats interesting I must give them a try.

As with the fag papers, you have to work out how much to cut off to prevent the paper doubling over (laving just enough to glue)

The copper grease worked a treat, shot 2 cards, 13 on each and the pin came out with very little fouling .
Thanks for the suggestion.
