Iv got a Lyman mine mould and it didn't shoot well in my 2 band at all. It was fine with patched ball though.
The 2 band went and iv now bought a Parker Hale Musketoon so will be re trying them with the shorter barrel
once my ticket comes back and i can take delivery of my new toy. If no joy i will stick to patched round ball
as before.
Tac has covered it all really. The only thing i would add is never be tempted to dry fire onto a nipple cover.
I did it by accident and it shattered into lots of tiny bits, DER!!! Tim.
