Ball Size vs Bore Size

[rickystl]

The general rule for cut-rifled barrels was 10-thousands smaller ball than bore (flats) size. I.E. .530 ball in a .540 barrel, with 10 or 15 thousands patching. I hear this would usually be too tight for a smooth bore load. Anyone's thoughts on this? Thanks.

For a smoothbore you will generally need a ball .020-.030 under bore size and an appropriate thickness of patching.

Rebel: Thanks for the tip.

That's what we are here for. Even in this heat. :: Good luck and have fun.

Ricky,

This would be true if you were shooting a cloth patch, but many shoot paper patch or no patch at all.

You should try looking at:

Bob has good info and you can see the bare ball option. Those of us who do some military re-enacting, see the paper option in a favorable light as well.
