If the crown is smooth, there will be no cutting, even if using a double patch.
In my opinion, the group shape and size is meaningless, unless the ball and patch
combination is optimum.
By this, I mean, if there are problems with the patches, ie: cutting, scorching, burning
as in failing to seal, then the groups are meaningless.
I would concentrate shooting at 50 or 60 yards distance, until the groups look more like
this, then, go out to 100yards to fine-tune the load, as to powder charge and accuracy.

These groups were shot with re-claimed patches, originally shot from my .69.
Too, these groups were shot after the barrel had been shortened, some 4".
