    I'm trying to find what size round ball is used in a 10 ga BP shotgun. I know the bore size is .775 I suspect it is @.750. Anybody know for sure. Also wondering if anyone knows where you might be able to get a mold for it.

    If your BP shotgun is an older one, it is not made to shoot a single round ball. They are made to shoot bird shot or buck shot at low pressure. If you cram a single round ball down the barrel with a patch, you are likely to bulge the barrel....or worse.
