Just to follow up on post #17:
The only printed Dixie Gun Works catalog I have on hand is #160, from the year 2011. On page 634 is a chart which shows bore sizes (land to land) and recommended ball sizes for reproduction guns. They list the Hopkins & Allen .45 caliber rifle (which used a Numrich barrel) and show a bore size of .443", with a recommended ball size of .435". I don't see groove depth shown, but I'm certain that these barrels were intended for patched round balls.
Buffalo Bullets used to make swaged round balls in .435", but these may be hard to find now. Most shooters are happy with a ball .010" under bore size, which would be .433". To satisfy my own curiosity, I looked around a bit and found both Hornady and Speer make swaged round balls in the .433" size, and Lee does still offer a .433" mould. Track of the Wolf currently has this mould and .433" cast and swaged round balls in stock.
Best regards,
Notchy Bob
