I can’t answer for him, but I can say that many (including myself) find smoothbores shoot just as well with bare ball. “Chewed” ball is another option. Additionally, some folks eschew the patched round ball in smoothbores because there isn’t really evidence to it being done in the period when these guns were new technology. I enjoy using gear that is historically documented and in the manner that it was used historically.Why don't you patch your round ball?
What kind of charge are you using ?JimB,
In my case, I don't patch these balls because they are too close to bore size to wear a patch. (.750" ball, and .760" bore.)
Bill Curtis used this combination and did very well at National and I believe International shoots with them. In the timed events he participated in, he had time to spare, whilst some using patches really struggled just to finish in time.
If I had a ball mould that threw a smaller size, I might try a patch, but rifles are easier to load patched than a smoothbore very often.
A good pal back in the UK uses patches and a lesser charge, and can shoot scores in the mid or bit higher 90's in International matches. I think it also comes down to practice! LOL.
The load I use is;
Powder, a thick felt wad, (this forms a nest to hold the ball central on the way up the barrel)
Ball, a good big gob of lube, (I use Udderly Smooth,(Wally world for one))
Lastly another thick felt wad. (This hold ball firm in the bore of course)
Wads are at least a half inch thick, cut with a ten-bore arch punch. 3/4" thick is better.
