Some modern fast twist rifles shoot patched round balls surprisingly well. My old CVA StagHorn with it's 1:32" twist rate makes tiny groups using patched round ball and 70 grains of 3F Goex Pinnacle. The newer Stag Horn guns have 1:28" twist rate . My .54 caliber TC Fire Hawk inline has a 1:38" twist rate. It shoots patched round balls like a dream.
The slow twist rate of the old patched round ball guns allowed for a wide variation of the powder charge without horizontal dispersion when using the fixed sights. This is a good article that dispels some myths and explains some things about the old patched round ball long rifles.

"The wheel weight balls are accurate too."
I never had ANY success with balls that were much harder than pure lead. The guy I shot with said it was probably a case of the patch being unable to adequately grasp the ball. "Some modern fast twist rifles shoot patched round balls surprisingly well." It's easier to get decent accuracy from a slow-twist projectile in a fast-twist barrel than from a fast-twist projectile in a slow-twist barrel. Over stabilized means stabilized, but under stabilized means not stabilized.

Pure lead isn't necessary for good accuracy with a round ball. This target was shot at 50 yards using balls cast from used wheel weight lead. I fired 10 shots, though only 9 are discernible. After my first shot I adjusted my sight picture a bit to get the very nice group shown.
I was shooting a .50 cal flintlock with open sights. I should note that I've never been mistaken for a true marksman. I suspect younger eyes could do better.

As I said, I never had much luck with anything harder than lead...
In MY rifle. Thinking some more about it, based on what my shooting partner said, I wonder if using a different thickness or weave patch material might have made a difference...

With pure lead balls I used .495" balls with a 0.018" patch, which is a tight load. When I switched to wheel weight balls I dropped down to a 0.490" ball and 0.015" patch to make loading easier. That's what I used to shoot the above target. It seems to work. The elk thought so too!
