It also taught me that the patch do make a difference!
No doubt.
I was using some "leftover from previous owner" .012" patches that by the numbers should fill to the lands nicely, i.e the barrel measured .532/.542 - with the .012 patch, and a .530 round ball, I should be .012" over diameter once loaded.
Tried some .024 denim patches, and it closed my regulation by 2" at 50 yards. A lot more consistent as well.
Go figure.
