I shoot 85gr. 2F in my 20 bore Hunkeler smoothbore with .022" patch and .595" ball.
My other bore gun is a rifle, of 14 bore (.69) for plinking I use 82 to 85gr. 2F and .034" patch and a .682" pure lead or .675" harder alloy round ball.
For hunting with the 14 bore rife, I use 165gr. 2F GOEX, 1st shot is 682" ball, Track's Mink-oiled patch. 2nd and/or subsequent shots are with a non-lubed paper ctg.
having 165gr. GOEX 2F, a Hardened .683" ball.
These were a light load for the Bess, having .715" ball and 85gr. 3F, but you get the idea. Tapered paper ctg. is easier to handle and always sit in the pocket, ball down.
They are very tough, 2 wraps and can be carried in a pocket all fall, without damage. With no lube, they do not pick up any dirt or lint.
The paper ctgs. for my hunting 14 bore rifle, actually engrave the paper upon loading. A short starter isn't needed, but you then have to really choke up on the rod to get them
started. Then down they go, easily. They give identical accuracy to a patched round ball with the same load and shoot to the sights, same deal.
I can fire 10 of these with no loss in accuracy, but then I have to shoot a cleaning load of a wet cloth patch and pure lead or alloyed ball. I use my plinking load or 82 or 85gr. 2F
(whichever measure I grab). This load with spit lubed (very wet) patch cleans the bore and allows another 10 shots to be fired.
R. Blevins, a member here, tested paper ctgs. down to .54 cal, and found that was the lower limit for accuracy with them. Smaller, as in 50 cal and smaller, seemingly develop too much pressure
to be accurate with paper ctgs. it seems.
DPhar and Roger both found the same as I did - same accuracy with the ctgs. as patched round balls. They are worth trying if interested. Bob-in-the-woods also sued paper ctgs. to good
effect for hunting with his 10 bore.
