What Haggis said. I also usually load from a five round loading block I hang from my pouch strap or carry in the pouch. When the block is empty I 'recharge' it, which is faster than pulling out the fixins for poking in one at a time at the muzzle. I carry a ribbon of ticking and a tin (shoe-polish) of Natural Lube 1000. I open my pouch (the balls are held in a small pocket inside or in a draw-thong bag) drag the end of the ticking strip over the lube tin in my left palm with the empty block in my left fingers, lay it on the block, push in a ball with my thumb, slice off the excess with my small patch knife (held in my teeth between cuts, and repeat until the block is refilled. Once shot, you can't tell the spent patches from precut circular.
Lets see if I can do this. A ball traveling 1,500 fps out of the muzzle of a barrel with 1 turn in 66" rifling is spinning at 16,363 RPM. With 1:48 rifling it would be 22,500 RPM. At those speeds the patch is opening up to centrifugal force and blowing off the ball so swiftly once it leaves the barrel that the shape has little effect.
