Cayugad, I have the Lee .575 mold and the .562 mold. The .575 with .018 pillow tick is my go-to ball/patch combo for my Green Mountain .58 barrel. It loads tight, but I swab between shots anyway so it's no big deal. I tried the .562 balls with poor results. But all I had on hand at the time for patch material was the .018 pillow tick. I'm sure they would have done better with .022 denim - and probably would load easier than the .575's. However, I never got around to trying a thicker patch.
Here are some comparison 50 yard targets with .575 and .562 with the same load/patch/lube.

I had a long session with the .58 H&A Minuteman yesterday and will be posting a report with comments about ball/patch fit.
