80 grains of yellow corn meal may be the ticket for various paper-patchers. If you are familiar with Blackhorn 209 powder, it doesn't work with loose bullets. It was so dysfunctional with my 285 grain Buffalo SSB sabot/bullets, that ignition sounded like I fired a 209 cap.

Anyways, I was using 80 grains of Blackhorn with it, so I double-loaded 80+80 of Cornmeal and Blackhorn (volume measured).

Results were fantastic. Instead of looking for my bullet between my bench and the target 75 yards away, I put the next two about 4" off, at 1:00 of the bullseye.

Walked down to the target paper stand and was thinking I was going to find sideways bullet holes. No sirreeee!

Good luck with your ML adoption.
