I had difficulties to find some mica, so i keep it for neck case lubbing, and use Talc (baby powder) instead. Same use, avoid messy touch of alox.
I apply-it sparingly on dry (overnight) bullets.
I use an old t-shirt, put some (few) talc on, drop my quite dry aloxed bullets, fold the t-shirt, take left and right extremities and the movement applied is the same roll than for a yo-yo game (sorry, no better description), just the roll not the throw
.
If bullets looks over coated, i repeat operation with a "clean" old t-shirt to remove extra powder.
After all, chambers need to be cleaned after each range session, works better !.
I rarely shot more than 50 rounds in each gun that i bring to the range, that may explain why i haven't too many troubles.
