I cast up some .41 bullets the other day (Lyman 410459) and after lubing I rolled them on wax paper that i had dusted with mica. I loaded them into .41 mag cases with 7.0 grs. of Unique.

When I went to the range and fired them I noticed that the cartridges were getting difficult to chamber in my Blackhawk. Not a problem I had ever run into before trying the mica. Well it was worth a try, it sure made the bullets easier to handle as they didn't want to stick together.

what was the lube? Did they eject easily after firing? What diameter did you size them to? I bought a .38 revolver from a guy that the chambers were so clogged with lube the rounds refused to chamber. Thought I'd got stuck on that deal. Almost sent it back to the factory when I noticed some lube on a few cases that ALMOST fit. HAd to wire brush each chamber to clean them up.Now it shoots and ejects fine.

Hello all,
Argonaut, what was the reason for the MICA,
if you don't mind my asking?

What I did with mine was I put some MICA in a Margarine dish poured in some bullets and shook it around. Then I plucked out the bullets with some duckbills and repeated.
My reason for dusting my bullets with MICA was to polish the bore of my guns so the barrels wouldn't lead up shooting cast at jacketed velocities.

It worked great. See:grin:

Happy shooting

I put a very light dusting of mica on my cast bullets and have never had any troubles I am shooting them out of a contender and encore

the reason I use the mica is to keep the bullets from sticking together

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.
