After messing around with numerous jigs and rigs racks and ideas on how to efficiently and quickly coat those itsy-bitsy tiny little boolits, I have finalized the best and most efficient method is DT for my proposes.
Using the standard CoolWhip (#5) bowl, put about 1/3 tsp of red powder in on top of a handful of boolits (~50), enough to cover the bottom, and start swirling.... NO LID. Add powder sparingly as they coat up. Those little 223's really coat fast! 30's are just about as fast.
When coated.....GENTLY (!) sift them out onto 1/4" hardware cloth wrapped around your oven racks. Put a piece of paper under to catch the extra powder. Let them gently fall on the wire mesh, keeping them from clumping as much as possible. Nice thing is, you can just put your NS foil right over the top of the hardware cloth to do your other larger boolits! Works perfectly as a sub surface for the foil. You will eventually have to put new cloth on, but the roll I bought at Lowe's will make a lifetime supply of rack covers!!!!!!
You are now ready to bake. I have been able to get at least 150+ 223's on a rack at a time. 10 min and 400F later, you have nicely coated boolits...even the bottoms and GC areas.
To remove easily, put the full rack (boolits down) over a cake pan with a towel on the bottom and, using a small flat ended-dowel, gently push the still hot boolits off the mesh.
This method eliminates all the washers, nuts, wires, O-rings, and other methods I have tried to hold these little dudes. The coating is ~90% as good as ESPC. Since they are so light, they do not knock off the powder from collisions with the surrounding boolits as larger cal's do.
Simple, fast, and efficient. I coated the red ones last night in only 2 bakes. There are about 400ea) 223 Bators in that picture.

If you want to use GC's you can tap them on with a hammer after PC and seat them in your press. I feel that PC'ing over a GC is not necessary. If they do not fit with friction, you have something undersized on your boolit or oversized on your check. All the ones I just did are for 22LR replacements and will be loaded for around 1000fps and without GC's
The yield is around 95%.....those that have lead showing thru on the TOPS of the grease grooves (ONLY)....... I just coat them again!
Just another idea how to easily & quickly coat those pesky very tiny boolits we all love and enjoy shooting without spending lots of time and effort building jigs and racks and rigs.
