@Texastothecore,
While I have not measured the particle size of the glass powder I am using, it is about the fineness of flour (my guess is 100 mesh or smaller). I have used a little coarser material in past primer formulations and it works well, but I was worried about barrel abrasion. The finer powder should be more like a polishing agent than an abrasive.
@Rustyleee,
"Check this out... compound kit.

Hey, I have that kit and have reloaded and tested about a dozen 22LR rounds so far. I have used the original Eley Prime mix to prime the cases since that was designed for rimfire cartridges. The combination bullet mold/crimp tool works OK but the quality is not stellar. I am looking at assembling an equivalent set of tools, but with higher quality components. For example:
1. CH-4D makes a superior 3 piece 22LR die set for ~$103, the shellholder is another $12,
2. Lyman gas check bullet mold 225438 will make a better bullet and has been used by several folks on castboolits for making black powder 22LR rounds. It costs ~$73, add $33 if you need a set of handles.
3. The most useful part of the kit to me is the small funnel. The exact same funnels are available from eBay, 20 for $10 (free shipping too).
So for about the same cost, you can get much better tools to do this job. Finally, my tests at the range have been 100% successful so far. I used a loading of 1.5 gr Bullseye which seems to be a little hotter than standard target ammo, but not by much.
@Oreo,
I apologize if you thought I was criticizing you about mercury fulminate based primers. While I obviously am willing to take some risks in making primer compounds, this particular compound exceeds my risk threshhold. Anyone who makes and uses this compound needs to do a lot of reading beforehand and take all needed safety precautions to avoid getting seriously hurt.
