Has anyone ever tried this ? Seems a little desperate /extreme.Cast Boolits forum.
I did it a couple of decades back, not out of desperation though.
Like others here commented they just wanted to try it and see if it worked.
Reloading the rimfire ammo, was my big concern as I had several antique pistols that required rimfire ammunition that was almost as scarce as hen's teeth. That priming compound has been around for a long time, specifically for the purpose I needed it. I also went so far as to purchase a punch and die to cut tin soda cans, back before the days of aluminum soda cans, and form the striated discs into primer cups. I needed to save the anvils from spent primers to insert into them.
I don't know what this newer product is like, but I used t have wet the old mixture with a bit of water to make it into a paste then almost fill each cup and push in the anvil. They had to set overnight to make sure they were dry. I usually left them open for 48 hours, then used a dab of extremely thinned down fingernail polish over the open face to keep it dry, from atmospheric conditions while in storage. I did the same with the rimfire ammo I reloaded, usually with black powder. I also sealed the primers into the pockets with fingernail polish, just in case.
When push comes to shove, you can do the same with the compound on match heads. I tried that also but it wasn't very consistent.
I believe the new priming powder mixture is very similar to that used in making match heads, potassium chlorate and sulphur with a binding agent and a wetting agent. I don't know. I haven't used or seen it in a few decades.
It hopefully contains other ingredients to keep it more consistent and likely burn hotter.
