For those of you who have cap making dies

and speaking of video's, this was of interest to me as well and possibly to those making caps... https://www.youtube.com/watch?v=PIJng_vnz7U

have you ever thought of a grain or two of black powder mixed in? I have some old white tipped strike anywhere we found and was curious about this. They still seem to strike so I'm wondering how it'd would work as a cap primer.

Thank you... I'm new at all of this so your comment is to me invaluable..

Aloha..

I have not tried mixing in a little black powder. I would but I don't have any. I have read somewhere that magnesium also raised the flash temperature and if I read it correctly, helps to neutralize the corrosiveness after firing. As soon as I get some magnesium I will be trying that. Or maybe some aluminum magnesium alloy ground finely. And just a fyi about aluminum and magnesium burning and raising the flash temp: I used to work in a auto garage-speed shop. The owner was into racing dune buggy style VW's. He often was machining aluminum and aluminum magnesium and he had some magnesium shavings too. We had a big home made wood burner (Wisconsin) that you could actually crawl into. He would occasionally "throw in" to the fire a handful of aluminum or magnesium shavings. To explain it simply, that is what the fireworks guys use for the bright sparkle in fireworks. It really lights up when you get enough oxygen into it.

Not as dirty?

I just got done shooting a dozen 22lr reloads. I used some aluminum powder along with roll caps in the primer. It may be a coincidence but the barrel of my gun afterwards looks much much less dirty. Could the aluminum be causing that?

 

[midland man]

so traffer how accurate is those 22lr reloads??

I don't know. I shoot them in my sisters garage to test them. I am only shooting about 20 ft. And the bore is worn out on my test gun. The last time i was on the range, it appeared that they were a little more accurate than factory loads. BUT that was only a few shots. I have been experimenting with different hardnesses of lead and different styles of bullets also. Once I get things dialed in I am going to test the accuracy. (probably not till spring when the range opens again.) i was shooting loads with 2 grains of powder today. They seemed about even with factory ammo, maybe a little lighter. I am going to try 2.25 grains next. I think from what I have seen so far, I am going to end up using 2.25 grains of powder. a 35 grain slug of 8 to 10 BHN hardness. And put a little aluminum in the primer. Once I settle on the load, I will work on consistency to get accuracy.

Armstrong's mixture is the compound in question. It is readily google-able, and fairly easy to make. Just be careful, and work with very small amounts. Please.

That is correct. However adding things like aluminum or black powder are not elements of armstrong mix. And Armstrong mix is a term used now a days for recipes that can differ quite a bit. I have read many articles about it especially the safety factor. I might post some of them as they tend to raise awareness. I have been discussing reloading 22 rimfire in several posts on THR I always warn people about the dangers of the primer or "armstrong mix"
