After watching their video I have to ask:Update: Earlier in the thread I said I would make some percussion caps and try them out.
The dies performed great. The percussion caps are ugly. If you are a perfectionist and everything has to look pretty then this is probably not for you.
I made 20 #11 caps. The following day I mixed one batch of primer mixture and just had enough for the 20 caps. I used 3 drops of acetone to set it and gave it over 24 hours to cure. Probably more like 30 hours but 24 was required.
Today I tried them out with live loads in my Traditions .50 Trapper. My observations were as follows. They fired great. They did dirty up the outside of the gun, more so than the commercial caps. The area around the nipple was the dirtiest and had a rust appearance. I had one cap go off but did not have enough power to ignite the Pyrodex. I replaced the cap and had ignition. I noticed a couple caps lost the powder adhesion in the cap.
So in conclusion I am very happy with the cap makers and primer mixture. The couple deficiencies that were there I would say they were from human error. Am I going to stop buying the commercial caps? No, I will use them for hunting where human error sucks. I am primarily going to use the homemade caps for shooting in the back yard.
Keep in mind the #10 and #11 cap makers are $50.00 each and the priming mixture is $20.00 and you are supposed to get 2000 caps out of it.
Would they work for Revolvers?
They look like they may not have enough grip to hold on with five recoils...?
