I regularly take a vow that as soon as I've shot up the last bunch of odds and ends of percussion caps I got a "good deal" on, that I'll permanently switch to CCI No. 11 Magnums. Inevitably, another "good deal" comes along, and I'm back to shooting up the remainders of this or that.
Recently I got another "good deal," which included several unopened cans of Remington No. 12 percussion caps. I should be able to shoot these in my Pedersoli muzzle loader, as all my shooting is at the target range and there is little danger of the cap coming off. Obviously, they would be hopeless in cap and ball revolvers, as they are too big, even with pinching the sides. They might even fit over a musket nipple, though I haven't tried one yet. If there is more priming compound in them than in a No. 11, that would be all to the good.
Does anybody know what these were for originally? I can't find anything about them On Line.
Thanks in advance.
