Hard to shoot w/o caps. Likewise, seems to me hard to sell percussion firearms with zero supplies on the shelf. Perhaps part of the reason our numbers are shrinking? Manufacturers and distributors need to keep investors' money moving, not sitting unsold in warehouses or store shelves.
So, I bought a couple of tins at (to me) stupid high prices. Demand drives supply. When the demand for common calibers is finally satisfied, for example, not-so-popular goods start to appear. Lately, unmentionable ammo prices have come down. Same will happen with our stuff, eventually.
Dunham's ironically doesn't have any percussion revolvers and few if any caplock sidehammer muzzleloaders, maybe some inlines but they always have 50+ tins of CCI #11's in the muzzleloading section
Cabelas had a case overflowing with Pietta cap and ball revolvers yesterday, 0 military style muskets or rifles when for years, they have always had the usual rack full of rusty Pedersoli Brown Besses, 1861 Springfields, caplock Pedersoli Kentucky rifles . Nothing except 2 flintlock Hawkens by Pedersoli.
Cabelas had very few caps, only CCI #10 and Musket, and I didn't need any other types bad enough to ask an employee to look in the back plus they all seemed cranky.
So, from my observation.....
Repro percussion revolvers are abundant, repro muskets and rifle-muskets are scarce, caps are available varying by Region apparently, and a store a few miles down the road from another may be a Bonanza of caps while another has none
I think the supply chain is catching up and the "resale " idiots have given up for the most part.
Besides the niche market of blackpowder shooters and hunters, no one else cares about percussion caps. It's pretty much 5% of the "firearms enthusiast " group looking for caps , powder and stuff like cast Minies and round balls in "odd" sizes
