reloading pinfires
I reload my pinfires with percussion caps for the primer
and mostly round balls and BP. I pull the pin up, I take
the old primer out (looks like a percussion cap), I put a
new percussion cap in (cup up, pin in side it) put the pin
back down, sometimes a spot of glue on the cap and/or
pin, than black powder and in my case a round ball.
As long as the cartridge is fired in the same gun it will/should
go back in the same gun after reloading. If you did a lot of pin
fire loading, sizing dies are not hard to make.
