Went to a gun show last weekend and picked up a Richland Arms percussion rifle...just because it didn't look too bad and was cheap. It sat around here for a few days, and I broke it all down and cleaned it all up and did some minor repairs. The barrel looks like it should shoot okay as there isn't any pitting in it. I tried popping a couple caps just to make sure the flash channel was clear, and it took two drops of the hammer on each one to make them go off...so I am assuming the lock spring is too weak. I thought it felt a little weak, but this sure confirmed it. Anyone out there have any idea where I could find another spring? I know the company went out of business in the 80's, but thought maybe someone would know of a source of parts for one.
