So I picked up 500 CCI #10 for my soon to be here Pietta 1858
I also picked up a new spare cylinder at the same time.
I just tried the caps on the new cylinder and they are to small, only go on about half way ???
My old Piettas took the CCI #10 perfect.
Kind'a bummed seeing how caps are so hard to come by.
Should I change the nipples to another brand or try to find some #11
