trying my 1849 and a Uberti "Wells Fargo"

one shot each. It took trying 8 caps and each of these were loaded with 2 rounds each but they did not fire AT ALL on the first 4 caps I tried from an old Alcan tub. then on some older #10 CCIs the 1st cylinder on each did. As I once said: I have that kind of luck :(

Addendum on the 1849 (not sure about the Wells Fargo): looks like I have a weak hammer spring. I tried it with Alcan, Winchester, CCI, and Remington caps and none work. I am ordering a new spring
