Cap jams are typically solved by handling, not shooting as if it was a modern cartridge revolver. Also, nipples are tapered now so upgrading from factory is a great idea in addition to a better main spring. Springs are not as strong as they used to be, especially Uberti. 25+ years ago caps were made thicker, heavier and never blew apart causing jams. More often than not they had to be pryed off the nipples after shooting! Rolling the caps with even pressure and seating them properly works with these cheaply made modern caps. But a mid 19th century percussion firearm will always have cap jam possibilities. Not Handling it like a modern revolver typically solves any issues. I Like the channel, may need to subscribe.
I’m with you on the smaller hole nipples but the original hammer springs I’ve seen were way stronger than the Uberti stamped sheet type. That prevents originals from most cap jams. My several uberti’s all benefit with much stronger springs.
Adding or using a heavier mainspring helps with the blowback but causes other issues as the cap binding the area from the hammer to the recoil ring /discharge shoot area. A good smoothing of said area with a ceramic stone has helped but not rectified my binding situation. @@earlyamericanarms7303

Przewierć z boku kominki aby pozbyć się nadmiernego ciśnienia powrotnego. To powinno zabezpieczyć przez zacięciami.
I believe your powder charge was a bit stiff; thereby, creating cap jams …
After doing some research in an old Dixie Gunworks catalog I backed off to 15 grains. It shoots a lot more accurate.
Interesting comment Steve, I hope that indeed solves the jam problem.
