I Have a Umberti replica 1860 Army.While I like the gun and it is quite accurate, it has given me fits with the fired caps falling off the nipples and down into the mechanism when the hammer is cocked. This happens with both #10 and #11 caps. I thought this might be due to hammer lift so I replaced the mainspring with a replica for an original Colt Army from Lodgewood and fitted it which made the hammer a lot stiffer to cock. I also replaced the nipples. The problem persists. The charge is 21 grs. of 3f and a round ball, well below the service load. Was this a problem in the Civil war or were caps stronger then? Modern caps look like stars after firing. Any help would be appreciated. Thanks.
