I'm new to C&B revolvers. Cimarron said #11s were right for my 1860 (Uberti on line FAQ said #10s). On first outing I took both 10s and 11s. The 11s literally fell off as I fired (not good). The 10s I couldn't get to go on far enough to clear the frame when I rotated the cylinder. I tried pushing on with a dowel and couldn't get them on far enough. Got frustrated and wedged a knife blade point between the frame and cylinder using the flat of the blade to push the #10s on far enough (I know, not very smart). That crushed the caps so the fulminate went into the nipple and wouldn't fire when the hammer struck it. So far I have tried CCIs #10 and 11, and RWS 1075. Is it possible that Remington #10s will work? Yes, I've read here about crimping #11s but there has to be a better way. I can't believe that a company like Uberti with a decent reputation would make a revolver with a nipple that is sized BETWEEN #10 and 11 cap. Will appreciate help and advice.
