i'v read most of the topic, i have been shooting c&p revolver for close to 35 years, never had problems, 3 things i do 1, one hand hold, just in case. 2 lube, lube, lube,. that is wad lubed, ball lubed, and then, after cyn. loaded, small amount, or like some i know do, fill the thing up with,(i my self do not do this), bacon grease. or another lubed wad. 3 look at each cyl after each shot, (i am in too markmenship, i wish i could spell, it's about the same as my shooting.) not to be on soapbox, back too the topic, look at caps i do this on the up hammer pull, best i can tell ya, the action on witch the hammer is cocked barrel up, thus if a cap is loose it will fall off i'v had this happen :hmm: cant count, yes caped pinched, right size, hot load? never know,cease fire replace cap, fire some more.
