Hi, I've got a few Pietta and Uberti Colt replicas, but lately when I shoot, I can't seem to get more than six or seven shots before the cylinder is too 'sticky' to revolve by just cocking the hammer. I see videos of guys shooting and reloading for 30 and 40 shots without cleaning. I'm using Pyrodex P, .451 round balls. No wads. Am I punishing myself by not using wads or lube over the balls?
