So you are using ill fitting caps, have a misfire, then deduce that our claims of reliability are farse? I don't think a cap and ball is more reliable than a cartridge, But they are more reliable than people believe. IF you do your part. I store my revolvers in the house in the safe or pistol safe so as I sad that may be the reason I don't have an issue of them going off 100% of the time. That or it could be how I prep and load them, or it could be that I make sure the caps FIT the nipple. I will run an experiment today. I live in SC so no one can say its not humid around here. I'm gonna load up a .44 cal revolver today. I'm gonna put it out in the Man shed ( no climate control) cabinet and let it hang out there until the weather turns cold, then fire it. Lastly, I bet I burn more powder here than most. I have my own range a short walk out my back door, I shoot at least a couple times a week.
