When I first started hunting with my .54 renegade I used those water proof caps. I read to pop 1 or 2 caps before loading. While on my stand it started raining hard. I got soaked and it was cold, After getting down I was going to discharge the renegade before I went home to change so I could load a fresh charge. It would not go off after numerous caps. I went home and took my nipple out and noticed I could not see thru it. I took a small wire and poked it thru the nipple, out came two small cards from the caps I popped that morning. That afternoon before going home the gun fired fine. I quit using water proof #11 Caps.

One other time I was shooting my renegade at the range, all of a sudden it started misfiring and FTF. At home I looked thru the nipple and the flash hole was oblong. I replaced the nipple and never had another problem as yet.

Recently I was at the range and while swabbing between shots I probably got a patch too wet, I had a FTF. Now I make sure all my swabbing patches are barely damp.
