New to the forum, but I have two Renegades and never a problem with them. Cleaning is hot soapy water, then a good hot rinse. Dry patches until I'm satisfied and a light coat of oil. Then 24 hours before I 'm going to use the gun I take it out and store it barrel down on a paper for any oil that has pooled at the bottom. Run a clean dry patch down the barrel once again. Take the gun outside and put a fresh load in it. Pull the nipple and put a small charge of 4F behind it. Replace the nipple. (incidentally I also put fresh nipples on after the cleaning). Once I get to the field I put my CCI cap on and I'm ready. Gun goes off first time every time and every time after too.
