Pahoo I had a similar problem with a CVA Hawken and it turned out that my method of cleaning was the problem.I used a bucket of hot soapy water and after removing the Nipple I used the tried and true pump and scrub to remove fouling after drying I replaced the nipple lubed the barrel and put the rifle away.After a time I noticed that I was getting hang fires.I removed the clean out screw and found that there was a moderate amount of carbon build up caused by lime from the boiling water used to dry the barrel ,the lubricant and the residue from the primers.This build up was causing the flame from the primer to defuse and cause the hangfires check your Bobcat it only takes a very small amout to cause a problem ELMOUSMC
