I took a rifle in to a gunsmith I have known for 50 years because it would not extract the fired case . he was a excellent gunsmith at one time. he built a 1000 yard rifle to use deer hunting. he won many 1000 yd shoots anyway he charged me $65.00 for cleaning it, it still wouldent work so I took it back and it still dident work after charging me another $65.00.. so I took it apart and found the problem and fixed it without any cost.. I found out he had an idiot working for him that had worked on it. so things change over time.. now if I have a problem with a smith the first time I use him I never go back, I don't allow anyone to burn me twice.
