So, as the title says, my model 60-7 Smith has ignition problems. It will shoot Federal primed ammo all day with no problems at all. But CCI primed ammo is literally hit and miss. Usually at least one or two rounds each cylinder full will not go off shooting DA. If shooting SA they go off at least 95% of the time. I know CCI primers are harder than most. Yes, they are my reloads (been reloading for 30 years). But these rounds go off in all my other .357/.38 chambered guns. So, first thing that came to my mind is that someone put a lighter mainspring in it. So, a call to S&W and they sent me a new standard power mainspring. Didn't help. So, next thing I thought of was that the hammer nose (firing pin) might not be long enough, or has been peened by a lot of dry fire from previous owners. So, I installed a Power Custom hammer nose. No help. I just ordered a new stirrup, mainspring, and cup for it. I thought maybe the "cup" (not sure if that is the correct technical word) at the bottom that holds it in the frame might be wore enough to cause these problems. I doubt that is going to fix it, but figured it was worth a try. I am stumped. Any ideas?
