I'm probably sure there have been a lot of (Ford vs Chevy) Brand W vs brand C primer discussions on here, put please help with my delema. The last time I went to my supplier he was out of Brand C, so I got Brand W. The went through my progressive reloader nicely and the first bunch , about 100 worked just fine. I went back to the reloading and again all went well, but at the range, I encountered my first 'DUDS'. Bang, Bang Click???. Hand ejected the cartridge and looked it over all is well, there is a dent in the primer. I doesn't seem to be as deep as the fired ones, then Bang, Bang, Bang, Click! OK now I am just upset. The 'DUD' primer looks just like the other one that didn't go off. The fired ones were just fine looking. One opinion is that the Brand W "DUDS" are Metal too hard primers. If so I guess I have to go thru all of them and those that fire are good, and those that don't are too hard???. Any of those I will over haul with my Inertia hammer, and try again with Brand C. Also these were tried in another pistol of the same brand and, same problem. I am ready to hear what you have to say.
