I just had my .338 edge built on a stiller predator action, RC barrel, timney trigger, and hs stock. The problem I am having is I get about 5-6 round per 20-30 rounds fired that do not fire. There is a strike mark on the primer, just not enough to set it off. Even if I try to fire one 2 more times, it still doesnt fire. I have ruled out the brass since I reloaded some of the ones that didn't fire the first time and some of them fired the second time. Just brought it into the gunsmith and the headspace is fine. We also tried out a different firing pin spring just incase it was bad for some reason and it didn't make any difference. Has anyone had the same problem at all? The smith said it could be the trigger sear not getting all the way out of the way or possibly bolt timing. He is going thru the rifle but I hope Im not the only one who has had this problem...
