Hey guys. I need some help. I have a savage 93r17 in 17hmr. The gun has been great, but developed a misfire recently. It is not an ammo problem. The gun will fire once out of every 2-5 pulls of the trigger. Its getting old. I sent the gun back to the place i bought it. They simply slammed a different bolt in it and sent it back. That didnt fix things, so i took it to a gunsmith. He said that he adjusted the headspacing, but still no fix. I am getting fed up, and worst of all it is now off of warranty. Any ideas on what to do?
