I had a smith install a timney trigger on my Remington 700 300 Dakota. Went to shoot it and firing pin is not striking primer hard enough, It will fire every third round. Thought it was a bad batch of primers but have been shooting the same lot of primers out of this rifle with old trigger and shot flawless. I took the firing pin out to see if there was a bunch of gunk slowing it down, it was bone dry. I know I need to take it back to the smith but he is out of town. These triggers are pretty simple stupid to install, I can't imagine getting it wrong. Any advice would be great thanks
