I had to misfires this season form my Winchester 270.........very old gun and pretty worn out.......I sent the cartridges to Winchester and they told me that my firing pin was too light..........it doesn't misfire every time or even once in a while...just twice this season for some reason........should I get a gunsmith to do this or can I do this myself in your opinion?

Any help out there?
