Every 3 or 4 shots, when I squeeze the trigger to the release point, the trigger goes click, then there is a slight delay, the firing pin goes forward and the cartridge fires. That delay is driving me crazy, it cost me an elk last season because of the delayed reaction of the firing mechanism. Any thoughts about adjustments, should I replace the trigger, if so with what? Sometimes it goes off crisply, like it should. I've cleaned it and it still does it. I took it out yesterday and 3 out of 7 shots had the delayed reaction. Very disconcerting. What do you suggest?
