Hi All, I'm net to the forum so if this question was previously discussed just point me to the thread. I've had an M77 in .270 for about 6 years. I love it except for the trigger. I was able to polish the sear several years ago and it is smoother now but still too heavy (6.5 Lbs.) Is there a good way to drop this to 3 or 4 Lbs? Or do I have to buy an aftermarket trigger?
