I also posted this in the hunting rifles forum because that is where the original thread began. However, I figured it also should be in here.
A few days ago, I posted concerning my M77 MkII trigger that was in need of serious overhaul or replacement. Here's the thread link :

I want to thank all who posted, a Timney trigger was a likely candidate. Then John Brennan came along and suggested a simple trigger "job", he sent me the instructions. If I blotched it, then a Timney would certainly have a new home. Well I took on the job and what a piece of cake it was. My trigger started off at 5.7 lbs actually, not as bad as I figured. Well after some filing (and I don't recommend grinding) taking 0.015" off the sear notch. I used a feeler gauge to measure. I then stoned the sear notch surface to a smooth glass finish. Then I changed the trigger face to 90 degrees and put a 45 degree chamfer on the edge and again stoned the newly filed surfaces. Finally, I stoned the mating surfaces of the bolt and the sear. I'd guess about 1/2 hour of work. I now have a crips 2.4 lb trigger -
Thanks Mr. Brennan
