I use this for reference. All my Ruger M77s have 2.5 lb triggers, with 0 creep, using this method. Click on "drawing", in the 4th paragraph.....and "additional pictures and comments", at the bottom...for more detail.

When finished, I test the integrity of the trigger by slamming the bolt shut with the palm of my hand.....very smartly. None of the triggers will slam fire. I have alot of confidence in them.
