Does anyone have the procedures, diagram or internet link to adjust these triggers.

Have done Remington and Savage before just not a Browning.

Unless they've changed, the Browning's only have 1 screw and it adjusts the weight of pull. It's on the back side of the trigger under the guard. The last one I worked on wouldn't go below about 4 lbs with the factory spring. The factory trigger was plenty crisp, just stiff. Alot of the crispness no doubt came from the small chromed square that was screwed into the top of the trigger and makes up the engagement surface.

In the end, I installed a Moyers trigger instead which is adjustable for weight of pull, overtravel and has a sear engagement screw. It was about $125 if I remember, but worth it, and the install was very easy.

1st step is to replace the overly heavy springs - brownells sells a kit. 2nd is to adjust the pull weight.
