I have recently aquired a Brwning T-Bolt in 22 Rimfire. I understand there is a continuing bug bear with the slightly stiff trigger and also as far as I am aware without drilling and spring stretching there is nothing else to do but screw out the trigger adjustment screw in front of the trigger guard to achieve about 3lb.

My question is, do i simply jsut unscrew the screw to its fullest to achieve the lightest pull possible or is there a certain way i should do it? Will the screw fall out if I loosen it all the way out?
