I put a Jewell on my Rem. 700 PSS -- The one w/ the safety. Had it installed by a Rem. approved gunsmith. (I have $3 K into the rifle and scope, let's not mess up the warranty.)
Adjusts down to 1.5 oz. pull, and ZERO movement. Jewell says if I want to go below 1.5 oz. they will supply the spring for me at no cost. I have it set at about 4 oz -- which is spectacular on a bench!
Best $$$ I ever spent on a bench gun! Now I get to concentrate on wind, drift, bullet drop, rather than working on trigger pull.
Timney triggers are in the same league. Money well spent!
