I was able to get the x-mark pro on my 700 down to 3 lbs, and it passed all the safety tests.
Thought I'd post my experience, as info for this trigger seem hard to come by on the internet.
Visigoth is exactly right about all the screws being coated, and only one of them (the one he specifies above) being adjustable by the "common man". The coating "melts" after 30 seconds of exposure to Nail Polish remover. I was able to adjust my trigger down to nearly 32 ozs before closing the bolt fired the trigger....so now it's set at 2 3/4 lb, for some safety margin. The screw got a blob of Blue Loctite, and after that set, the whole trigger assembly got a shot of Hornady One Shot dry lube.
Tuck2 has a similar post on the following thread at shootersforum...

I would emphasize performing several function checks on the trigger (closing bolt briskly, safety on/off, etc) prior to calling your adjustment complete.
Hard to feel the difference between the Timney I have on a Mark V and this trigger...feels great so far now!
