Do not forget to put something on the screw after you adjust it! They can, and will back out, so fingernail polish or loctite over the screw after you have made your final adjustment. Also, you will have to remove the protective sealant over the screws to get to them, this will avoid the Remington warranty, or they might just work on the rifle if need be and bill you for a new trigger. Try Google or another search engine for adjusting a Remington trigger, the old trigger and the X Mark adjust the same.
More than 1/4 turn by the way. Do it with the barreled action out and constantly check your progress. Be safe and make sure that your firing pin won't go home when you bump your rifle/take it off of safe.
I've done old Remmy triggers and the new X Mark, they aren't hard, but it does demand a bit of respect. About 2-1/2lbs is pretty easily obtained with good reliability. Mine are right at 2lbs.
Good luck.
