Adjusting Mountain Ascent trigger pull

I bought a Mountain Ascent factory new in 308. Used it on a hog hunt and wished for a lighter pull. I am not a gunsmith and absolutely encourage using a gunsmith if you are not entirely comfortable doing this yourself. I have installed triggers and adjusted them on a number of different action types. Never before on a Kimber, though.

Bottom line - it was a snap. Took 10 minutes.

removed stock and magazine "shroud"
covered rest of action with a rag
did adjustment on bottom screw in front. didn't touch the others
sprayed carb cleaner on the factory Loctite covering the nut and screw
used a wire brush to remove the residue
loosened the nut with a really small crescent wrench
using trigger gauge to test the factory setting - 70 ounces.
turned the allen screw outwards (counterclockwise) one turn
this lowered the pull about 15 ounces
repeated until I'm at about 40 ounces - 2 1/2 lbs seems ideal for me.
holding screw in place, tightened the nut
put a dab of nail polish on screw/nut assembly
reassembled rifle, cocked it, and jarred it repeatedly to make sure the gun wouldn't fire. It didn't, but if it had, I would have started over. Or, gone to a gunsmith.
done - and safety has to be the paramount consideration.

Hope this helps anyone who wants to lighten the factory setting. Love the gun, by the way.
Hope this helps.

Nice input. Thanks for the contribution. Seems most folk here are pistol people, but we love all things "gun" and appreciate additional knowledge.
