we've covered this topic a lot.....perhaps most of it on the old NEF site, but a 'search' for accuracy might help. here's some ideas, too.
make sure the scope, rings and base are all tight. i use loctite on all screws, even removing the base and loc-titing it before shooting a new rifle.
make sure the barrel is Very Clean, and Very Dry. a dirty or wet barrel will cost you accuracy. a bronze brush is one of your best friends....
shoot off a rest that is smooth and with a low-friction surface when at the bench. do not shoot off of leather or suede -- unless you cover it with something smooth like denim. the forearm must smoothly ride on its rest, the same way, every time.
rest the rifle's forearm just ahead of its back end on the denim....for every shot. just ahead of the frame is where the rifle will be sitting on the rest... the recoil pad must be in the crotch of your chest/shoulder junction held reasonably firmly in place. some guys hold the recoil pad against their bicep for some reason.....which is improper. (yes, i have formerly done it, too)
control your breathing....holding your breath half in / half out when you are pulling the trigger.....which incidentally can be a big problem on these NEF's. you've got to get a good trigger pull if you want success with a firearm.
some guys work on the sear and trigger; but i just drop out the trigger group and bend the tang of the hammer spring where it rests on the lower, inner edge of the frame to lighten the pressure on the hammer. don't bend it too much, because a little is sufficient for a Good pull. my longest/best shot was recently laser ranged (we got the range-finder working this Spring) at 185 yds' which had taken a ground hog in the neck with a .223 NEF last year.
i get in my best shooting when i stay away from caffeine and asthma inhalers.....they hop me up too much! :shock:
Ask God's blessings on all your efforts. Proverbs says, somewhere, that the blessing of the Lord exceeds all effort!
i leave it to you to find it because the search through Proverbs will be well-worth your time. :wink:
take care.
