i have a new rem. 700 sps with the x-mark pro trigger in it. It was to have a 3 1/2 lb trigger pull from the factory, but was 4 lb 10 oz. i only dry fired it 5-6 times then backed off the screw in the trigger like the ins. said to do , to lighten the pull. i did 1/3 turn with no difference. then another 1/3 turn and had 4 lb but had twice the bolt relieced the firing pin as i closed the bolt. like it does if you hold the trigger and close the bolt, not close bolt and click. i backed off another 1/3 turn and had 3lb 10 oz to 4 lb 4 oz. it moved back and forth. 1-2 more times of piring pin droping. i tighten it back 2/3 turn and have 4lb 6 oz +- . the firing pin still droped again. i shot 4 rds to get the scope sighted in at a 100yrds. i would put the safety on to chamber a round then set it to fire. when i opened the bolt i would put he safety back on. this way i was safe. i cleaned the barrel and today i shot 4 more rds. i am doing this to break in the barrel. i also have dry fired it 10-15 times with out any problums. what is up with this thing. i ordered a spring for the ft. screw that is spose to lighten the pull. or i could get a timmy trigger. the gun is for hunting and 4 lbs is fine for that. i will shoot most of the rds at paper . any help ??
