I just got around to stripping down the new .270 110C that I recently bought used. DOM is 1974 and after cleaning the rifle is slam firing when I close the bolt. It didn't do it proir to cleaning. I just blasted the trigger assemby with gun scrubber, so I did not move any of the screws.

My question is, can someone point me to documentation on how to adjust the trigger and tighten up the trigger. If I close the bolt very easily it won't fire and the trigger is noticibly lighter. Just would like to know how to adjust it or should I take it to a gun smith? I was going to take it to the range tomorrow and fire it, but not now. Thanks for any help!!!
