Trout,
The weight of pull is a combination of adjustments on the 700 trigger.
Sear contact,and sear spring preload.
Even more imortant is the angle of contact between the sear and striker release surfaces.
On production rifle triggers that are cranked out at a high rate,tolerances are set for a slightly positive angle,to eliminate any chance of a negative angle slipping out.
What often times happens is,that a guy buy's a rifle,is unhappy with the gritty long(Sear contact)pull,finds out it's adjustable and backs off the sear spring preload,then reduces contact for a nice trigger....and gets greedy.
I never adjust a factory 700 trigger below 3 lbs,and .015 sear contact without an angle correction,unless when checked the angle is already neutral(Extremely rare!)and that can be skipped.
The internet is full of places that describe adjusting the 700 trigger in detail,and rely upon numbers of turns on the sear stop screw to determine contact.At best this is a rough method,as the angle is not considered.
For the peace of mind vs cost,having a 'smith adjust the trigger is a good value.
To illustrate the depth of this:
Last fall I had a gent bring me an older 700 that he had bought used at a gun show.The trigger scared the daylights out of him as it was set in the under 1lb range,and he wished to have the rifle bedded and a general going through.
When I got in there,I found the sear return spring had been cut down to 3 coils,and had been packed up from use so that it was sorter than the adj. screw nose.
The sear had only around .005 contact,and had been worn slightly negative in angle.
It was an accident waiting to happen.
If a guy wishes to have a sub 3 Lb trigger that is safe on his 700,and likes the do it yourself approach,I suggest that a Timney,Rifle Basix,Shilen,or Jewel trigger should be purchased.
The units are neutral,and have been made for safe operation at lighter pulls.
Unfortunately Remington took it on the chin from Lawyers,because people did things they were not supposed to do,and violated the golden rules of firearm safety.
Hope this helps.
