Bruce, I have not experienced that problem, but is it not possible that the trigger adjustment screws are fouling when you put the action in the stock ? I don't know why that would increase the load on the trigger though.
I HIGHLY recommend that you follow the correct safety verification procedure as explained here Adjusting the Remington 700 Trigger
I can attest to the fact that I was unable to get an acceptable trigger pull on my own Remington without failing the safety test (slamming the bolt or the butt against the ground would cause it to fire with the safety on), so I finally fitted a Shilen trigger which cost just under $100 and has worked perfectly and is also safe (I didn't need to make any adjustments).
After you are happy with the feel of the trigger it is essential that you perform a safety check as described here. First, slam the bolt closed HARD up to a dozen times watching to see if the sear allows the firing pin to be released. If the firing pin is released, back out the sear engagement screw another 1/4 turn, and repeat slamming the bolt again.
Next, cock the firing pin and put the weapon on "SAFE" and pull the trigger, release the trigger, put the weapon on "FIRE". Repeat this process several times and if the firing pin is released, increase the trigger pull and repeat this process.
Once these safety checks are performed, take nail polish and seal the heads of the screws and allow it to dry. I normally try to use two coats to make sure that the screws are properly glued in place. Once adjusted, the Remington trigger rarely needs additional adjustment and can be as good as many after market triggers.
I have recently purchased a new Remington 700 Classic that quite literally had the God awful worse trigger I have ever felt on any gun. This trigger was rough in the sear engagement and the trigger spring itself was too stiff to allow for any adjustment that was acceptable for my taste. I understand that it is possible to buy replacement trigger springs and to have the sear surface polished but these are tasks that are beyond my level of understanding so I took a trigger out of a well used Remington 700 ADL from the early 1970's and swapped it for my new trigger. I felt guilty selling my old ADL with that new Rem. 700 trigger that was so lousy, but at least the gun that I wanted to keep has a crisp 2-pound trigger that I can trust to work as a quality trigger should!
