I personally do not feel comfortable with doing a trigger job on any rifle except on a Tikka and Sako, which are self adjustable.
As such, have professional gunsmiths do trigger jobs on all my other rifles, like Remington and Winchester. On the Remingtons, the gunsmiths have brought down the pull to 3 pounds even. However, it is not just the trigger pull that they do a good job on. Rather, there is virtually no creep and overtravel.
