I don't know about true Weatherby actions, but, given that the Vanguard series is a Howa action, which has a self-adjustable trigger, I believe that it is easier to adjust than the Remington. I have my Remington's taken to a gunsmith for trigger jobs, but a Tikka, Sako, and Howa/Wby Vanguard can be self-adjusted without the need of a gunsmith.
