Re: 300 ultra project
Trigger job, and brake. I would say bedding, but that is going to be difficult on the plastic SPS stock. Buy a good used wood or you can bet a takeoff Sendaro for $150 or so.
For the money, Harrells is great brake ($35 on BR central) and so is the Holland ($65). The Harrells is widely used in the BR community and they are looking for the most reduction. Money is normally not an object on a $3000 gun, but the Harrells is one of the most common due to its high efficiancy,. You can spend more for sure, but will not be able to tell the difference except on the Internet blogs.
