I have decided on a 300. win mag and will get it throated for 210 bergers. I want this rifle to be on the lighter side without sacrificing accuracy. This rifle will be dragged along on long hikes, mountains and valleys. It will also be used for sit down rifle. This will be my first build and would like as much help as possible. I have a remington action i will get fully blue printed, holland recoil lug, I believe i have decided on a Brux barrel (i need help with the length. 26" or 28". Remember rifle on the light side), 3 port muscle brake, McMillan A-5 or McMillan A3 (A3 is lighter and im leaning that way right now), Pillar bedded and fluted bolt and jewel trigger. Am i missing any important? this is my first build remember. What barrel length. i want to keep it as light as possible so i was leaning towards the 26 but someone said the 28 is better for the 300 win mag. I am looking into a #4 or #5 contour barrel. McMillan A3 is lighter so im going that direction unless someone says the A5 is better?
