Thread: Tips for increasing shooting range?

Just recently got a new rifle:

Remington 700 XCR II (extreme conditions rifle) in .280 <-- what do you guys think of the rifle and the trYnite finish?
leupold 4-12x40 VX-II
and also a Harris swivel bipod

I am currently using Federal ammo. people have recommended i test out every brand available for the .280 calibre so i can find the one my gun 'enjoys' the most. (i dont have access to reloading gear)

Should i change the stock? (currently got the original with the 'grips') if so for what benefits? and what can i do to get this gun shooting longer ranges? (by longer ranges i just mean being able to confidently shoot at ranges of 300-400 metres with faith in my gun to kill.

I know i need some core tools like a range finder etc.

What experiences have you guys had with r700's? (good or bad)

oh and also im new here so hello
