Home Forums Hunting & Shooting Long Range Hunting What Barrel and Muzzle Brake should I Buy

I'm looking to make a 1000 yard tactical rifle. I'm choosing the 338 RUM because I have the action (Remington 700) and its a lot cheaper to shoot than the 338 Laupa. I want the rig to way aprox 11-12 lbs without a scope. I need some recommendations on barrel contour and muzzle brakes. I'm going with McMillan A-3 stock.
