I have allocated $1500 to put towards a new rifle to shoot 1,000-1500 yards, only problem is I want a .300 win mag and I normally shoot .308 long range. I need help deciding which rifle i should buy or build. I hand load my cartridges and will be hand loading for this rifle as well. I was thinking of purchasing a Ruger Precision with plans of upgrading the barrel down the line. I was also thinking of building a custom bolt action but i do not know which action is best for my price range And caliber. Any knowledge will be greatly appreciated.
