The 30-06 is a great short to medium range round but it falls a little under ideal from about 700 yards and on (super sonic to 1200 yards). some of my favorite calibers for pushing past 1000 a little more efficiently, though they tend to be more expensive, are: 6.5 norma, 7mm mag, 300 win mag, and of course my .338 win mag that i have now. Not quite the lapua i wanted but not very far off from one. and as for rifle manufacturers, since machining in almost every factory has progressed to make super accurate rifles, rapidly and more cost effective, almost any brand; remington, marlin, browning, savage, are all gonna be in the same ballpark when it comes to performance and durability. although my personal preference for under $2000 is savage.
