I have a few .3006 03A3 Spingfields that I invested a bunch(to much money)into to make a tack driver
the .3006 can get out to 1000 yards but there are many other calibres that wont break the bank.
I have punched paper with that Calibre at ranges over 400 yards and killed Deer at 400yards,
I just don't plan to shoot that far with this calibre.
The .3006 is a great calibre but if you want a rifle that can go that far, go with a .300 mag
all that is, is a .3006 that grew up and got into steroids.
