I have a dedicated elk rifle that was custom built just for me. It is a wildcat 30-338 on a Mauser FN action with a Karl Gustav 24" pipe. Super accurate and with Limb saver recoil pad and the KDF muzzle break it backs up like a .243. I also have a 280 Remington on the same FN action built with a 19 1/2 inch barrel. Losing just about 60 fps from full length barrel. If I went to the one gun for every thing, I'm pretty well convinced that the 280 with home rolled 150 grain partitions would take anything in North America that my 69 year old eyes can focus on. I've taken whitetail, mule deer, bear, antelope, elk, ground squirrels and a few other things. I know I have been over gunned for some things but never, ever felt under gunned. Any opinions anyone care to share? Agree? Disagree.
