here I am posting to a thread thats a year and a half old again.
I'd think it best to stick with a NATO round. I'm no fan of 5.56 X 45, and 9mm, though plentiful, won't knock down a deer, so that leaves 7.62 x 51. Of course, I could kick myself thouroughly, in the behind, for not buying the Remington 7600 pump action .25-06 that was for sale on here a while back. If there was ever a versital round it is 25-06. Go look at the terminal ballistics at http://www.handgunsmag.com/ballistic...remington.html ; it has good reach and acceptable stopping power. I say, It will take anything down from hare to bear; though I probabbly would not charge a bear with it on purpose. Plus, you could buy a pistol grip set up for the 7600 remingtons, and the parent case is 30-06. If you had the right reloading tools, that 25-06 pump would be my choice.
