Mike, I have used the .300mag on deer several times and sold the gun because it was too wasteful. Dead is dead, but inedible is waste - plus the gun was unpleasant to carry and very unpleasant to shoot. And a .250 Savage, or .270 Win will both do an excellent job on deer, but don't try to make the .250 a long range gun. I have taken more deer with a .32Win Special (model 94) than any other - but I use it within its range under 100yds. And you are right, "dead is dead" so what does shredding it do for you?
