RE: 7mm Ultra Mag vs. the 300 Ultra Mag
Stone, theres more than one way to skin a whitetail, consider this, I use this setup for powerline and open field hunting. Get an accurate rifle, something like a remington 700, chamber it for a non magnum cartridge that is easy to shoot, 280, 3006, something that wont make your fillings drop out of your teeth when you shoot it, mount a premier reticles leupold on it, and buy a Leica range finder. Ultra high velocity isnt the only way to make good hits at long ranges. The premier reticles scope is regulated for one particular load, so there is that drawback, but for me its much easier than trying to shoot a heavy magnum accurately. Something to consider.
