The 7mm Rem Mag actually won at Camp Perry, 1000 yards, a while back. It's perfectly capable. High SD bullets plus high BC's added on to the facts that the original big 7 is fast, flat, easy on the shooter and devastatingly powerful at long distances make it a natural. It's right up there for the one-gun-for-everything title, and even though I use my .300 Win Mag more and more I have a real soft spot for any of the 7's, especially the 7mm Rem Mag. My M658 can startle even the bench rest guys with factory ammo to boot - it puts virtually any premium 160-165 gr ammo whether factory or handbuilt all so close together on paper it's ridiculous and I have no idea why. It's just plain accurate as all hell - should be, it's over 10 lbs with a 3.5-10X44 Zeiss on it.
