Every year or so Remington produces two "off" calibers in the 7600. This year it's the 25-06 and .35, others have been the .260 and 6mm. These rifles are usually hard to get hold of. As for the price if that included scope, you got a great deal. I bought one in the .25-06 this year and paid about $550 for just the gun. Of course Remington produces the old standbys like .270, .30-06, .308 i think, & .280, possibly .243 every year in the 7600.
