There's nothing special about your rifle except for the chambering. Remington's SAUM calibers were very good, but disappeared when compared to volume of sales of Winchester's SA magnums. Many folks think the .300 SAUM was the best of the lot, but you don't seem them much anymore and the brass/components are scarce. I don't think I've seen factory ammo in awhile. That being said, there is a certain following that love the .300 SAUM.
Frankly, for the rifle-only, I'd guess you're looking in the $800-900 range. The scope is nothing earth-shattering but it is good glass.
