RE: .280 Caliber
I second akbound, the 280 is not better, no worse than the 06 or 270. Same casing different bullet caliber. I look at it this way, it did not really take off when introduced so either folks didn't like it or more likely it didn't offer any advantages over the existing cartridges. Don't know about your area but in mine it would be hard to walk into any shop and have hopes of a selection of factory ammo on the shelf. If you buy this rifle, learn to handload or stockpile your ammo.
