Barrel profile is sporter, not sure on length (I will check tonight and edit this post). I bought it from the original owner and he claimed less than 100 rounds fired, said he killed 1-2 deer a year here in Virginia and fired a few rounds to confirm zero before the season every year. I believe him as the rifle looks like it has seen very little use.
I haven't shot it, I mostly archery hunt and bought it on a whim back in February because I have always been intrigued by the 280. I figured I'd put it out there for sale/trade because I got a wild hair for a 10 gauge to shoot geese and haven't developed any attachment to this.
