Free ammo? Hmm... I might have to think about buying a 280. 
thats my case here, dad had this forever in his safe box, now i have it with no way to blast it lol!
He thought is was 270, but it wasnt.
only after pricing out 280 rifles did i find out i would not be able to afford a 280 anytime too soon lol!.
a guy on seattleguns has a 280, he put three shots within a dime at 100 yards with it. wish i could find a project rifle for free hehe!
