your prolly gonna lose at least 250 fps from what you will get with a 22" or 24" barrel, i know this first hand from owning a 16" Ruger compact rifle in 308win. accuracy wise the short bbl means nothing, it can shoot as accurately as a longer barrel. if you say you only are looking to shoot short range, go with any 130gr bullet that shoots good in your gun, zero it at 200 yards and you should be just fine. BTW as another poster has mentioned, the muzzle blast will knock your socks off for sure. believe me i know how it is theres really nothing you can do about that.
