I was at a pawn shop today and saw a nice looking bolt action carbine. I asked about it and the guy said it was a Beretta in 6.5mm. The rifle looked nice, and is only $119. So my question is, what 6.5mm cartridge does it use??? The action looks way to short to use the 6.5X55 or the .260 Rem(it's also to old to use the .260 Rem). Also how hard is it to find/ how expensive is the ammo it uses?
