Great Idea! ThanksIf you want something fun, cheep to shoot (& build) that hits steel and beasties hard I'd build a 7.62 x 39. Get your gunsmith to rechamber a salvaged 308" barrel, preferably with a 10 inch twist. A 308 boltface will chamber and extract but may not eject, or open up a 223. Shoot mill surp or handload with good 308 bullets. It's what I did or just get a ready made ruger?
