    Anyone ever slug thier barrel?
    I've read that early 30's had .308 bores.
    I find this odd and not plausible as the OD of a
    7.62 X 39 bullet is .312.
    The OD of a .30 cal bullet .308
    Why would they constrict the round this way?

    I'm not an expert but I remember when the Mini-30 came out. It was advertised as a .308 at first but it wouldn't hold up to the .308 round and was never shipped as such. In a smart move (IMO) Bill had them converted to the lower power 7.62x39 round.

    A couple more memories emerged through the fog during the night..

    1) The Mini-30 was originally named the "XGI" before the caliber switch.
    2) You can load .308 bullets for the Mini-30, if you want. (Don't take my word for that. Do your own research. My memory isn't what it use to be.)

    Can tell us where you got that information? The action for a 7.62x51 is longer and more massive I would think than the 7.62x39. The understanding in the firearms community was that the mini-14 became the mini-30. I do not a have mini-30 to a make a comparison to the mini-14 action. But normally what works for the .223 will work for AK rounds. The AR15 action will easily handle the 7.62x39 and the AKM (AK47) action will readily handle the 5.56 natio with minimal modification of the bolt face and maybe a few other things. Neither of these w/o extensive redesign will handle the .308. . What I read about the failed XGI project was the question of accuracy that they were not getting. But I am not a historian of Ruger rifles and make no strong claims.

    A friend of mine back in the day, a mechanical engineer, and a couple of his friends pre-ordered the XGI. After waiting patiently for some time, He called the Ruger plant at lunch one day and just asked the guy who answered the phone about it. The guy who answered the phone knew a lot about it and talked to my friend at great length about the problems they were having. My friend thanked the guy for being so informative and honest about their problems and asked the guy's name. It seems that Bill, himself, had happened to walk through the office that day during lunch when most everyone was gone to lunch, and had answered the phone.

    As I said, I'm no expert on the Mini-30 but I'll never forget that story. I know it to be true but I know you don't know me so, take it for what it's worth.

    I bought a blued rifle as soon as they hit the LGS and traded it in for a stainless version as soon as it was released. Still have it.

    Flipflop as found an ad for the XGI. Very cool. http://www.rugertalk.com/forum/f13/xgi-308-a-700/
