    Re-chambered into 7.62x51 NATO and cut down into a handy carbine in the 1950's. Impulse buy today after work.

    Looks like the FR7 and 8's were used up through the 70's for second line Spanish troops and civil guards.

    The FR-7 was made using the 1893 action which was not designed to handle the pressure of the 7.62x51.
    There is a safety issue here that you should research.

    FYI I think you mean .308--- Fr-7 is perfctly safe with 7.62x51 but .308 can generate a bit more pressure.

    Prediction: Soon Chainfire will post that he has shot .308s in his, with no issues, and that it is perfectly safe, as per a magazine article he will post a link for, and that proof loads ran higher pressures back in the day.

    And then someone will point out that we are talking about a 124 YO action, with steel from the day, which may not be up to the task.

    that's how this conversation ALWAYS goes.

    And yes, I have read, and have a copy, of the article, but i'll part ways with this one now, and let Chain have the fun of posting it.

    I recently bought an 1893 Spanish mauser made in Spain (Oviedo). I fired it twice and quit, because extraction was hard and the primers were set back. I later found that it would close on a no go headspace gauge without any resistance. Further research revieled that Spanish metallurgy was inferior to other nations. Their receivers are soft and eventually pound out creating headspace problems. So why would anyone want to rechamber them for .308?

    NATO standard, 7.62 X 51, that's why. Also, using what you have, hence the rechambering in the 1950s.

    As to the headspace isue, that also may have been a mismatch bolt.
