    10mm 175gr LEE load question

    can I use 165gr jaxeted data for these?
    I ask because I'm wondering how much less pressure cast boolits produce vs jacketed counterparts.
    my mold has the bevel base removed and they weigh 173.5grs when sized and lubed

    You'd be better off using 180 grain jacketed data.

    is this based on experience?

    The 180 gr data will be a slightly smaller powder charge than one for a 165. So I'd say it's a safety thing. Better to work your way up.

    yes, but wouldn't a lead bullet produce significantly less pressure than a jacketed counterpart?

    it just seems to me like a lead bullet would create pressure more similar to a jacketed bullet that weighed 8grs less, rather than one that weighs 7grs more
