    what diameter does it throw with your alloy?

    RCBS 7.62-130-SPL. what do you get for as cast diameter? casting temp? alloy composition? ladle pour? bottom pour?

    thanks,
    Brian

    Brian, no offense, but you'll be very lucky to get the same diameter from another mould and alloy as someone else does. RCBS usually makes a very nice mould and they often drop +.002 above stated diameter with WW alloy, but the individual moulds vary a lot, same with our alloys,

    You'll get slightly different diameters with the same mold, same alloy and different temperatures...Ray

    The Lyman Cast Bullet Handbook has a chart about different alloys casting diameterer for various calibers (a .44 cal bullet cast of Lyman #2 will be .4XX" while if cast of 20-1 the same mold will cast .4XX"). Books can be pretty handy...
