Anyone have data for a 8mm-300 Win Mag wildcat ?

    Was playing around at the reloading bench, and put a 8mm bullet into one of my .300 Win Mag cases, and it got me to wondering if anyone had done it. I cant find any data at the normal places. Im guessing performance would be between the .325 WSM and the 8mm Rem Mag.

    I could not find any data, but www.z-hat.com does have a reamer for that, so it has been done.
    Now my thoughts are that the 300 Win Mag is nearly identical to the 300 WSM ballistically, so the 325 WSM, made from the same case, would be real close to the 8mm-300 Win Mag.
    I've found that if you think of a combo based on another case, someone has already done it. That doesn't keep us from thinking about it though. :)

    8/.300 Win Mag has been done.
    Here is some load data for you
    198gr Bullet
    Large Rifle Primer
    65 gr H4350
    Predicted Velocity 2833 fps
    COAL 3.346
    47436 PSI
    Barrel: 27.5 inches

    You will need Quick Load for wild cat data :):)

    Thanks AFY, I have been looking at Quickload. Seems to be a handy item.
