    Buck E,

    The .243 Super Rockchucker is made by necking down 30-06 cases or some derivative such as 25-06 which would save some time and effort. Dies are available from RCBS and those companies that carry them. It will be similar to the .240 Weatherby in case capacity and performance but without the belt.

    I suggest that you make your cases to match the chamber you have and then measure the case capacity and then work out your loads. As a wildcat, these chambers can vary enough that you will want to know exactly how much the case holds.

    Best.
