    What's the difference between 243 Super Rockchucker and 6mm-06?

    Does anyone have load data?

    The Super RockChucker may be blown out a bit more at the shoulder than the 6mm-06 if memory isnt failing me. For either you should be able to start with 240 Weatherby or 6mm/284 starting loads and work up to a bit above max in either of those.

    Thank you so much. I managed to obtain some case drawings with dimensions from Pacific Tool and Gauge. They make many chambering reamers.
