    Default 6mm-06 specs

    Does anyone have 6mm-06 case dimensions? I would like to compare to 243 super rock chucker dimensions.

    Default Deeply appreciated

    I first called Douglas Barrels and they referred me to Pacific Tool & Gauge since they provide almost all chambering reamers. I spoke with David Kiff there and he was able to email me a schematic of the 6mm-06 case with dimensions so that I could compare it with my 243 super rockchucker, for which I am looking for load data. The old P.O. Ackley data is way too hot. I did obtain some 6mm-06 load data from Graymist's website for the 6mm-06. I can use that as a starting point for the 243 super rockchucker.

    Again many thanks!!!!!!!!!!
