I'm wondering if someone could kindly share the Nosler data (or point me too it) on this combination, as the Australian reloading manual by Nick Harvey (4th edition) lists a starting load of 68gns W760 with a max of 70gns. I've just checked the Winchester data that lists a starting load at 62gns and max of 66gns - 4gns less!

Having yesterday loaded a handful of fouling rounds at 67gns I'm cautious about using them :?

Cheers,

JD338 - you're a legend. Thanks for the fast response. I have never seen such variation in load data as I've seen for the WSM.
