Load data for the Winchester 175gr STHP

[SimonovsDog]

I bought some new primed Winchester brass and 175gr STHP bullets. Before pulling a bullet from some live Win STHP, I wondered if any of you 10mm reloaders can tell me what powder and weight Winchester uses for this load? I weighed a bullet and primed brass, and then a live round, and came up with a 14.5gr difference. I can't find a Winchester load that calls for 14.5gr of any powder. What gives?

Why not just use 180gr. load data. With a 175gr. bullet, the pressure would be lower and the velocity maybe a little faster.
