I'm seeking load data for the 375 Rem Ultra with the 350 gr Sierra Matchking. Sierra doesn't have any yet and none of the powder suppliers (Alliant, IMR, H, Win) list any. Has anyone worked up a load on this? I have obtained very good accuracy with H4831 and IMR7828, but I haven't had opportunity to chronograph them and with the shortage of brass, things have been on hold until I don't have to cry over every worn case.
