358 STA's are all custom so may vary a little in internal geometry but I have used Rel 22, IMR 4350, Rel 19 and IMR 4831 in this cartridge and all produced velocities meeting or exceeding those same bullet weights from a 340 Weatherby.
The Weatherby had a 26" barrel and the STA a 24" barrel. Recoil and blast was also equal.
Should be a relatively easy task to work up a load.
