Can't find 338 Federal load data for Berger 250 grain Hybrid OTM Tactical bullets

Anybody know where I can find 338 Federal load data for Berger 250 grain Hybrid OTM Tactical bullets? Can’t seem to find anything. Thanks in advance.

It is most likely because the 338 Federal lack sufficient case capacity to propel 250 gr bullets at an useful velocity, and also because it would force a short action cartridge to require a long action rifle.
