Ray, going on poor memory here but did not AR/Saeed have something (a long while back?) on the order of a .416 Rigby necked down to .375??? IIRC, that was one rompin, stompin buffalo killing machine, up into the hundreds, even. I think he may also have some reloading data for that thing in the "Reloading" section of the AR site but not too sure about that.
If so and even though a wildcat, that would seem to be the best of both worlds for purposes of this discussion.
