I'm a little weirded out by some of those numbers. For instance, how is an '06 case throwing a 300gr bullet at 2500 when my much larger .340 case is maxed out (at least by Hodgdon data) at 2570 with only a 275 grainer? Moreover, the hottest max load for the .375 H&H (again per Hodgdon) is only 145fps faster and that's with a compressed load of 4350.

If there's one thing I've become certain of it's that there's too much certainty in the world.
