Back to the Hodgdon site:

300 Win 150 grain 72 grains of H4350 gives 3200 @ 52,500 cup

308 Nor 150 grain 73 grains of H4350 gives 3190 @ 51,200 cup

Same bullet, same powder, same units, same velocity but significant more pressure in the 300 Win.

See, I still don't get it, other than I'm pickin' schidt with the chickens. smile
