Snap,
I agree that Pearce's loads seem reasonable in general. I've saved many of his handgun articles and he always seems conservative with different pressure categories, depending on exact model of revolver. I haven't used his rifle data, but have used his data for the 45 Colt, 44 Spl, and 44 Mag.
He hasn't gone into detail with the pressure testing but I was just reading his article on primers and their affect on pressure and velocity. So he apparently has access to pressure testing equipment. I know he's a big fan of the 338 Win too, so I'd assume he's done more than a little work with it.
