Small point:
The only reason there is a large range of bullet weights per caliber is that traditionally, the cup and core designs fell to pieces on impact. The idea was to retain bullet weight and increase or maintain penetration, because of this retained weight.
With modern technology, that old theory is as obsolete as the 300 grain factory load.
The modern bullets in the 200-225 grain weight range will outperform the older design 250's in most cases, Parition included and that, was always "the" bullet in .338 caliber.
