Interesting article but simplistic in its approach and scope. Often you need to change powders (go slower) with an AI to really see what a cartridge will do.

The comparrison is very skewed against high velocity cartridges in that he evaluates them on a % velocity gain basis rather than a FPS gain basis (going from 2,000 to 2,200 fps results in a much "better" gain the way he defines it than going from 3,500 to 3,700 fps). This is why the 250 Savage comes off looking very good in the article while the 22-250 (based on the same case and getting roughly the same increase in capacity) comes off as marginal.
