Very strange evaluation. This guy uses three different .327 bullet weights to stack the deck in its favor regarding whichever performance parameter he is illustrating. 85 grain for his recoil claims, 100 for velocity/energy, and 125 for penetration.
This has gone on for as long as men have been evaluating guns. Industry (and other) pundits cherry pick particular bullet weights (and even constructions) to best favor whatever point they are trying to make.
Folks just need to understand that there is no "magic" to firearms and ballistics. Bore size, barrel length, and allowable pressures dictate performance. One can fiddle with bullet weights to tweak how that performance is delivered, and bullet constructions to determine what happens when it hits. The .327/.357/.41/.44 mag cartridges all operate at about the same maximum pressures and are all available in the same barrel lengths. Performance increases with caliber in this class of cartridge, as would recoil given equal weight guns.
