Those two TSX's you posted look great; like out of a Barnes ad.
I'm surprised they didn't exit, though. Perhaps SD does still have some meaning, even in the world of mono-metal bullets? Perhaps?
SD is as meaningless as "teats on a boar hog" when talking about bullet penetration without taking into consideration bullet construction and shape. Flat point solids of less SD out penetrate higher SD round nose solids consistently. SD is totally irrelevant when comparing expanding bullets. Simply stating SD has no validity without taking into account the other variables that are in play
