Interesting though, Bob, is the study of Dr. Ed Ashby mentioned in Gregor Woods' book, Rifles for Africa wherein this study first compared the 22 Hornet and the 22-250 shooting a standard for caliber bullet weight in the TSX. Next, was the 3006 and finally, the 375 H&H.
The slower 22 cal gave deeper penetration, the 165 Barnes TSX in the 06 offered better penetration at MV 2400 vs 2700 and the 375 270 TSX offered better penetration at 2400 MV.
One point of note is the bullets were not given hunting ranges but only mentioned "bushveld" distances which in other areas of the book he describes as out to 300 yards.
The conclusion was that better penetration was found at a lower MV since the petals of the Barnes would expand to a 90 degree angle to the shank of the bullet and would act like a scythe rather than rolling back into a more classic mushroom shape and thus having to push rather than slice their way through encountered tissue. He displays a photo of a warthog shot with a 450 gr TSX from his Lott at 2200 or so MV and the thing shows a four-petaled exit wound through the shoulder. Interesting!
