The thing that jumps out for me is that the study reports that cheaper bullets like the Ballistic Tip and Bronze points out performed the more expensive Barnes X and Particians on deer.
It reminds me of what Jack O'Connor said about hunting deer. I recall him writing that the 7 mm 120 grain bullet was one of the most deadly deer bullets on the market, when fired at high velocity from a 7 mm Mauser. Jack believed that rapid bullet expansion meant greater shock and tissue destruction than harder types of bullets that penetrated further. I think Jack concluded that increased penetration often does not pay when you are hunting deer.
One thing caught my eye, which was that .25 caliber significantly seemed to register the lowest yards traveled.
I've taken deer with a .303, 25.06, 30.06 and 300 WM...and by far the 25.06 dropped more game in their tracks DRT, often shockingly so, than any of the others.
Always used Federal Premium 117 Sierra GameKings.
I maintain, if I had only one caliber for hunting deer, I just don't think it gets any better than the 25.06.
FWIW.
Although I have also noticed that many of the animals I shoot with the .25-06 go straight down...
