And that flatter ball is less likely to exit, due to the increased resistance once it flattens...
I've heard this discussion since the '70s...Never has been resolved...
LOL...I've resolved it for myself...I don't need 2 holes for a big blood trail when the deer is down in plain sight of me
Yes but I thought that you experimented with the shoulder shot, and found that it disrupted the spine, and with a .40 that went deep enough, or with larger calibers, either way with that shot = DRT? :grin:
I don't go for two holes = bigger blood trail. I go for two destroyed lungs, and the deer fall over in a very short distance... as you mentioned, no need to worry about a blood trail. :wink:
But..., after reading about your results, I am thinking of using your point-of-aim on the deer in the future. It makes sense in your explanation of why it works, AND your empirical testing results look pretty good too. :bow:

While impact energy causes round ball deformation, it alone is not the single factor in determining bullet performance. Higher impact energy will result in greater round ball deformation, but when all other factors remain equal, the deformation of the larger load might not equal a large enough increase to give you significantly greater deformation, or results.
For example my load of a .530 round ball with 70 grains of powder is only 66 ft lbs. weaker at 100 yards than the same bullet launched with 90 grains of powder. That equals a 16% difference in energy with the higher load.
So if the deformation was of the same proportion, then a .530 round ball that deformed to .570 with my pet load would deform a mere 9 hundredths of an inch to .66, with the larger load, while not increasing its mass.
All other factors being equal, I doubt the difference in effect on the deer (if any) would be noticed by the hunter.
