The only reason it might have worked is higher velocity. The rest of your theory on the shape of a deforming, non AP, bullet is myth, and an easily proven myth by the test, and about a million target, wad cutters, and M855s down range. It’s made up.
The principals of period and area of an impact are correct. It’s just they don’t apply here. The differences are too minute to matter at all
I feel like I’m on ARF or Accurateshooter. Now tell me how your bullets go to sleep.
Believe what you want to believe.
