I respectfully suggest that you try to duplicate those same tests using 'premium' bullets. I think you'll find 'different' results.

Thanks for your civility Jerry.:)
You might be right, but the only premium bullets *** back then*** were the old Barnes pure copper & lead & the Nos partition.
"back then" and 'Barnes & N P' tells me it has been a long time SINCE those tests.
I encourage you to RE do the tests w/todays Modern Bullets.
It makes sense to me that c/c bullets expand much more at HI vel and therefore reduces penetration.
We have a few more Premium Bullets today that will withstand HI vel and penetrate MORE.
