You know, in college as President of the History Honor Society, Phi Alpha Theta I literally gave a seminar titled...

"Relative muzzle velocities of World War 2 tank cannons"

Hey! I was president of my college chapter of phi alpha theta too!

Holy Carp!  Really?

Chi Psi Chapter.  Represent!

A somewhat related 1979 report on stopping power of various small arms ammunition from the US Army Ballistics Research Lab (BRL) at Aberdeen Proving Grounds. Interesting "law enforcement" perspective on this report.

The meat of the conclusions are on page 58

FYI, for a real deep dive, there are two other reports in this series. They are at:

Interesting 2018 US Govt. study of the 76mm gun vs. German armor in WW2.  Plenty of math, but also charts where they give you the answers...:)

If you don't want to go through the discussion, go to the chart on page 22.  Big difference between the 75mm and 76mm.

https://archive.org/details/DTIC_AD1045347

Why the large difference?  Was it the gun or the ammo used in the guns?

I think it had to with velocity. The 76mm had a higher velocity which increased its armor penetrating capability. The 75mm could penetrate 4 to 4.5 inches of armor while the higher velocity of the 76mm permitted penetration of up to 7 inches, important when facing panthers and tigers later in the war.

I'm reading Spearhead right now, so your timing is impeccable.

Found this very detailed US Army Medical Services study of ballistics and wounds in WWII.

somewhat macabre
