Yep, I know, the Easy Eight has the long '76' (i,e, 76 mm L/52 M1A1, M1A1C or M1A2 gun) but the point was that versus T-34/85 it was the ammo that mattered....[/quite]
Not really, the T-34/85's protection isn't all that good even by the standards of the time.
A standard Sherman model mounted the 75mm M3 L/40 main gun.

Not after mid 1944 they didn't, and none in Korea except a few dozer and mine flail tanks.
Likewise, the British Sherman Fireflies featured the Royal Ordnance QF 17-pounder gun of 76.2mm which was significantly better than the American M3 main gun (with better penetration value than even the fabled German "88").

Ahh the OQF 17pdr shot twice and hit once! Yup shoot twice hit once, the gun had serious accuracy problems with its best AP round.
Even though the 76mm gun was a much better anti-tank weapon than the 75mm M3 gun it replaced it did not have enough power to penetrate the front of the new heavy German tanks that were seen in the ETO.
Couple of questions for you.
can you find any proof of a Jagdtiger in combat on east Front.
can you tell me what kampfgroup Pieper was and what tanks it had?
These tanks were the Tiger II and the Jagdtiger, and both had frontal armor that was well sloped and too thick for the 76mm gun to penetrate even with the APCR-T M93 projectile.
The jagdtiger never saw combat in the east, and the Tiger II saw combat on both fronts. No gun mounted by any allied vehicle that faced them ever penetrated the front of the Tiger II, jagdtiger or Elephant.
The 76 mm L/52 M1A1 gun performed poor when compared Kwk42 L/70
Yup, but the US like the rest of the world wasn't iterested in a better 75 with no burstign charge but a bigger bore that could do both AP and HE roles equally well. The Kwk 42 would only survive WWII in the form of the CN-75-50 mounted on the AMX-13. The gun it was designed to replaced the Kwk 40 actually outlived it seeing service in some countries into the late 60's.
In Korea, the M4A3(76)W Shermans with their HVSS suspension systems were the primary mount of the US Army at the time. The M4A3E8(76)W "Easy Eight" was similar in fitting the '76mm' main
The North Korean T-34s lost their momentum when faced with U.S. M26 Pershing medium tanks, ground-attack aircraft, and when the U.S. infantry upgraded their antitank weapons to 3.5-inch Super Bazookas hurriedly airlifted from the United States.
