Hmm, not a single inert M61 APCBC shot found here, only M61 APCBC/HE. By April 1944 the British were solely using APHE with their 75mm guns, because that’s what they got from the US.
The difference is the British didn’t make anymore APHE rounds after the 3-Pdr and 2-Pdr, they still happily used what was delivered.
