SOMEONE postred here a while back looking for this sort of information. I recently (and totally accidentally) tripped across this data last night, but have ZERO recollection where I originally came across it. All I can say is that it was definitely a page from an old official document, as the data was presented in official old-fashioned typeface and tabular format. I transcribed the data into the format which appears below.
Transcription of U.S.N. armor penetration tests of 16in/45 and 16in/50 projectiles - circa 1920-1921
