It's not new, it's from the same document, they make same thing with 150mm plate for bd26 and later rounds, so for not inclined plates there will be much smaller numbers of penetration(test were done only on plates inclined up to 71-75 degrees) and if take to account that 427mm for L23A1 it's path of round inside inclined target but not it's penetration...

That's very weird. You can't determine penetration depth by simulating semi-infinite plate by just increasing the angle. The data you get from testing the same plate at different angles will be different for the same impact velocity.

China does the same. They have one target plate (220 mm) for their 105 mm, 120 mm and 125 mm APFSDS rounds - they just change the slope for different rounds.

This clears up some of the mystery of why the data for L23 seems to vary so much. Thanks for that.
