Tank Guns

Draschel: What 90mm gun has 533mm penetration? Or even 457mm. No searches I have seen, indicate a British, USA, Japanese, German 90mm gun with either APDS or HEAT warhead doing that kind of pen hitting 60 degrees The last variants of 90mm HEAT ammunition for guns on Type 61, M48, M56 scorpion had up to 350mm pen. They could also use HVAP ammunition for 370mm pen. There wasn't even any APDS for them.The modernized Cockerill gun still on AFVs today can fire APDS-T ammunition with 310mm penetration, and French O-F3  90mm guns have either HEAT or APDS-T, both 310mm too.  Are you confusing 90mm for 105mm?
