yeah, the general performance of rounds is dictated by their reliability to pen and do enough damage, not simply the high amount of pen in the first place. the solid shot that comes default with most tanks does well, with the APHE simply being a guaranteed kill if it pens.
i used to carry like 30 rounds but i figured out 30 rounds = 30 kills. 64 rounds = potentially 64 kills if i get lucky. actually 69 kills cos i could run into 5 spaa/open tops too
Well remember on most maps you can replenish your ammunition on capture points. 64 rounds of ammunition is quite a lot and it causes probably quite a lot of deaths due to ammo detonation.
as some guy who’s played the game a bit, I will tell you anything past 40 rounds of ammo is straight up dangerous to bring.
Also if you want every shot to be a kill, use the stock APHE. It works waay better, post pen is better, and wont take 20 rounds to kill an M18 commander
