So I keep getting confused with some of the info on the ‘info’ pages. For instance, the T-34 STZ (link below)… It says:
- BR-354P: APCR; a composite round with the best penetration but no explosive filler and will only penetrate flat vertical surfaces."
But the chart says the 0% chance of ricochet is up to 66 degrees. Vs the BR-350B that is 48 degrees… Seems to me no ricochet up to 66 degrees is better than 48 degrees, no? So why do they say it will only pen flat surfaces?

EDIT: Fixing my original post for clarity.
Lower is clearly better here, but I agree it’s confusing. The fact that the 100% ricochet chance is at a higher angle of attack than the 0% ricochet chance suggests that the angle would be actually from the perpendicular, not the plane. But that would mean APBC actually has higher ricochet chances than HEAT or APCR, which would make no sense.
I think it’s best read as it’s the angle from the plane, and 100% actually means = 100% chance of NO ricochet, whereas 0% is a 0% chance of NO ricochet… so anything below the 0% figure in degrees from the armor plane bounces off.
So for the T34E STZ (see table), APCR has a 100% chance of avoiding ricochet at angles of 72-90 degrees from the plane, and a decreasing chance of avoiding ricochet below 72 degrees. By the time you get to 66 degrees or less from the plane, it’s gonna bounce (0% chance of not ricocheting)
That’s compared to a regular ballistic cap ammo, which has a 100% chance of avoiding ricochet 71-90 degrees, but can sometimes bite into armor even as low as 48 degrees from the plane.

Weird way to do it… So if it says 48 degrees, you’re good from 48 to 90… and if it says 66, you’re only good from 66 to 90… I always thought it was the other way around.
That cleared it up pretty well, thanks!
Ok… so who does the wiki.warthunder? On this page they say the BR-271K has a little worse ricochet angle (47 degrees) than the BR-271 (48 degrees)… If lower is better, then…
