Offline, in an M4 75 - rockets at 1500 yards I was unable to damage a tiger.
I put over 20 rounds into it, 90% ricocheted after 20 hits at that range, all AP, there was no apparent damage.
I was setup broadside to the tiger. Seemed to matter not at all where I hit it at that range.
Same setup, same m475mm, again broadside to the tiger, again with AP, range less than 100.
With 4 hits it was smoking and with 2 more it was dead.
Instead of getting the ricochet I'd get the bigger hit flash explosion.
But don't take my word for it, test it yourself.
I'm sure your GV skills are better than mine.
Just use a repeatable test where the only change is the range fired from.
Let us know the results.
