Just don't bother hitting it with .338lm AP or .50 API....
I have found the penetration limits of the steel lol.
At 300 meters, tungsten carbide .338 penetrators will cut a hole through 1/2" AR plate like a hot knife through butter. .50 needs to be API, watched some military testing firsthand, and standard AP doesnt fully penetrate past about 150 meters, needs to be API or Raufoss, which work well to at least 900 meters with good effect.
