My experience as well with API at 100 and 1" plate. If you want to see a really big hole, use some AP black tip.

I'm willing to bet 1.5" minimum. Maybe even 2 inches. I know it will go through 1/2" AR500 like it doesn't exist at all.

Is all API pretty much the same?

Will depend on the steel. Mild steel vs. Ar500 etc.

I tried 2 inch solid steel elevator weights with api and it did not go thru. I'd say 1 3/4 would be max at 100 yds

This was shot at 100 yds. It also knocked off about an inch of concrete of the target stand behind it.

I've shot 1 1/4" thick at 100 and it was no problem for it. I always wandered what the limit was. Cool thread.

Nammo lists their new production as follows:
API(Steel core): 22mm(321-375HB) @ 100m MK211: 12.2mmRHA @ 1000m M2-like Tungsten Core: 22mmRHA @ 900m |

Quoted:
how thick of plate steel will an API round go trough at 100 yards? Today I shot a 1" thick plate steel at about 100 yards and it went trough it like butter. I had the plate angled a little away from me so the bullet path was at like a 45 degree angle. I was kind of impressed. Years back, a video made the rounds that was made by the marines. They fired API at various things, steel plate, steel tractor weights, manhole covers, a safe, etc.. IIRC, it blew right through the 2" plate like it was nothing. |

I have a 1" plate that APIT goes right through.
The cool thing is that ball with a steel core will stick halfway through, with the sharp point sticking out the back. |

We had some penetrate at around 800 but some that did not at closer ranges. At 1,800 it will still plow right through softer metals |

Bit of a similar question.
How deep/thick does a dirt berm need to be to stop API? Say at 100 yards? |

You can look it up, if I remember correctly it should be at least 24" if not 36". That would be packed not just piled up dirt.
The same tables will show you how many rounds it will take to punch through concrete and other barriers. |

I took those numbers directly from their own pdf found below: Nammo Ammo PDF 2014 |

Just keep in the back of the mind - when AP goes through a metal plate, bullet becomes very very VERY HOT. Bullet then lands in grass or bush on your improvised range and you will likely have a FIRE on your hand.
Have seen a guy with a Lahti do just that, shoot AP round at a metal plate, which set a big hill on fire. It was windy, so we did not stop the fire until it got to the top of the hill. Its amazing how quickly fire spreads when its windy!!!! Needless to say, the farmer to whom the land belonged did not hold another shoot.. So be careful out there, especially in summer, unless you want to see your name in the newspapers and on TV. |

Pic of fmj and api core. Notice the api hardened core is more pointy than the mild steel.
Powder in a api pill 
Bowling ball hit with api. 
I also have a chunk of 1.5" steel like above with a api, fmj, 308, &556 hit on it. Pretty cool |

API will go through 3/8 AR500 at 500 yards.

M82A1 shot at 1000 yards. The 4" pole is hardened steel. There's a nice 1/2" hole in the front of the pipe.
Not sure why the link is showing instead of the picture... |

A fellow shooter made the target stand and it was some discards he got when he worked at United Defense.

My dad worked at a place that built sub doors / hatches? and brought some very wierd pieces home. One piece was about 1/4" thick, we shot it with a 30-06 at about 50 yards and it stretched a huge amount, like 3" or more, and never tore. It wasnt hardened but softened i guess.? It was before cell phones and such so no pics but i have yet to see any other carbon steel stretch when hit like that stuff. Hopefully its not some classified tech still  . If u guys never see me post again u know why. LoL
