M855A1 vs TTM/Spartan level III+ steel armor

[chopinbloc]

Feel free to make your predictions before watching the test. The conditions are: M855A1 fired from a 20" Colt AR-15 A2 vs The Target Man/Spartan Armor systems level III+ Armaply ATC. This is a brand new product that has only been on the market for a couple weeks. To help put it in perspective, this is my earlier test of M193 on the same plate: https://youtu.be/6RGdXv8YMFA

And another channel's test of M855A1 on a different company's level III+ plate:

Actually had less vel than the previous M193 test (which broke 3,300 fps).

Wow! This is a serious kudo for the ammunition engineering arts. The 5.56mm has veered from one extreme to the other trying to compensate for a small bore, and this design may just have captured it all.

There is no way the powers that be will let us have this ammunition.

Nice job!

As I stated in the other thread, bullet composition has a lot to do with armor penetration....

The steel penetrator in M855A1 is about twice as heavy as the M855 penetrator, and the penetrator is more secure in the body.

I would like to see how well it handles about 20 degrees obliquity....

The A1 penetrator is also harder, pointier, and not covered with copper jacket.

How is the M855A1 round performing in ballistic gel when compared to the previous bullets?

It has an extremely short neck.

Even when fired from a short barrel.
