450 & 223 vs 1/2" plate

[tbirdman74]

Here's some pics of the difference 450 vs 223 vs 1/2" hot roll plate at 115 yds.

Circles in black marker are the 450, notice that a couple still have orange paint at center of bullet strike. Was surprised that they didn't do more damage.
450 factory rounds, 223 were 55 gr HP tula brand.

Looks like a fun shoot either way. If the target had been something you wanted to kill the 450 would have done a whole lot more damage to flesh and bone than the 223. Notice that the holes from the 223 show melting of the plate. That has to do with a phenomenon that occurs when high velocity projectiles hit metal. Don't remember the term (help me here Wildcatter) but it is the principle that high speed anti-tank rounds use. The 450 impacts on the other hand just did brute force damage with little melting of the plate.

Brute force is an understatement, the whomp it made when it hit was impressive.

Are you referring to Vaporific effect?

Thanks for once again causing me to lose myself in those mesmerizing, understanding furthering, imagination capturing, motion pictures of Werner Mehl, that are ripe with physics lessons. I have a hard time looking away. My favorite observed effect is the tiny shards of ejecta that form and launch from the edge of the plates, as the bullets pass through and generate a shock wave that propagate out to the edge of the medium. They start around 00:27. It's too cool!

I think WC is working on an AR platform for that round...

Knowing him he's been there done that and it's sitting in the closet collecting dust.
