man, next time you will want the plates at a steep angle pointing down. But ideally if you want to see the performance at that distance (there are legit reasons) you can make ballistic gel block to capture the impact and deconstruction a bit safer.

hope you are well.

We are all well. We are going to complete the test. No angled plates. Going to shoot them square like before. Only this time I think we will use a lead sled as a remote firing position.

Good idea, do it like myth busters do.

It's always a good idea to not angle the static plates, good luck with your test

Im waiting on the AR500 results. My swinging 550 gong dimpled at 75 yds with a 40 grain vmax out of a 24" .223

Use thicker plywood since we all know wood stops bullets very well.

I don't recall ever seeing a static plate that wasn't angled down.

***ETA*** from multiple different target companies:
"It also means that the target face needs to be flat and smooth and that the angle needs to be downward to direct fragments away from the shooter."

"Our 3/8" Angled AR500 Steel Static Targets are laser cut from high quality domestic plate. Angled steel targets can help direct splatter and bullet fragments downward and reduces energy subjected to target."

"AS with all of our Target platforms the Full Hostage has a natural 15 degrgee forward angle to direct richochets donward into the ground"

I knew someone was going to take you serious.

That bullet is way too fast for armor steel, that close. 3200 fps MV is rule of thumb. High energy does not hurt them, high speed does.

When I've had clients want to get DOPE on .224" cartridges, I put clays on the berm at 200 yards, otherwise it'll dimple my AR 500.

Pretty sure this about sums it up thus far. We had complete penetraton on the 1/4" at a mv of 3150, but nothing really but a very light mark with the 77g smk at 2990fps.

This was part of the reason of the test.

There are several parts that intend to test other than that though.

Also, to answer another poster. There is some mathematical formula that gives a percentage of energy lost per degree of angle. I don't want to leave anything to guessing which is why I am shooting it square.

The jacket separation was due to full penetraton of the 3/8" mild steel and the thicker jacket construction of the target style bullet. It basically peeled the jacket from.the core, flipped it inside and created a lightweight, high velocity projectile in reverse.

Had that jacket been another inch to the right, it would have gone right back down the bore.

I also have no doubt that if that jacket would have struck the 3/4" plywood it would have stopped it.

Regardless, the testing will be completed, albeit with largely different testing protocols in place so we don't repeat the previous.

Ultimately, besides everyone seeing the fallacy of it, in the end I believe there will be some questions answered as far as external ballistics vs steel of a given composition.

I have some hay baling twine that I can send you, should be good for several thousand trigger tugs. Hate to think I could contribute to science and did nothing.

Lol. Thanks. I think I've got the trigger pulling contraption figured out though.

Yup. A little safety protocol goes a long way.

Before you two start testing again, will you both sign life insurance policies where I am the beneficiary?
