So I've given these targets some abuse, .308, 30.06, 556, 357, .45 etc.. Yesterday @ CJRPC I took a shot with my .308 @ 100yds. The plate could take no more...

 

 

 

time for some 1/2" plates now..

How thick was that plate?

 

I can't believe it went through AR500...all depends on the thickness I guess though.

 

I've shot 30-06 and S&W500 into my AR500 plates and they barely do anything. The S&W500 round did make a couple abrasions but no dents or anything.

these were 3/8"

That had to be steel core bullet because lead wouldn't do that.

in the 2nd pic, you can see what was left of the bullet, i picked it out of the top cap

I have an 8x8", 1/2" thick AR500 brinell plate from Wideners that has taken thousands upon thousands of shots of everything from 22 to 308 with most being 223 and 308 from 100 to 200 yards (and even a few shots at 50) and it doesn't have so much as a scrape on it. Conversely, i have some 3/8" AR500 also from Wideners that i've hit with M193 .223 at 50 yards which put a very slight, almost imperceptable depression but no enough to warrant replacement. I thing the 1/2" stuff is the way to go for full size rifle calibers or anything with enough velocity.

Doesn't look like it flowed like a bullet into mild steel does. It looks like the usual ar500 failure mode of a chunk the size of the bullet fracturing all the way through and popping out. That's how ar500 fails under heavy use, lots of small distortion causes lots of teeny fractures in the crystaline structure until one can just pop it out. The question is was it heavy use? How many rounds before it gave up the ghost?
