A friend and I went out this past weekend to do some plinking and sight in our EOtech's we just purchased from C&S in Sac. ( free plug )

My friend brought along some mild steel plates aprox. 1/4" thick to use as targets. What I thought was odd is the 5.56 green Tips ( steel core ) were not going through the plates. What was more interesting is both the 5.56 & the .223 FMJ were making the same size craters in the steel. The craters were a minimum of 3/4+ deep in the plates.

I also tried 20 rnds of .308 black tip with 1 of 20 actually making it through. I would estimate the distance was aprox 50-60 yards away.

Just thought I would share.

Based on what you have told me, that 1/4" plate MUST have been harder than so-called "mild steel" or it was thicker than 1/4." In my experience, 308 and steel core 223 punch through 1/4" mild steel. Was this thicker than 1/4"? You sure it was "mild steel?" Even if you had this steel hanging from a cable and allowed to swing, my experience is that 308 would go right through it.

Mild steel can't hold up. Hardened steel can, though. I've had that same experience with .308.

I have shot 1/4" mild plate with lead core 308 at 100yds and it divots the HECK out of it... 308 AP goes through it like a hot knife through butter.

This is why it is all legal ammo and not "Armor Piercing"

MILD STEEL.....ya right....5.56 and 308...go right through at 50-60 yds...

More like you had armour plate and wanted to see if it would punch through...not so, much....

I'd expect 55 or 62 grain ball to perforate 1/4 inch thick mild steel. Many many years ago, shooting 3/4 inch thick steel plate at a 30 incline from vertical (unhardened, probably) with M193 ball out of a Mini 14 produced 1/2 inch deep x approx 5/16 inch diameter cratering at 100 yds.
SKS with Chinese mil surplus ammo- when it was legal to buy and shoot Chinese mil spec ball- it would slap that plate pretty hard, digging a broad, shallow divot, throwing a shower of sparks at dusk, meanwhile the steel core screamed through the air, "BWEEEEEE!". Didn't do much of that for safety reasons, but steel core Chinese ball was spectacular. No, fires never resulted.
M2 ball out of a M1903 made rather shallow, broad divots.

...Also how do you get a 3/4"+ crater in 1/4" steel sorry just had to be a smart *****

The friend shooting with me is a welder & fabricator. He said it was mild steel. The thickness was either 1/4" or 3/8" max..since I carried the plate I wouls guess it was 1/4 inch.

The plate was proped up against a tree. I'll take pictures & measurements when I get back home in a couple of days

I think he just meant that it made it 3/4 the way through the plate.

I agree with everyone else here. Just about any 5.56 or 308 round should go 1/4" mild steel plate.

i made some 3/8th thick mild steel plate targets for the lytle creek belt fed shoot and 308 and 6.5 grendel were going through it at 200 yrds sometimes peeling the jacket right off .. holes looked like someone drilled them ..some of the guys at the shoot saw the target after we brought it back in
