Drilling through hardox

[spannulman]

This is all interesting to someone who has no technical knowledge around steel. And I will endeavour not to smile when I next watch a film with a close range shoot-out using AR15 etc and people take cover behind the car door.all that will do is introduce plastic and foam to your wounds, in addition to the FMJ rounds of course.

i was shocked the first time I fired the 243 at a mild steel target at 100m, or saw them go right through an 8-10” log at 500yds. Nb I had a bag of flour placed atop the log so I could see it over cover. And the first few rounds to get the holdover splintered the back side of the log.

This is around a 2” thick aluminium plate we have had a go at zeroing on. The craters are 70g Sako varmint from around 300yds and the splash in the middle is a 100g sako gamehead from 400 yds.

Not sure, it was a friend's gong. But something hard because we've shot it hundreds of times with his .308, my 6.5x55 etc and they barely leave a mark. I suspect it was over hardened because the hole was very different to the crater you'd get in mild steel. It looked like it had fractured. I can get a photo if you like?

Edit 2 - I was quite pleased with the shot placement too seeing as the evidence is set in it forever!

This is my gong Neil cause the hole to fracture
I punched it out with a 308
I do believe it to be hardox500 or equivalent
The splash’s are from 308 6.5 and 243 I believe m
The 223 doesn’t hardly register on there
The gray circles may be 22lr exploding on them

I once had words with a guy (he said he had been shooting rifles from when Adam was a lad ) using a 1/4 plate , well rotted tree ring slice and a dry stone wall as his backstop for a 243 ! My neighbour was the other side of said wall mowing off the rushes at the time ! He told me his son was the ex editor of a well known shooting magazine ( not sure what that qualities anyone one as other than a none dyslexic)?

My oldest gong from BH Targets.
Has received rounds from 22LR, 17 Rem, 223 Rem, 6BR, 6.5x55, 308w, 30-06 and 9.3x62.
Hung at 100m. Dont think it's doing too bad. 5 yrs old. As others have commented I think it's the smaller calibre high velocity rounds that do more "damage".

Quite artistic. Looks
Like the moon through binos.

Take your gong to a shoreditch gallery wearing something artisanal, overalls maybe with a full beard and bow tie, and tell them it is a statement on the spirit of the nation post-brexit/covid and the BLM movement. It might sell for a small fortune.

I've a 10mm Hardox 500 plate from Tom's Targets. . 222 and 50gr sp @ 30yards will only slightly pock mark it

I had a piece of 450 hardox cut and drilled from a tipper body maker foreman said you wont shoot through that 100yds 60gr varmint bullet from my 22-250 splattered next shots holes looked like it was drilled neat as you like foreman coulnt believe it so it has to be 500 hardox

Yeah right but remember the dyslexic brain wiring has many advantages as well as the obvious disadvantage . Einstein was almost certainly dyslexic for example

Being one myself, I agree

I was given a couple of steel ROV markers by a colleague a while ago. 12mm mild steel, vs 22-250 softpoint and BT, Interesting to see how the BT created a completely different crater . . . .

Range was around 100 yards.

A 20 grain Vmax at 4500fps puts a decent crater in Hardox, slightly more than a 35 grain Vmax at the same speed.

My target is indeed free swinging it is hanging there with a single piece of wire. It came from and engineering company with hardox 450 on it. I don't think it is mild steel as all the other rounds including the v max just splattered on it it was just the one sp.

Old thread, I know, but had come across it a couple of months go, after taking a punt on a large cutting of hardox 450 plate from Ebay. I had previously tried the .17hmr on it at 100 yards, which made no mark on the surface. Gave it a proper rattle with the .222 and 50gr Federal soft points. Right to left.... 100, 180, 200 yards

Hardox actually comes in different grades of hardness / toughness depending in the users purpose . its starts with AR ( then a number)

And you will find Hardox targets are 450>500 which you won't drill unless you spot face with oxy/acyl
This "shins" on the legs are AR 450 the leg is EN 8

Filmed this morning as it was going lunchtime.

222 will hole 6MM hardox all day long at 50m you need 10mm really at that range

Bring on the toy .222 25mm AR450

There's no "hardox" you can talk about. Hardox, as said is trademark of SSAB and comes in nominal hardness at least from 400 to 700. Along with thickness, you should know the nominal hardness (and what has been done to the steel before final product is ready).

AR is sometimes abbreviation for Abrasion Resistant, i.e. wear steel, that includes Hardox. Other times it might refer to Armox, another steel from SSAB that is more or less armor steel along with Ramor.

Depending on steel the nominal hardness might go well above 1000, and it doesn't have to be armor steel. E.g. vehicle mounted lifts might use this kind of steel for the telescoping beams. If steel with high hardness figures is used as armor, it's usually something else than plain homogenous plate.

What does EN stand for (with out googling it lol)

I shoot at my 10mm hardox target with a .308 150 grain sst bullet and it doesn't even put a dent in it.
It is a target on two chains so does move when hit. Is your target fixed?

It could be Chinese “Hardoxi”
