Drilling through hardox

Went out with some 6mm hardox this afternoon I took some guns with me to try out.. 22lr nice ping off it and good splatter 17hmr the same I was able to get some node groups on it. Next some birdshot not so much of a ping. Then comes the buck shot definitely some more power with that. Now finally the 222 rem. First shot with a 50 grain sp next 2 with a 50 grain v max. Went down to look at the target only to find a lovely nice hole clean through the hardox.... I was not expecting that! Must have been the soft point the v max just dented the steel. Next time 10mm it is.

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?
 
Are you absolutely sure that's Hardox ? My gongs have taken hundreds of hits from 308, 6.5 etc without much more than a splash mark and no real indentation. They are 10mm, but I can't imagine a 222 softpoint would put a clean hole through even 6mm Hardox ?
 
Not a chance. I have some targets which have been hit many many times with 300 win-mag down through 30-06, .308, 6.5x55 to .223 and they just show splatter.

That will be en8 not hardox... you have to heat hardox in the exact spot with a cutting torch then it can be drilled

Hardox isn't AR plate ! Big difference, its good but nothing like as good as AR 500 armour plate. A lot easier to obtain though as its used in digger buckets etc for good wear resistance

That in the vid is hardox 400 used on cultivator legs, when others come in they cut out the warn front edge and weld a h400 shin on the front...
i will get a piece of their 16 mm and shoot it with the .270

If you get thick enough std mild steel will just crater some until its taken so much its work hardened and has fractures all over . Meanwhile there's a reason AR is more expensive and harder to get in smal, quantities
 


high speed soft points at close ranges are the worst for damaging gongs but a 222 shouldn't have managed it. The usual common contenders are 22-250's, 220 swifts and 58's out of 243's below 200 metres. The Caldwell ar500 gong in this video does give some general comparative values

Having spent since 16 (60 next month) as a toolmaker, I have machined all sorts of steels. The most useful is
EN24T it makes for a tough piece untreated but heat treat & temper then you have a beast of a part.

Short vid of copying a cutting blade as the ordinal's were too brittle and snapped.
Hand heat treated to cherry red dipped in oil and tempered to a blue edge.

En24 T wel, yeah but pretty spendy and I have only seen it in bar not plate , though its probably available at a cost and minimum size I guess

The T actually means its been heat treated does it not ? I don't buy much EN stock but pretty sure it does

En is emergency number from ww2 and it stuck ever since. those blanks are from 6" bar stock then blocked up.
T i think stands for tough but also heat treatable....
cost only gets passed on lol

En 19 comes in std and T the T means its Treated as in heat treated. EN 19 is what most hammers are made from its bought in for thier protection in std form because any forging would screw the ht up
99% sure if you buy T then HT your doing more work and probably growing grain but like I say its not something I use much at all
EN 19 , 24 etc up are all heat treatable as through hardness I think its EN 6 up are case hardenable only ?

The original 'EN' or 'Emergency Number' material designation was developed during the years of WW2 to aid the standardisation of steel reference specification and production of components produced from materials. The EN reference has continued to be used from that time - many attempts over the years have been made to update and circulate a new standard, but the original EN designation tends to remain in the workplace. The second most common material designation used in the UK is probably the BS970 standard - although officially this has been superseded by another european standard, confusingly also named the 'BS EN' number. The BS970 standard however was designed to clearly detail the carbon content and the specific type of steel via the numbers and letter given to the material (as shown below)
 
AR500 is not armour plate - it is an abrasion resistant plate similar to other brands such as Hardox with a hardness that centres around 500HB . However there is an 'AR500 armour' brand of products out there just to add confusion.

There are in fact a spectrum of armour plate types and standards.
