enigma Posted September 12, 2016 Report Share Posted September 12, 2016 So. folks I have a bit of a dilemma...... A good friend bought some Hardox plate, think it was 5mm thick. It was set up with a nice back stop behind it (thank gawd) but as you can see it didn't hold up to well to a .204 or .223 at 220yards... My question is simple.......how thick has this stuff gotta be to stop the penetration and will it still crater after that. What stuff do the usually use on these gongs as it cant surely be this stuff??? Link to comment Share on other sites More sharing options...
rhhudson Posted September 12, 2016 Report Share Posted September 12, 2016 I wouldn't have thought it shouldn't of gone through at 220yrds. Are you sure it is hardox? I only use mild steel,,, but it is cut from 25mm plate, 300yrds+ it just leaves a light mark, anything less craters but its not shot through,,, yet! normally 10mm hardox should be fine.

tackb Posted September 12, 2016 Report Share Posted September 12, 2016 That's not hardox 10mm of hardox 400/500 won't hardly mark Link to comment Share on other sites More sharing options...
stillair1 Posted September 12, 2016 Report Share Posted September 12, 2016 My gong is 10mm hardox, at 100yds slight marking indent, at 200 it just knock the paint off with 40gn vmax Link to comment Share on other sites More sharing options...
enigma Posted September 12, 2016 Author Report Share Posted September 12, 2016 My gong is 10mm hardox, at 100yds slight marking indent, at 200 it just knock the paint off with 40gn vmax not looking good for the "so called hardox plate" I kinda suspected it might not be what it says on the tin....lol Link to comment Share on other sites More sharing options...
sean223 Posted September 12, 2016 Report Share Posted September 12, 2016 My gong is 10mm 450 hardox and at 100 yards with my 223 and a 75gr Amax it hardly marks it. I'd say That steel is not hardox. Link to comment Share on other sites More sharing options...
Akeld Posted September 12, 2016 Report Share Posted September 12, 2016 10mm hardox and 69gn TMK through a .22-250 at 150 yards makes a slight indentation, think I'd be making a phone call in the morning if that were mine Link to comment Share on other sites More sharing options...
phoenix Posted September 12, 2016 Report Share Posted September 12, 2016 10mm hardox in my 4" and 8" gongs and barely a mark with 243 and 22-250 with MVs around 3800 - I seriously doubt that's hardox in the pics Cheers Bruce Link to comment Share on other sites More sharing options...
MrCetrizine Posted September 12, 2016 Report Share Posted September 12, 2016 I use AR500 plate and 77gn .223 makes a light coppery coloured smudge that wipes off with a finger. They do become work hardened and brittle over time though. My oldest one is 3 years old now and stoked up .223 will crater it a little. Link to comment Share on other sites More sharing options...
Biathlonjimmy Posted September 13, 2016 Report Share Posted September 13, 2016 As above, not Hardox. I have bought 5 gongs over the last few years. 4 are excellent. 1 is full of holes. The problem is I cannot remember the damn fraud I bought the imitation hardox gong from. If I do I'll be sure to let you know. It's just not cricket passing off mild steel as hardox...

bewsh Posted September 22, 2016 Report Share Posted September 22, 2016 BH targets are great no faffing cut to order if you want something different as above, no way thats hardox, even at 5mm they wouldn't peel open holes like that "softox".....

Leadwasp Posted September 23, 2016 Report Share Posted September 23, 2016 Yes my first reaction is that the material isn't a through hardened steel like Hardox or AR. A 500 grade steel is pretty immune to damage at 200 yds+. The most damaging rounds are small, fast and soft. For example our tests have shown that when using expanding ammunition a .223 with ballistics tips doesn't really mark but a .220 swift or 22-250 with soft nose will noticeably mark 10mm plate at 180 yds. At 100 yds the same rounds will almost knock a core out of a 10mm plate. The same grade and thickness of plate is fine for larger calibres certainly up to .338 at 200yds. Simple rule of thumb is don't shoot CF at closer than 200yds unless you are prepared to tolerate some damage. Just one other point the grade of the material is an average and represents a range of hardnesses that will pass QC for that grade. It may be possible to get one batch out of the mill that is a bit softer (or harder) than exactly HBW500. Link to comment Share on other sites More sharing options...

243ai Posted September 23, 2016 Report Share Posted September 23, 2016 My ar500 steel gong 10mm thick.... Link to comment Share on other sites More sharing options...
Leadwasp Posted September 24, 2016 Report Share Posted September 24, 2016 what did you shoot it with and how close? Also, out of interest, how many rounds has this had thrown at it? Looking at the size of the bolts, chain and cut edges (admittedly seen oblique) are you sure that's 10mm? Link to comment Share on other sites More sharing options...
243ai Posted September 24, 2016 Report Share Posted September 24, 2016 It was a 300wby running 165 grain nosler bt what put the holes through it. At 100m+ It would have had less than 500 rounds on it all over 100m. And it's a BH target one I haven't measured it but it looks to be 10mm thick Link to comment Share on other sites More sharing options...
bewsh Posted September 25, 2016 Report Share Posted September 25, 2016 10mm hit with everything from .223, 22-250, 308 and 300wm scuffed the paint off and had a respray ready to go plates with 1/2", 1", 2" and 3" spots 50gr 22-250 soft point and 40 yds!
