PharmDShooter Posted June 11, 2018 Share Posted June 11, 2018 I’ve searched for a post about This and can’t seem to find it and was wondering if anyone else had experienced it. My AR9 has been leaving craters/dimples in ar500 steel. I’m shooting 124gr plated bullets with 3.6 titegroup. I haven’t had a chance to chrono this ammo but I have shot my steel with no issues. Many insight on what’s going on? Link to comment
rowdyb Posted June 11, 2018 Share Posted June 11, 2018 Can you show a close up picture? Link to comment
OPENB Posted June 11, 2018 Share Posted June 11, 2018 Assuming a 16" barrel, that load shouldn't be any faster than a major open pistol load. Are open guns cratering that steel? I'd be surprised that that load is cratering AR500. Link to comment
Stymie12000 Posted June 11, 2018 Share Posted June 11, 2018 Definitely need to see some pictures. I have seen some slight deformation with minor loads. My open major loads do about the same. The deformation is very minor and does not concern me. The only craters that were a minor concern is from a 22/250 and a 338 lapua at 100 yards. Still very minor craters, probably take a 1000 or so rounds to start really messing it up. But 9mm pcc should not be doing much to quality ar500 steel! Link to comment
CalTeacher Posted June 11, 2018 Share Posted June 11, 2018 Are you sure it’s ar500? We found out the hard way at our club that some of our poppers aren’t ar500. Link to comment
Nathanb Posted June 11, 2018 Share Posted June 11, 2018 I’ve seen 308 on plates less than 100 yards not even scratch steel. I don’t think your plates are true Ar500 Link to comment
Sarge Posted June 11, 2018 Share Posted June 11, 2018 PCC, Open Guns etc should only remove the paint on true AR500. Link to comment
rowdyb Posted June 11, 2018 Share Posted June 11, 2018 The initial skepticism to the claim is valid in my opinion. Link to comment
rowdyb Posted June 11, 2018 Share Posted June 11, 2018 As someone who abuses their own personal steel from MGM and Red Stitch I can say I really doubt that load would leave any discernible, physical mark on a true AR500 plate. Link to comment

Sarge Posted June 11, 2018 Share Posted June 11, 2018 Wow, how many threads did you start on this? lol Hint, one is plenty. PCC and Open guns should only remove the paint from true AR500. Link to comment
PharmDShooter Posted June 11, 2018 Author Share Posted June 11, 2018 Thanks. You guys are confirming what I was thinking. Link to comment

That steel is NOT AR500. Heck--even AR400 shouldn't dimple from pistol or PCC. Where did the steel come from? Link to comment
mwray Posted June 11, 2018 Share Posted June 11, 2018 If a sheet of armament steel reads over 400 on a Rockwell they sell it as AR 500. Very few companies use true 500 rated steel. Most of these cheap back yard target business just cut and sell whatever the steel company sends them Link to comment
Flatland Shooter Posted June 11, 2018 Share Posted June 11, 2018 (edited) I've shot hundreds of PCC rounds that are hotter than your load on my 8" AR 500 steel plates anywhere from 8 yards to 70 yards. This includes jacketed, plated and coated bullets. Also shot them with my open gun (125 gr MG JHP at 172 PF). With a fresh coat of paint, they look brand new. Are you sure you got AR500 steel? Edit to add: We do have a butt load of non-AR500 steel to practice on at our range. On that we limit ourselves to lead and coated bullets under 1100 fps. Not sure what steel they are made of but with time and lots of rounds they do show some damage. Edited June 11, 2018 by Flatland Shooter Link to comment

GrumpyOne Posted June 11, 2018 Share Posted June 11, 2018 There is no way that the steel is AR500. Link to comment
GrumpyOne Posted June 11, 2018 Share Posted June 11, 2018 Please, only one topic. I've merged the other threads into this one. Link to comment
Jeremyc_1999 Posted June 12, 2018 Share Posted June 12, 2018 It's probably not AR500. I work for a steel fabrication company and shoot lots of steel. True AR500 is good with anything I have shot at it. (don't have my 338 Lapua yet, but you can bet when I get it I will be testing) We do get mill certifications on all of our steel though so I know it is true AR500 Link to comment
