My buddy was pretty impressed that his 22-250 loaded at around 4,100 fps cratered my AR500 plate pretty good. Much better than anything else we fired at it that day.
I told him to shoot paper or yotes with that thing from now on because he was fn up my steel.
I thought AR500 was pretty close to the same as Hardox500 but it must be somewhat softer, those bullets wouldn't even scratch my Hardox500 gong's
Yeah, that's what I thought as well. Your Hardox500 has the same Brinell hardness as AR500 plate. 460-540 vs. 470-530 (Hardox500). The reason they call AR500 plate, AR500, is because it has a Brinell hardness of roughly 500. The same can be said for Hardox500. They are both thru hardened and heat treated the same way, but not composed of the same alloys.
