Q：What caliber is 3/8 AR500 rated for?
A：A 3/8-inch thick AR500 steel plate, with a Brinell hardness of 477–555 BHN, is professionally rated to withstand most common civilian and light military rifle calibers. It effectively resists direct hits from.223 Remington (5.56mm) and.308 Winchester (7.62mm) at close range (within 100 yards) without penetration or fragmentation, making it ideal for shooting range target systems. It also stands up to medium-power rounds like.30-06 Springfield at distances over 100 yards. However, it is not recommended for heavy-hitting calibers such as.338 Lapua Magnum or.50 BMG at close range, as these may cause deep indentations or minor penetration. A 100-yard minimum safety distance is mandatory for range applications to avoid ricochet risks.
Q：Will 3/8 AR500 stop 308?
A：Yes, a 3/8-inch thick AR500 steel plate can reliably stop a .308 Winchester round under typical shooting conditions, thanks to its Brinell hardness rating of 477–555 BHN and high impact resistance. At a standard safety distance of 100 yards or more, the plate will not be penetrated or fragmented by .308 projectiles. It may show minor surface indentations, but this does not compromise structural integrity.
