    How thick is the plate ? AR500 rings nicely when hit if hung properly , from the description it sounds like it was . 3/8 inch plate is enough that far out , the thicker the plate is the less it rings but you still get the smack when hit .

    The problem with the thinner plates and mild steel even at those distances is the steel gets dished pretty fast . Dished plates can send rounds in weird directions because of the curve . Reversing the plate to shoot The dish out will cause the plate to crack .

    With practice you can tell the difference between splash on steel from the bullet and dirt getting kicked up on a miss by eye .

    Not to sound like an idiot, but what is "AR500" steel? And where can you get it? Can it be cut and welded like regular steel?

    The AR does stand for abrasion resistance and so doe the 500. The number, in reality, has nothing to do with impact resistance. Most AR500 is good for 3000 fps impact velocity on down. At 1000 yards, most steel will be fine.

    MGM makes good targets, In fact, I know of a set of 10 for sale for $1000, that is $100 each!

    Best targets out to about 600, IMHO, are the MetalMans. Add a piece of 14 guage steel in between the hanger and the target face to get visual indication. Less $ than the MGMs too.

    Once you step out past that, you will probably want a bigger target, and the best indicators are the flash strobes. MGM carries them for about $135 per, and you just affix them to the back of a piece of static steel. Hit the target, the strobe flashes.

    I had forgotten about those... These target hit indicators work really well and you can see hits even in broad daylight.

    It can also be used on hanging steel but, if the wind is strong enough to move target, you might get a false-positive. For this reason, using it on static targets works best.

    I have one that I made myself for under $40 (the most expensive part was the flash). All that is needed is a mercury tilt switch (~$3 from Amazon), a flash with a PC connector (I paid $25 for mine but I am sure you can get them even cheaper on eBay) and a PC cable ($$$ depends on the length; you can find them for less than $10).

    This may sound kind of hokie, but what about a long range baby monitor? You'd be able to hear the gong ring anyway over the monitor if the wind didn't garble the mic up too much. They make them in 2.4 GHz which should be good for at least a couple thousand feet (3000 ft maybe since you'll have line of sight). It may be worth borrowing one to see if it would work.

    AR 500 steel is an abrasion resistant steel as somebody already said. It has high strength and toughness that gives it excellent impact resistance. It was designed for use in a lot of earth moving and heavy construction equipment for excavating and hauling rocks, gravel, mining, etc. You can buy it at a lot of metal suppliers and online. It's nothing special really but there are some other materials that would work and are somewhat cheaper for targets.

    Mechanical cutting and drilling would be a pain for the same reason that it resists wear. Laser or water jet cutting would be the way to go. Plasma cutting would work but you don't want to overheat it since it's a tempered material. They quench the plate and then temper it at the mill to reduce hardness and give it the high toughness that it has.

    Yep, you can weld it too but not like regular steel. You would probably want to use a hardfacing consumable, like what's used to repair endloader buckets, dozer blades... If you used a more standard weld consumable you could break the welds if your bullet had too much energy and hit the welds.

    AR stands for abrasion resistant and the number is the brinell hardness .

    It is a grade of steel that is typically used in mining / earth moving applications . Its hardness makes it work real well for centerfire rifle targets . It can be cut and welded like normal steel but applying heat to it screws up the temper so it isn't recommended for target applications as it leads to premature wear and holes . Quality steel targets are cut with a water jet or laser .

    The NRA center has a Steel Silhouette range that goes out to 1123 yards. No magnums and larger than .223 They also have the 1000Y HP range.

    Do call to find out if the range is available first.
    I see you running, tell me what your running from

    Nobody's coming, what ya do that was so wrong.

    Actually, the unknown distacen range, where they shoot the .50 competitions, goes out past 2000 on huge targtets. You need a good spotter on a good optic to see hits.
