All that said, I have a question. Has anyone done any testing closer than 10 yds. using handguns and AR500 steel without a spalling barrier?
My "informal testing" (aka, observation)
Earlier this year, I purchased some 10", 12", 18x24" steel plates (AR500, 1/4" thick) to practice Steel Challenge stages.
Several of the stages require target placement at 8 yards from the shooter.
My practice partners and I shoot either 9mm (Glock 34) or .38 Special (S&W something or another).
We use coated lead bullets from

We use wood target stands placed upon grass covered ground.
After over 30,000 rounds at these targets (20% at 8 yards, 80% at 10-35 yards), still no splatter onto any of us.
I attribute that to the hardness of the steel, the smooth surface of the plates, the downward deflection of the plate upon bullet impact (spring loaded from top bolt), and the grass covered turf.
Judging from the looks of the wood target bases - the bullet splatter seems to deflect straight down to the target stand base & grass turf.
Contrasting experience - using different plates, mounting system, and ground/wall surfaces...
At our club's steel plate matches, we use a mix of AR400 & AR500 steel plates.
These plates are center bolted (flush with plate) to the target stem, and provide no "give" when struck by a projectile.
The ground is more gravel based, the side berms are concrete, the distance is 8-12 yards.
The calibers are 9mm, .40, .45, .38 Super. Lead, jacketed, JHP's are all used.
At these matches, it's not out of the ordinary to be hit by a frag every once in a while.
Probably 99% of the time, it's just a harmless fleck you feel on your leg, arm, cheek, or something that lands on your hat.
Sometimes, it's a bullet jacket "frag" that sticks you enough to draw blood.
My observation...
The quality of the steel (hardness & surface smoothness), the proximity to other deflection points on the range (ground, walls), and the downward angle or "give" of the steel, in addition to the distance from shooter to target - makes a difference in the "fragging" level (spalling) experienced by the shooter.
And ALWAYS, ALWAYS, ALWAYS wear quality eye protection when anyone on the range is shooting steel targets.
