Sorry that just does't line up with what I have experienced.
I can appreciate that John, but here's what I have experienced.
First, I have shot well over half million rounds at steel. But it's not so much what I have shot as what I have been present for. Between ROing, training partners etc. I have been present for millions of rounds on steel. Most of these have been steel challenge or cowboy and a small percentage being IPSC.
The worst:
Early IPSC matches with plate racks and targets with bases welded to them.
Cowboy shoots with pitted steel, you will get zapped a lot! Sometimes they had very bad angles as well, caused problems, especially with shotguns. (I have not shot a cowboy match for 6 or 7 years)
Steel Nationals this year in Florida. Plates had a hook coming right through the center, very bad.
Those are the worst I can remember, but what they all have in common is flawed target design.
Steel Challenge as targets flat to the shooter (although drawings do not show it) and no splash coming back to firing line.
Slavex has the best targets for steel I have ever seen, the only improvement I could see for those would be to make them adjustable, but if your range is flat, it's not much of an issue.
