The steel wouldn't last long
The Bobcat Steel targets I own have had thousands of shots on them with zero problems. What kind of steel are you shooting?
Not so much the steel but the distance for a Steel Challenge Match, I don't want to be around when someone shoots steel at 30ft with a 5.56.
I can't attest for every club that has a steel challenge match but I'm certain that most of the targets are not AR500.
At steel challenge distances even AR500 can be deformed .
I'd like to raise a couple more questions on this topic:
1) given the recent carbine match at ACC which featured.30 cal rifles in 30 yard bays, is there a new position on this?
2) I assume the main holdup to running a 9mm AR pistol in a typical steel challenge match would be classifying it. I would propose running it in open division or possibly PCC but I'm not familiar with the minute details of each class as they relate to AR pistols. Also, it seems the most recent position taken by the ATF is that shouldering a stabilizing brace on a pistol is acceptable, which would make it comparable to a PCC.
I humbly await your responses! Thanks guys.
