#10 steel probably means 10 gauge steel, which I have in my notebook at 0.140625" thick.

From my other hobby, making armor. The photo shows 16 gauge (0.0625", less than half as thick as 10 gauge) and how 45 ACP caused a dent but didn't puncture. 9mm went straight through, though.
This was someone else's experiment, not mine. Not really an experiment even, as much as it was simply shooting stuff. He chose 16g because that's what we use to make armor a lot of the time, and this was probably a screwed up project he decided to blast apart.
I think 22lr would simply bounce off 10g steel even if it hit it directly at a right angle. But if I were building it, I'd put it at a 45 and go up to at least 3/16" ( 0.1875" ).
Which brings me to the point: if you go buy steel, use the decimal thickness in inches. There's a tendency I'm noticing recently to get away from goofy, obscure, proprietary American steel thickness measuring systems.
Oh, and I'm also in the "not where I eat and play" crowd, even though my range fees are more like $15/hr.
