Help with indoor backdrop for .22lr.

#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.

Depends on if it is sheet metal (0.1345) or US Standard plate (0.1406).
Sheet metal is usually easy to find. Plate in small pieces is harder.

The sheet metal shops use the sheet metal values and will look at you real funny if you specify a thickness.
The steel yard could care less how you call out the material.

lightsped, its not fair if you don't put a picture of the silencer .22 that your gonna be shooting so we have a better idea as to what you want.

Will be out at the club today around noon. Received a couple PM's requesting pics of the bullet traps. Will get them posted this afternoon.

Here's some pics of our backstop. The main one being used now is 36" long and 20" high. The one that looks old laying on the floor is our old stop, and the one sitting on the floor is another we just had made for bullseye pistol. Just a bit smaller than the big one that's mounted in the 4X8 sheet of plywood.

Works very well.

did you make the trap yourself? that looks nice.
It makes me miss the little welder that I have neglected recently.

Inverness - I love the picture, complete with sound effect "ping" lol.

honestly, I shot a lot of .22 in the basement at my grandparents house years ago. We just piled up a bunch of aspen logs and went at it. if you can't get some soft wood, phone books or a couple hundred brady bunch pamphlets would work well.
