I found a rifle range that I am VERY happy with* and I will be spending more time there. I've done the math on ammunition, cleaning supplies, and range time. I'm now looking at targets.

I did the math and even printing my own targets or ordering in bulk it seems like its a better use of my money buy a steel spinner target once than to buy paper targets over and over. Something like this:

The first thing I need to check is to see if my range will let me use thse. Since they regularly let people shoot propane tanks and appliances I expect it'll be OK.

Are these targets as simple as a bit of steel that spins around? Do I just find one that I like and buy it or do I need to think about safety and durability?

I intend to shoot my .22 Marlin and my Springfield 1911 clone as much as possible. I also have a Hakim (8mm Mauser) and a Mosin Nagant M44. Most of these spinners are for .22, but would the ones for larger calibers react to a smaller round well enough to show a hit?

Anyone have any experience with these targets? Recommendations?

Seems like an awfully long post for a simple buying decision, but no sense in spending my money before I get some free opinions. Thanks for reading and for any tips!!

*My range is Knob Creek near Louisville, KY. Great guys. Good prices. Nice facility. Close to home.
