Re: Rimfire swinging targets
I whipped up this using scrap from my old work's laser...1/4" plate, cold rolled steel.
It works awesome with my Mark III pistol but my .17hmr did crater it at 100yds a bit which caused me to get some bits and pieces of bullet when I went back to my .22 so I don't use it for that anymore.
I also added some angle iron (not shown) to the axle to keep bullets from denting the tubing and causing the swingers to not swing.
I have since switched to this for my .17hmr (can't remember the overall size but it's 1/2" thick and works great for 200/250yd practice. You can see the impacts through the scope and then repaint, rinse and repeat.
