Den, that is ingenious, and looks like fun. It'll also run with a .22, or even a pellet gun.
Hey ! :
Set the Star up in the Back Yard
Ran my Umarex Colt .177 Pellet at it
Just shot little tiny holes in the Clays
Shot three pellets as fast as I could sight and pull the trigger; 12:00, 10:30 then 01:30 all hit the center of the Clay...Nothing but little tiny holes
Nice shooting for three quick shots hits, but no broken Clays
TOTALLY BUMMED
It took about five random shots around the edge of the Clay to get one to kinda break enough to fall out of the Ring
I'll have to try .22lr then 9mm first chance I get
Thinking I may have to cut an inch or so out of the top to allow the Ring to have less grip on the Clay
Or give the Ring a Clamping action when the Clay is hit
It's still a work in progress folks
