Designed these to print on half-sheet shipping labels so you can just quickly stick them on whatever you want. High visibility and I like the full crosshairs to aid with alignment. Red circles are 1" diameter, green circles are 1/2". Blue dots are 1/4" and good for test shots.
I drew up these targets to feature a pronounced cross hair to get the most consistent groups with minimal canting and to help set up scope level as it applies to " shooting across" at different ranges. These are also nice for shooting 10 shot groups while looking for flyers since the center can be totally shot out without losing the cross hairs as your aim point. Pin them up down range using a level. I use a cardboard box full of rubber mulch as a trap with a clipboard taped onto the front. Put duct tape over the holes in the clipboard when it starts to get shot out to stop leaking, which doesn't really happen anyway since the rubber mulch is so coarse.
