Or at least they are new to me. The blue color is really easy to see at the range and the grid is an all over 1" grid. I found them out on the web. Made by Lucid Optics. They come in a pad of 20 I think. The photo is out in bright sun.
Hmmm. I just checked online and the pack of 20 was $15.70 ish. Locally I can only by targets one at a time and I thought they were more than that. It has been a while tho...
I use cardboard and small stickers like the patches that come with the Shoot-N-See targets. I just pin the cardboard to the target holder with some loose nails as tacks don't hold very well.
It is nice because I can just bring the cardboard home to measure my groups.
