Red & yellow work good on white, not so good on brown, still hard to see poi.
Found Printtargets.com and set up a fine line target with crosshairs. Ordered one from Rubberstamp using the 1 5/8" diameter stamp for a 1 1/2" diameter image. I didn't see exactly what was sent and I received this.
The longer crosshair is 1 1/2" long. The four concentric circles are about 5/16 in diameter. Not exactly what I was thinking for a 50 yd target. They did their best to include all of the image I sent them, guess I shoulda filled in that little box about special instructions. Rubber stamp champ accepts only PDFs for image reproduction; Printtargets.com does that for you; Rubberstamp can manipulate the image, be sure to give detailed information when ordering about what you are trying to achieve .My mistake came from not being familiar with the printtargets use of scale. After speaking to a rep at Rubberstamp about it all she put me in touch with one of their techs and we ironed out my mistake. Printtargets can do most anything,I should have eliminated the crosshairs. I use pieces of boxes to stamp on and have 30,40 and 50 yd stakes(no trees here) to attatch them to for my home range. One 1 5/8" diameter stamp, one refill for 10,000 imprints, shipping, about $35. My experience, priceless! Tom
