I'm new to this forum and from across the pond, but I shoot in the WFTF Piston class in the states. I've made up a target that I haven't seen around before, and I thought I'd share it here if anyone is interested. It's basically an attempt to lay out the WFTF kill zone/range parameters on a shootable practice target. I ended up with the following:
One can see how I tried to show how the 15mm killzone is only used up to 20m, the 25mm is for up to 35m, and the 40mm is for out to 50m. I included conversions at the bottom of the page for us non-Europeans
Finally, I tried to show the KZ size and yardage limitations for forced position shots.
I've attempted to set up a google doc where anyone can download the PDF of the document, which should print to the right size if you format your printer settings correctly (i.e., to print at full-size, without auto-formatting)
I welcome any feedback, and please let me know if downloading doesn't work.
