This is my segmented design meant to signify a target. I've sold loads of these, people around here really seem to like this design on the bolt action kit.
It's aluminum roof flashing and solder. I also use aluminum tubing for the "bullseye" and fill it with red nail polish(sorry, I don't have any pics). This looks good as well.
Thanks....I usually cut these at about 60 degrees and turn them down further. This customer wanted them a little fat so I cut the angle down to 45 degrees to try and keep the target shape closer to round.
