How to make a practical paper target holder that would go in and out of my car handily was always a problem for me, until 3 or 4 years ago when a TUAK reader suggested another use for chicken wire.
I’ve been dragging this around in the Jeep for a couple of years now, as needed, and it works great. PVC is an obvious material but leaves you with the question of how you attach the target. Chicken wire works great. If wind is an issue it would be easy to fill the legs with sand or, more permanently, cement while still leaving them detachable.
You will naturally shoot out the center of the wire. This turns out to make no difference not only because you’re not attaching targets to the center anyway but also because clothespins work on broken wire as well as on unbroken.
