You may need something heavy, like a log, to keep the stand base from blowing over in gusty winds. Something like that happened to a couple trying to shoot their pistols during the latest TCA MG shoot. We found an old log and gave it to them.
I have used these and just screwed them to the side of the target frame. then push it in the ground. they will also still fit in the metal/concrete tubes at the 25, 50, and 100 yard marks
Made a pvc stand, and agree may need weight, got a bag of sand to put in the pipe if necessary. But will need to seal the items together when I am ready, in order to do that.
I use a PVC stand like the one pictured above, just a bit modified. The base on mine goes all the way around instead of only halfway. I don't spike it down, the full base keeps it from blowing over. Ihaven't had any issues with it blowing over and I have been out there on days when I have seen other people's targets laying on the ground while mine was still standing.
