We have a 1/2mile walking trail through the woods on the back of the farm. I cut a bunch of 3" X 5" steel plate targets and welded chain links on them then nailed them to the side of dead stumps with landscape spikes. Talk about fun! 3-4 guys walkin the trail plinking at those swingers. 3-400 rounds apiece in an afternoon and no bruised shoulders. and everybodys a better shooter because of it.
