i have a hay bale wall set up behind my target. i set it all on pallets to keept it off the ground and so it would sit nicer..i have the hay bales at a 90degree corner. i have 6 bales. 4 on the bottom 1 on each top side. i need 2 more for the top..1 bale wont stop it...i have my target propped up on the 3rd pallet that sits on the 2 back pallets. heres the only pic i have...i cover it all with a tarp when im not shooting and take my target in the shed..i just dont want that cotton in the bag to get wet though they claim to be weather proof..try wetting a bag and let me know what happens! lol
