I recently purchased nine large bag targets that came with modified "T"-posts to hang the bags (see pic below). The bags are stuffed very tight, and triple bagged for durability. They have been outdoors continuously for 10 years but as you can see are still in great shape.
Last weekend my buddy, Chris, and I retrieved them from the previous owner, and with the help of another buddy, Ronnie, spent last Saturday setting up a course in a wooded draw near my house.
On sunday, Walker and I shot the course for the first time. We set the course up well, being able to shoot coming and going. Shots range from 12 to 25 yards.
Bag and T-post set-ups
By climbing into the crotch of the dead tree you can shoot 3 bags. Due to topography, all shots from the tree are from an elevated position; it is very similar to shooting from a treestand.
