I have the Saber and use the Bone Collector bag to catch my arrows. It allows the arrows to be pulled out of it easily. You can get replacement covers for it on Ebay. With it only weighing about 24lbs, it's easy to carry around.https://www.walmart.com/ip/Bone-Collector-BC-300-Bag-Field-Point-Archery-Target/986435943
On the cheap and the fly, I did make a stop out of cardboard boxes broken down and stacked together to be 2 feet thick, stopped them great, and I had them tied together so I could untie and more easily remove the bolts. This was with a 400 FPS crossbow.
A bale of hay. You can also cover a hay bale with a couple garbage bags & some duct tape to keep the mess down.
