I just use a 30x30" Morrell bag cover. We have some llamas and I had a bunch of old fleeces on hand so I stuffed it full of fleece. That works great. I've never had an arrow come out the back and if a spot gets soft, I just kick it a few times to resettle the hair. I shoot down my driveway. I have marks out to 60 yds and could shoot to nearly 100 there if there was a need.
