Self sealing target - Do All Outdoors Lone Prairie Dog Target

I can't say I am happy with this product. Some friends and I were went shooting yesterday and we used this target as one of our targets. On the positive side we were shooting at this target at 300 yards with a 6.5 Creedmoor and the holes did seal or at least they did not leave big holes in the target. On the negative side this target does not swing when you hit it and the next negative the frame which supports the target needs to be bigger and taller one of my friends shot the frame and broke it. This would be good for a 22 or 17HMR at 100 yards but anything longer this is not what you want.
