I have a .223 N.E.F. For the money, it can't be beat. It's light weight for carrying if you have a long walk. The only bug is the ejector. You have to take care when loading. If the shell doen't catch on the ejector, it will stick in the chamber after firing.
I called up and shot a double last year with mine. The coyotes were only about 30 yards away. After the first one hit the ground, the second couldn't figure out where the shot came from. I had time to reload and get the second one too.
On another occasion, I only winged a coyote and had to come back with a second shot after he had covered 250 yards. You can see this one and the rifle if you go to northmosportsmen.com/hunting/predator
