I tried it at 100 yards, which was very optimistic of me, given my rather dubious eyesight. Note to self; If you think you’re going to shoot very well at 100 yards with this, get some glass. Either that or a very long white cane. Still, I believe the 3″ groups are quite do-able, and I had no trouble hitting a 3″ x 5″ gas cylinder cap, first try at that distance. Coyotes at 150 yds? I don’t see why not. Should be easy. A 4X scout scope is an option. I wish I had had one.
