Erich, if you can't hit a target (not a moving head in a gun fight, I'll admit) the size of an eye at 10 feet, you ain't tryin'. My little NAA is totally capable. I've head shot rabbits at 15 yards with it and shot a nutria the other day at about 15 yards with it out of my boat. I did shoot a little low on the first shot, got him on the second as he swam to the bank. The gun will put all its shots on a paper plate at 25 yards from the bench. 10 feet ain't tough at all.
These little guns are ammo picky. I tried a variety of ammo and settled on Federal bulk pack Lightening hollow points as shooting the best in the gun. Stingers tumble out of it, mini mags shoot way low for some reason, so low I can't file enough off the front sight to compensate. But, I was able to file it down to shoot Federal to POA and it shoots 'em well enough to actually take small game to limited yardages with. I've been shooting this thing for 25 years. It will, indeed, shoot that well if you aren't blind. My eyes ain't the greatest, does take good light to see that tiny sight alignment. That's one reason I wanna upgrade to a mini master for carry when I'm fishing or just afield and want a kit gun along.
The best thing about the little NAA is it is always there when an opportunity arises. You have to work with 'em to get 'em to shoot well and to learn to shoot 'em well, but that's not a lot different from any other gun. But, with the wrong ammo, they can be wildly inaccurate. And, every .22 has its own preferences.
And, yeah, I've won my share of matches over the years, but I'm no Jerry Miculek, never could make master class in IDPA. Actually, never got any better than a slow expert. But, accuracy wasn't the problem.
