A few years ago I tested a whole bunch of different ammo in a few of my .22's. The best fast ammo I tested was the CCI Velocitors. I got 1 inch groups at 100 yards and the drop at that distance was pretty decent compared to some of the other ammo I tried.

That does not however mean it will shoot well in your gun. Most guns are a bit picky about what they shoot well and it pays to test different ammo, which is what I was doing.

I don't even own a .22 any more though. I have a 17HMR now and for any more than I shoot a rimfire it suits my needs well.
