IMHO CCI Mini Mags are the best (but highest priced) in the gun you asked about. The Federal blue box (#510) and American Eagle counter part (both 40 grain) are also excellent. Federal also makes a "milk carton" box with 375 count that is slightly slower (1200 fps) than high velocity but specifically designed for Auto Loaders and is also excellent.

I stay away from Winchester and Remington as their quality has dropped and dropped over the years. Even during the .22 LR shortage I avoided buying those two brands. I did break down once (I was desperate I suppose) and I bought a few of the Winchester M22 black box and before ever shooting them the were re-called!
