For something that's reliable,above average accurate and consistent without breaking the bank,Federal Auto Match has done well for me.My Ruger Mk III shoots it very well and always cycles.CCI Minimag HP is good for hunting and about as accurate.I also shoot some Green Tag,but it's a little pricey in the pistols.It's pure beauty in my Remington 541S.I have a good supply of SK match in the orange label box that's been disappointing in most of my 22's.In my Ruger Precision Rimfire with the can on it.about 1 round out of 10 is subsonic.The sub rounds will hit half an inch lower than the hypersonic rounds at 50 yards,and about 1 out of 10 will fail to cycle the Mk III.
