most of my shooting now is with a CMMG dedicated upper on an AR for a short range 3 gun match and a run and gun carbine match....accuracy is not critical ,even on reduced size USPSA targets, though the 2" Team Challenge targets are challenging at 35yd, so I typically shoot Fed AutoMatch as it is ususally available through Palmetto State Armory... when I shot the Chevy Truck Team Challenge, my 10/22 was tuned for Win Super X as that was what my SW M41 liked... when I shot IHMSA .22 silhouette, my High Standard Citation shot CCI mini mag pretty well out to 100yd and in those days was readily available
