When I am serious about getting ready for a big match like the Chevy Truck Sportsmans Team Challenge I can put 5K rounds through my 10/22s in a month.

I bet my primary STC rifle has 25-30K rounds through it. It will still hold under 0.7 inch groups at 90 yards off sandbags with average ammo. With the big buck expensive ammo (Eley EPS Black or Red) it is under that by a little bit.
