/Back in the day...twenty five years ago,.I had a 541T, Kimber, Winchester 52B Sporter, Ruger 10/22 and Ruger 77/22 I shot Winchester, Remington, Federal, CCI, Eley, Wolf, of various "flavors" and believe it or not, the best O/A accurate rifle was with the off the shelf Ruger 10/22. And the weird thing (In the 10/22) the most accurate was CCI Stingers. Go figure...
It seemed to be a toss-up as to which ammunition the other rifles shot well. As I recall, Winchester LR, standard velocity was the most accurate.
Finding an accurate .22 round is often quite frustrating. Seems .22 rifles have a mind of their own as to which brand ammunition they prefer
Good luck
