I have tried various brands of 22 HP hunting ammo in my Ruger 10-22 T rifle and found the Winchester HP PP to be the most accurate. I also found X22LRPP to be accurate in my other 22 rifles. The published MV is 1,280 ft/sec, ME is 146 ft/lb with the 40 GR HP bullet BC at 0.110 . I zero my 22 RF rifles at 60 yards which give me a point blank range to 80 yards that I like for shooting prairie dogs and small game.
