i have one, decent accuracy and functions fine. bought it because i wanted something to shoot CB shorts for when the squirrels hit my apple trees, accuracy was iffy for the most part with the CCI CB shorts i tried in it, but it does tolerably well with subsonic LR-HP's.
Have the magazine version of the XT22 and you're inquiring about the tube fed one. So, FWIW, find my version of the XT22 to be a decently accurate rifle....in other words, have no complaints about the one I own.
