I have one. I got a heavy barrel one last year for the kids to shoot. I skipped the 22lr and just went with the 17wsm. I replaced the plastic stock with a Boyd's All in one to make adjustment easier on everyone. I also added a BSA 17WSM scope (yep its a cheap scope), but works good enough, and their eyes are much younger. My goal was to have something to teach rifle shooting to them and that they could do small game with as well. Most likely, I'll get another one and set it up the same, with a different color stock just to tell them apart easier.
We have only had ours out a few times. Holds 1 moa in brisk cross winds, with the 25g rounds. I have not tried the 20g projectiles yet. Like to see how it does in some quite air.
