Wow, after reading these threads I almost wanna cut up my 10/22 and melt it for scrap. Yet, somehow, the thing shoots 100% reliably (as reliable as any .22 semi auto) and is fun. How perplexing. I've got more accurate .22s, but the Ruger is a handy little fun rifle and 4moa is accurate enough for plinking and small game. Mine is iron sighted, just a plinker. My most accurate .22 is actually a sub MOA gun with RWS Target. It's a 45 year old gun built "the way they used to be in this country", a Remington M512X. I got it for my 9th birthday and I still shoot it. It's a bolt gun, though. In an auto, I suppose the CZ is probably the best, don't know, never fired one, but I'd be hard pressed not to run down to Wallyworld and buy a Marlin M60, or better yet, find one at a pawn shop for 60 bucks. They're everywhere. They're at least twice as accurate as a 10/22 in my experience.
If you really want a .22 to shoot, feed it decent ammo. RWS target is pretty decent and can sometimes even out shoot Eley which is much more expensive. If you're shootin' Federal Lightening, don't expect olympic quality groups from even an Anschutz. OTOH, I have an old Mossberg M152 built back in the 50s (also got when I was a kid) that is normally a 4MOA gun, about like the Ruger, that turned into a 1.5 moa gun with Eley Match. Amazing how it woke that old gun up. I'm not sure why, but it is nearly 7 dollars a box of fifty last time I bought it, been a while. But, heck, you pay that for CCI Maxi Mag, so for the accuracy, it's a bargain! Plink with the bulk stuff, get serious with the match stuff. I have some left here of RWS and I think some Eley. Might try it in the Ruger sometime, but I don't know how the action will function since the stuff is lightly loaded compared to HV stuff. It could make a difference in the accuracy of the stock barrel, though, worth a try. But, like I say, I bought the thing for plinkin', not target work.
