Not the one I had.
Bought a marlin m60. Most accurate gun for the money I've used. Got mine for under $200. Sr22 I had shot 3"+/- groups at 30 yards. Marlin was average .5" at 50 yards with mini mags and cci blazer 50 round boxes.
Sr22 $600, marlin m60 $180.
Maybe the 10/22's form 20 years ago were better but I wouldn't be buying a new one. Local shop sent one back because you couldn't even pull the bolt back it was so rough inside.
Again, this...
It amuses me that when I made my initial comment, the first two reactions were to insult me, instead of the position I took.
Older 10/22 had fair accuracy, never "great" out of the box, but fair.
The 10/22 that Ruger has cranked out to make a buck off the gun panic in the states over the past few years... Notsomuch. You might get a good one, or you might get a crap one. It's really a roll of the dice with them. Really inconsistent production and QC. The fact I had to take a Dremel to buff out the overcasting inside the receiver of a brand new 10/22 I bought last year just to get it to function properly, speaks to the sh!ts not given by Ruger over the past few years about the quality control they apply to the line. Poke around a bit online and you'll come across a lot of people who've had similar problems.
If you decide to go with a 10/22 as a platform, spend the extra $$ and go with a Dlask or other aftermarket, higher end build. Those will definitely shoot better that most of us here can.
As for the CZ's 512, 452, 455... You can spend a long time searching the internet trying to find someone who's gotten a bad one and not find anything. They're really high quality builds, especially at this price point. For the 452/455, other than putting a scope on it, the only mod you might consider is the Yo-Dave trigger kit.
Anyway, I know the 10/22 fan crowd is even more ardent that the AR-tards, so I'm farting against the wind by saying it. But I actually own both a Ruger and a CZ. I've spent the time printing groups on paper. And if you're after accuracy past 25 yards, and a quality rifle, it's not even a question as far as I'm concerned.
Buy a CZ. You won't regret it.
