OK, I've lurked long enough...
The 10/22 is an excellent rifle, and it can also be the biggest POS out there.
I've seen people buy a Volquartsen thingy, with a MOA receiver, lots of expensive go-faster bits inside, put a great big scope on the top, and still only have a 22lr self loader (and usually one that has FTF, FTE, and other problems). It has cost upwards of £1000.
Now I have a standard 10/22 blue barrel and it is just as accurate as the big money 10/22s and has never given me problems in regards to FTFs, FTEs etc. I have used it in competitions against the fully tricked up non-ruger 10/22s and it has never been left standing at the back. It doesn't look fancy, but it can still shoot as well as any other.
One thing I would say, to get the best from the rifle the trigger needs something doing to it. The basic would be to fit a target hammer. This I did and it made the world of difference and that was as far as I went on the fire group. I have filed the bolt hold open bit so it will slip off easier, but I'd never pay £12+ for the new part, if I couldn't do it I'd leave it where it is.
All I will say is many people have unreasonable expectations from the 10/22. It will never give consistent one-hole groups at 25yds (it'll get very close) if that's what you want then get a bolt gun - any 22 bolt gun as they are all as good as the next (just pay more for the finish). Chose the 10/22 for the disciplines it was designed for, not least of which is tincan plinking. Use it for mini-rifle, and the more action orientated gallery rifle events at the Phoenix and the like.
I have more 22lr rifles than I really need, and semis I have the 10/22, R22, Bremmer/M261 and Ceiner, and if the SHTF (and I could only take one of them to a GR competition
), it'd be the 10/22 that'd get the call up.
DON'T SPEND TOO MUCH MONEY ON ACCURISING A 10/22, HAVE FUN WITH IT, AND USE THE MONEY TO BUY A CHEAP BOLT GUN LIKE THE CZ452 (or any other, as they're all as good).
