I love 22 rimfires and have a small collection.. The older winchester rifles as long as they are in decent shape will shoot amazingly well. The Models 57, 67, 68, 69(a), 72(a), 75, 52,,,,etc.. Of the modern rifles the CZ 452 is the most accurate for the money that you can buy. There are others that occasionally do well but the CZ's are consistant. The Marlins are cheaper and shoot well but their poor trigger action requires either a good gunsmith or a replacement trigger, more $$$$. Few autoloaders come with good triggers and most won't allow adjustment to a really nice trigger. My favorites right now are an old M69A with a grooved receiver, a M52(one of the reproductions) and first string? the CZ 452 Lux. Mine is an older model LUX with an older weaver 3x9 paralex adjustable scope. I bought it new along with 2 more for the kids. Cleaned it and adjusted the pull weight of the trigger. The stocks are finished with what appears to be some type of lacquer and was replaced with TruOil... A 6x18 Redfield was used for accuracy testing and with remington subsonic HP's it'll stay under an inch at 100 yards. At 24 the groups were a hole.. at 50 they were consistantly under 1/2 and most times under 3/8's. At the time they were $175+/- . A nice older M69A is also a good choice as is the tube fed variant the M72. The 72's tend to be a bit cheaper and both usually shoot quite well indeed. The triggers on these are adjustable for pull weight, without too much problem and in my experience are usually good as is.
