The Verdict is in
Because of this thread I went out today and bought a Marlin 795 for $139 AND 10% discount card, AND mail in rebate of $25. Drove to the range and put a few boxes through it and man what a nice suprise for the money!
Congratulations! Glad to hear this thread could be of help beyond my own dilemma of choosing a .22
I know one thing-and that is the trigger on an old marlin bolt action is WAY better than my new marlin 795,light, crisp and breaks with no creep-I think they must have held a contest to see who could come up with the heaviest trigger and awarded first prize to the guy who did and put that into production[that said-its the only thing I don't like about the 795-its very accurate]
While I haven't been carefully monitoring the used market, I will definitely keep an eye out for an old Marlin. And yes, the quality control of new Marlins appears to be getting out of hand. For anyone interested, a local dealer 'Sail' still has Marlin's stamped out of the pre-Remington factory.
...And seriously, it takes a fraction of a millisecond for the bullet to travel down the barrel, I don't think the extra fraction of a fraction of a millisecond has any effect on any rimfire round. And on the opposite side of the argument there is a case to be made for the added weight of a longer barrel making for a much more stable shot...

At the end of the day, I'm thinking barrel length in a .22 has more to do with intended use/purpose than it does accuracy. There will always be trade-offs.
Welcome aboard Fargal! For a fourth post, you picked a good one!
Sadly, I don't own any of your "shopping list". I have whittled my .22's down to a count of nine. Wasn't easy but, there's still soooooo many .22's I haven't tried yet!
Any on your "list" are sure to please. I'm a frugal shooter so, unless I inherit (doubtful...long line of frugal shooters) a CZ or, Browning, odds are against my owning one. Don't discount the suggestions of "older" .22's ...they are affordable and, have many years of "testing" to back 'em up.
I also side with Grizzlypeg in suggesting you purchase new as, that might keep the market fair for us frugal shooters. To play fair, don't get upset when a Mossberg, Marlin or, Cooey (among others) happens to be on the same range as you but, seems to "outperform" a shiny new rifle....partly because, being your first .22 [I'm guessing] you're "fresh" to the sport. Partly (I hate to sound so old), "they don't make 'em like they used to"....
I doubt anyone here (CGN) will deny the pleasure of shooting a .22!
Thank you for the welcome and your response! Yes, I can't help but see the writing on the wall, I'm likely to own 3+ .22's within the year (a semi, lever, and bolt action).
While I do sometimes check out the EE section, I have more or less decided on purchasing new primarily because i couldn't spot a lemon if my life depended on it. I just don't know what to be looking for. As you've pointed out, there are plenty of old rifles out there (and some rusty cooeys) that are outstanding.
Almost forgot!
If you are inclined to go used, look for a Winchester 69A, (lots of patience and luck required). These old rifles are sleepers here in Canada but in the US, they are quite prized by both shooter and collectors and their prices reflect this.
Thank you for the tip! I'll definitely watch out for them and with any luck may even pick one up.
At this point I'm pretty much decided on a CZ 452

. After all the positive feedback on this .22 I'm confident that if there's a problem with it, it's probably me, not it

. Shortly after purchasing the CZ, I'm thinking I will pick up a Browning SA-22 -> they are amazing little take-down semi's with great fit & finish.
Thank you for everyone's feedback, ideas, and comments, they were much appreciated as I was quite lost in the foray of .22's out there. Hopefully this thread has been of help to others facing a similar quandary.
Catch you on the range!
