I think it's a case of everyone telling each other how good they are.
Reliable? The single shot 22s were no more reliable than any other cheap bolt gun. I think the auto load 22s were a bit iffy.
Accurate? As accurate as any other cheap gun, I suppose. As long as you have strong enough fingers to pull the trigger.
Canadian made? You got me!
Well, am not approaching the issue with any pretensions, not care if something is stamped Cooey or Cooper.
The several model 60(0)s I've had shot as well as my CZ452 Lux (CZ 453 with set trigger and 6-18x scope does better but that comparison is a bit silly. Similarly the 84(0)s never had an issue (cannot say the same about H&R).
The single shots, 1s, 25s, 39s, 75s, 78s, 82s..., some had an extraction issue, fixable (thing Guntech walked me through that, no issues after that with any). Had similar issues with other single shots. You assert they are as accurate as any other, irrespective of trigger, then represent good value. Most Canadian boys had sufficient strength to pull the trigger based on sales numbers, perhaps more an issue with grumpy seniors
The semi-autos, 64s, 6Cs, 8Cs..., are not a true Cooey (not designed by Cooey). That said, are on par with the 10/22, easier to strip, and lower cost - perhaps that accounts for why they continue to be commercially produced (Cooey, Mossberg, Lakefield, now Savage 64).
Similarly the 71(0)s are not a true Cooey, were a blind mag version of the Winchester model 70 so no better / no worse.
No flash about them, some beauty in design and details (i.e. the captive knurled action screw), and simplicity of manufacture (the single shot design was awarded the Certificate of Honour in 1924 at the British Empire Exhibition in Wembley) but after 70+ years still seem to work at least as well (or better) than what is currently available in terms of getting the job done.
As H4831 facetiously illustrated, Cooeys work well enough to educate shooters (even the army agreed with that) and the reliability of which ndb86, gunsaholic, IMagius, Infantry-Soldier, spacesaver et al, speak seems to be appreciated in all sorts of circumstances (though suspect the bear may have been a squirrel).
The Cooper may operate with more panache but at 50 yards wont deal with vermin any differently.
