I've found that 22s are much more picky about ammunition than other rifles. I have a Kimber 22 rifle that will shoot 1" groups at 100 yards.
Of course you have to use match ammo and set the scope for 12" high and wait 7 seconds for the bullets to get there.
But, my CZ will shoot with any other rifle all day.
Even my Browning 22 Auto will hang with most bolt guns if I have the right ammo and do my part.
The thread was interesting to look through.
An Internet forum is like having a friendly conversation over a drink at a local tavern.
Some guy at the end of the bar always has to stand up and shout something that makes no sense at all.
