I have a hw45 in .177 and dispite my better judgment I got hold of a .22 barrel as at the time hell of a lot were saying the hw 45 in .22 was amazing, a week later the .177 barrel was put back in and that's where it's stopping! With the .22 barrel it was less powerful the accuracy was abysmal, I gave my 45 in .177 to one so he could have ago (he was a .22 fanatic) after getting every shot inside the 5 ring at 25m (2 handed and aiming at the bottom of the black like proper target shooting) he admitted he could not hit the target at 25m with his 45 in .22. He's since converted to .177
Hmm...there is an element to truth to this in the latter part of the post .
Its not so much the .22 per say, which often has a better firing characteristic in most guns, incl many pistols....but the balancing of the HW45 internals that makes this the case with this gun.
The compression ratio/ piston weight against transfer port design is about as bad as it gets.
They went all out power for the American market but oversighted firing behaviour massively.
The .177 will reduce the flow/bounce and try to re-address a balnce with the harmonics to some extent and this is reflected in a marginally better shot cycle.
Whats really needed is chucking out the mainspring guide rod/ piston weight, reducing the power down and arriving at something like the groups i shoot with my LP53....well nearly.
However, power is now down to my tuned Lp53 once you have done this.
ON top of the poor harmonics....which can be tuned out to some extent (opposite end guide rod and no piston weighting) we still have the rear moving piston issue to contend with but it is a bit better.

However, in contrast a Scorpion shoots beautifully in .22 and in contradiction to the jokey aspect of the first part of your post.....the Buccaneer , Shadow carbine derinatives dropped vermin all day long upto 25 yds.
Many shooters used the Bucanner as a close range ratter and even some pest control companies used it.
A first with a plastic stock and the 425 to 450 fps proving quite ideal in roof spaces etc.
We cannot mention Scorpion and vermin control here but same power plant ofcourse.
A stocked Scorpion as mentioned above could shoot tiny groups at 20 odd yards.
Different animal to a 45
