HW45 Poor performance. Is there a service guide?

[Jweaver]

I don't know where your located but perhaps your gun is one tamed down for some markets like mine, Canada where the legal limit
is 500fps. Like I said ,my .22cal HW45 gets anywhere from 410-467fps, my HW75 .177cal only gets up to 360fps.
Try a lighter pellet for more muzzle velocity?
I wouldn't consider at your guns performance, that it would be defective in any way?

I am in the UK, and we are allowed 6ft/lbs, so at 3.8 I think its not right...

Are you saying that in Canada, you are limited to FPS, not Energy? How does that work?.. You could put a heavy load in a powerful gun and still be under 500fps, even though you have a HUGE (lethal?) amount of energy... Do they literally only limit muzzle velocity? Or is this at a specific projectile weight?

I am not too worried about velocity.. Of course I could go for a lighter pellet if I wanted a faster shot.. But I want to be sure that its delivering the correct amount of power and if its not fix it.

In a way I hope that my new Chrono confirms my findings as I would like to take the gun appart anyway, to learn how to strip it and fix it IF something is broken.
