Since I am sending my Combro chrono off for a service today, I decided to test my HW45, after all, if I 'missed' and broke the chrono, it wouldn't be an issue as they replace all of the broken bits for a flat fee (£7.50).

I was disappointed that it only shot 467fps (verified over 3 shots), with an 8 grain pellet, which by my calculation is 3.8ft/lbs.

I have a Polish Chrono on order, so will be able to verify the result, but I am pretty sure its right.

What can I do to restore the power? Is there a guide showing how to strip/service the gun?
