Plus they get a little 'lively' when pushed to near the legal limit they only weight, after all, similar weight to a BSA Meteor. I once bought a s/h 55 (.22) that was well worn in that consistently did over 13ft.lbs. m e with a variety of pellets. I soon changed the mainsprings to bring the power down to a more reasonable (and legal
) level.
With the aid of a spring compressor they are a very easy rifle to strip. Undo the screw in the scope rail and tap it back when you release the spring pressure. Careful on re-building that you dont cross thread the retaining bolt/stud. The first few photos may help with the strip
