I came across a hw57 in 'tidy' ( just) condition, blueing fading on barrel, slight rust specs which I cleaned with fine w wool and oil, replaced missing trigger guard screw and now quite nice and solid, began to test in the garden.
It promised accuracy BUT it was louder than my 99 .
Was wondering if the breech might be leaking or is this bark to be lived with on a 57 (.22) ?
Would I be wasting time fitting a mod?
Any advice on this type please.
