Recently took delivery of a new 22 hw77 , I've done the usual deburr and tidy up of the internals , next step is to get a good fitting guide and top hat.
I've measured the stroke , it's quite a bit less than my 95/98 which clearly benefitted from a short stroke piston head , I'm left wondering would a 22 77 also benefit from a short stroke piston head and if so,by how much ?
Any thoughts on the subject.
