On my Weihrauch HW97 K i am using a Richter Optics 3-9x40 Scope and can usually manage 1" groups at 40yds and 1/2" at 20yds. At closer ranges I find using any magnification over x5 and things get slightly blurred. This is using AA Fields or Exact Jumbo Express. I am thinking of changing the scope and at the moment I am looking at Nikko Mountmaster 3-9x40 px adjust costing £57. and the Leaper 3-9x32 Bugbuster at £135. I am using the gun mainly for plinking and some hunting. Any thought on these scopes or even an alternative for around the same money and am just wondering is there really £80. of a difference in quality. I am shooting air rifles only with a few months so any advise would be appreciated.
