I had a Bushnell 4x banner that stood up to 25 years of pounding on a .338 Win Mag.before going wonky.also have one on a 30-30 and several on .22's and a 6.5x55[ so far so good]Seen the crosshairs fall out of a new Tasco 3x9 1/2 way through the first box of .270 shells.slowly upgrading to all Leupold as $ allows.Perhaps Meopta or Zeiss conquest?
