I am working on the redesign of a Leupold FXII-6X36mm scope and would love to get some idea of the dial knobs used on thier customized BDCs from the Custom Shop. No I am not changing to the 42mm, or S&B, or Zeiss or etc. I want to get the BDC custom calculated for my load and I want to use the German #4 recticles. This requires new dial knobs and I would love to see how large they are for clearance in a case etc.
