I found that the #48 drill bit (.0760) works the best. It must be the drill Leupold uses to pre drill the hole already there. It's a tight fit when inserting in the pre drilled hole on the CDS knob. I just drill deeper and cut the pins from a drill rod. No need to use grease or glue, just tap it in with a punch (snug fit). I must of lucked out on where the pre drill holes on all of my CDS scope (27 of them) the hole are at the second hash mark off zero, When the pin is installed its at zero and when turned all the way up to where it stops, it's 4 marks off before zero. If need to remove just use a fine needle nose to remove the pin. I did this with my first CDS when they first came out, I drilled all of them same depth and made up a piles of pins from drill rod. I have 10 of the Cabelas specials waiting at the Hamburg PA store for me to pickup, so I don't know if those CDS knobs are drilled at the same place as my other 27 where.
Got any pics? Sounds good.
