I have several leupold scopes
My newest one is a vx III 6.5 x20X50 which the custom shop put the M1 turrets on. Awsome set up.
My 300 WSm
has the same scope as you with the BC reticle in it.
It will be going in for a CDS turrets after hunting season
My daughters 25-06 has the 6.5x20x50 with the varmit hunters reticle
It will be going in for a M1 turrets after hunting season(my shooting buddies gun/scope is exactly the same and will be going in as well)
This past summer I have been helping a friend build a Remington CDL in 270 WSM
He put the 4.5x14 CDS scope on it Sunday he shot a 26.5 in 4 point at 740 yards
The way I understand it if you get the custom cds knobs they have stops in it limiting it to one turn the one that come stock do not have the stops.
I would not want the custom ones unless you are going to have a differant turret for each altitude.
