Its to do with how the scope is designed , no clicks at all in the internal mech , detents/clicks on the actual knobs I think .
It has a internal cam profiled for the cal/load it was designed for ONLY .
Trust me its the only way to zero this scope .
The Marines usually carry the zeroing out at 300yds , ie with the E knob at 3 ( 300yds ) & 0 on the W knob , then undo the small set screws on both knobs , fire a group , then once the center of that group is marked , then they move the reticle onto that center of impact using the allen key thru the center of each knob , then re-tighten the small screws again , then fire again to confirm the zero is good .
The 900 inch ( 25yd ) method of confirming zero , is set for 300 & impact should be 5/8 inche high , or set 500 for a 2 1/4 inche high impact '
Later Chris
