Rifle Scopes Simmons 6-21x mil-dot calibration

Re: Simmons 6-21x mil-dot calibration

Measure out and mark 36" at 100yds. Adjust the magnification until it's exactly 10mils on the reticle. That's going to be where it mils.

I don't care what kind of scope it is and what the manual states. Always verify at the range.
 
Re: Simmons 6-21x mil-dot calibration

Appreciate the info BB, but i need to know if the mil is "rough-cald" at a power less than the highest so it can be applied at a higher power and smaller subtension. I would also like to know if they use a base-ten mil at .2 mil for the dot or if it's a 0.125 system.
