I've never understood why scopes have mildot reticles and MOA turrets. I used to think there was a MOA turret mountain somewhere that manufacturers were using up before starting on MRAD turrets.

You end up with something like a 3-9 SFP Hawke scope with a mildot reticle that they claim to be correct at x 10 magnification (is it half mildot at x5?) with MOA turrets. Fortunately I was born in 1966 so I'm used to mixing metric and Imperial units.

MOA turrets are a bit more precise on zeroing as 1/4 MOA is a smaller angular adjustment than 0.1 MRAD, which is probably better for airguns which tend to be used on small targets at very close range.

MRAD is better for human sized targets at distances of hundreds of metres or correcting artillery fire at kilometres.

Still seems strange to mix the two on a single scope though.
