use it on 10 x for ratting and scanning or quick shots and 50 mag for long range checking out the next field shooting at over 25yrds / sniping
never use the in between mags just 10 or 50
using teh Mil dot with 177 at 12ft lbs the trajectory matches the mil dots very will at 50 x and scales at 10 ie 5 spaces and 1/5th the mag
or 177 i find at 10 mag 8yrds is 1 dot down
cross hair is 12yrds and 40 yrds
and 1 dot down is 55yrds
so for FT ever thing fits 2 dot spaces
Scope only has the std mil dot ret the extra lines just show the range to the dot and the mid point between dots ( as its easy to guess 1/2 way)

if i zoom in to 50 mag
its like this

heres a std 40mm FT kill zone ar 30 yrds on 10 x and on 50 x ( did this years ago before there where camera mounts so its just holding the camera giving a poor image)
i prefer aiming at a large dinner plate
