I shoot everything on 50 mag, but i've recently started turning the mag down for the standers.
It's swings and roundabouts,
higher mag is darker, but narrower depth of field.
Lower mag is lighter,clearer with less visible wobble, but wider depth of field. So it's personal choice.
If your chosen scope is dark or fuzzy, then a lower mag might work out better. I don't have that problem, but might gain more wind reading info at a lower mag (with a wider field of view)
