Target...? Which target ?
Beer can or groose at 50 can be open sight or 3-9.
More seriously , shooting for group or score from benchrest need some serious magnification.
All of my best groups came from 6-18 , 6-24 , 36 or 10-50 magnification scopes.
All of them were wearing fine crosshair and td reticle.
I also use one or two for load development for my hunting rifles.
While shooting for group size , impact point is set about one inch over aiming point ( in my case at least ).
Go with whatever suits you.
