Hi Guy,s I shot with Targetzero today, not a short amount of time either Approx 6 hour,s after several changes of rifle [swapping over] i have to say the Bushnell for me, the turret,s as Perry say,s are "his word,s" mechanical, it,s as if no lub whatsoever in them??Or the gearing seems rough cut?? Opticaly no better IMHO than the 10x40 bushnell, focal plane did seem to be bob on!! they are a good scope BUT worth the extra £,s, i,l reserve judgment......g.l.w
