Have anyone used this reticle for any long range shooting or hunting? If so how did it do. I'm looking for a light scope for my "sheep rifle" (.300 wsm Sako Finnlight) and this seems to be the lightest scope I can find with BDC. Would the Swaro be better than a Leupold with a custom reticle or BDC turrent? I'd like to be able to shoot to 600 yds if I had to. What do you guys think?
