Was looking at this scope to put on my new Savage 12 lrp 6.5 Creedmoor. If sighting the scope in at 100 yards, would I have enough adjustment for 600 yards? It only has a 20MOA internal adjustment. This also is with the NikoPlex Reticle. Would I be better getting the BDC Reticle? I happen to like Nikon's reticles, the NikoPlex with its thick bars pointing in to the thin crosshair especially. Or any other ideas.....target shooting only out to 600yds.

Thanks!
