RE: Leupold or Zeiss ?
jag both scopes are quality pieces but I believe you'll find the Conquest to be a better scope. The entire Conquest line is laserclear and of course the quality and durability are "Zeiss".
As for the reticle, you mentioned longrange shooting. Have you considered the mil-dot reticle? They are THE most practical and consistent tools for shooting over 300yds. I have yet to sell a customer a mil setup and them not RAVE about it after a season. Many have the reticles changed in their other scopes as a result!
Good luck,
RA
