This past few months I have been on a quest to find a scope, suitable for my LRH needs. Thus my purpose of coming here to ask the members their opinions. My rifle, a Rem 700 in 30-06 Ackley Imp has a light weight theme. It used to weigh 6 lb 7 oz when it was a 22" 30-06 w/ Leupold M8 4x. Now, with a more powerful scope for LRH I'm trying to keep it under 8 lbs, preferably under 7.5 lbs. I tried the Nikon Buckmaster 4.5-14 and the weight was acceptable but other things such as worrying about the repeatability was unacceptable to me. I never fully evaluated the Nikon but figured bigger was better. Thus my step up to the IOR 3-18x42mm. I freakin love this scope, the optics, reticle, repeatability; except the advertised weight is 22 oz and the actual weight is 29. The weight brought my rifles weight upto 8lb 3 oz. Thus my reason to sell the IOR. I've looked at the Nightforce and US optics but that would only exagerate my weight dilema. The new Nikon Monarch X is not available yet. It would meet the 8lb criteria but not the 7.5 lb critera. I hear Nikon's cust service is quite lacking and lengthy. Back to Leupold and either a 4.5-14 or 6.5x20. Undecided about a 40mm or 50mm obj lens. I realize the optics glass is not the same quality as the the European stuff. In a LRH situation, will the extra 10mm of obj lens diameter and 5 oz of weight make a differece in shooting big game out to say 800 yds, my self imposed limit? Is the Leupold repeatable and does it track well? Are the tough as nails? I'm plannng a Dall/Grizzly hunt for 2008 or 2009 and I sure don't need Murphy along for the ride! Zeiss? Great optics but I believe their range of adjustment is lacking. How is their 30mm lineup?
