for a 30-06....this would be my order....
1. Conquest
2. Monarch
3. Bushnell Elite 4200
4. Leupold Vari XIII
5. Weaver Grand Slam
If price is an issue....the Nikon Buckmaster line is great, I just bought one, and I am very pleased
My list of cheaper scopes (if a zeiss is not an option) would be:
1. Nikon Monarch
2. Bushnell Elite 4200
3. Nikon Buckmaster
4. Weaver Glam Slam
All cost about $300, or are in that price area depending on the models, but they are all vary reliable scope (or so I have heard about all of them)
Lawdog loves his Elites
Jon at the OpticZone loves his Nikons
and I have not heard a whole lot about Weaver's, but they make very reliable/nice scopes for target shooting, and the rimfire series is very nice, so I would exoect the same from their Grand Slam series
The Buckmaster has great light transmission for the price, and comes in some great hunting variable powers.....
hope all of this helps in your decision.....you should love your new rifle, I have heard great things about Tikka's!! (Especially the Whitetail Hunters edition, that has been discontinued!!)
