whether your scope clears at the objective is simply a matter of choosing the right ring height, the one inch or 30mm difference doesn't come into play there...
I went with a Leupold Mk4 because of the world economic situation, primarily. It's a decent scope at a fair price, and it's coming from a company with better "staying power" than many of the smaller high-end optics makers fighting for their little niche in a dwindling market.
The US Army has chosen the Leupold scope for the day optic for their sniper rifles... http://twobirdsflyingpub.wordpress.c...-sniper-rifle/
If you don't want to spend close to 2 grand on a scope, but you still want a good, functional scope... the Bushnell 10x Elite works great, turrets are accurate, mildot reticle and decent glass... for around 200 dollars.
