I bought a scope for my M70 30-06 last year. I bought a 3x9x40 VX-III. I ordered it from the custom shop and got a post & duplex reticle. You can order from the Leupold custom shop IF the scope options are not available over the counter (ie: reticle, finish, or parallax setting). You save $$$ ordering direct from the custom shop (shipping is free). I looked at scopes that would fit a M70 long action and did not need extension rings (the M70 is a .375 H&H length). I found the VX-II 3x9x40mm,FX-2 6X36mm, the FX-3 6X42mm (a really good scope), the VX-III 3.5X10X40mm, and the Zeiss Conquest 3x9x40mm would fit and have enough eye relief for me. The 1" diameter Leupold scopes are the lightest in their class. A 30mm diameter scope will be heavier. A 50mm diameter objective lens will make your rig look and maybe feel top heavy. The Leupold heavy duplex is a good all around reticle IMHO. Not good for tiny groups at the range but better for hunting. The man that designed the Boone & Crocket reticle uses a heavy duplex for ranges up to 400 yards on elk and mule deer.
