Just my thoughts from having done this last year...
Heck of a lot of scope for a gun that will probably never shoot 250 yards. I know that the shotgun-specific scopes that are available are not exactly premium as I looked at any and all I could find, but I decided to go with a Nikon myself for my 12 gauge and the reticle subtensions work out very well with my gun and their BDC reticle. With the scope you mention you will sight in for 1 point (probably between 100 and 150 yards) and that's it. At the rate the slugs drop your effectiveness beyond 150 yards will be minimal.
I purchased the 2-7 which is more than good enough for the effective distance of a shotgun, and is also the power I've used on my 30-06 for almost 30 years.
Good luck in your scope search.
