The 20 inch lightweight contour barrel of the 11 LWH will produce lower muzzle velocity and more flex than a 22 inch sporter profile. To achieve the same accuracy, you'd have to limit the range with the LWH.

What I'm suggesting is that you wouldn't use a short (20 inch) lightweight barrel to shoot to an extreme range. So, you don't lose much, practically, by going from a 9x power scope to a 7x power. If you're buying the LWH for its light weight, you might as well get a lightweight scope as well.

Having said that, the Redfield 3-9x40 is only a couple ounces heavier than the 2-7x33, so it's really not a big deal. Whichever scope you get I'm sure you'll enjoy it.
