I recently purchased a Weaver K6 for my 7mm08 Kimber Montana and took it out to the range today to sight it in before a trip next weekend.
I am very impressed! Super bright and clear (to my eyes at least) and the magnification seems just right - not too much at 50m (I thought it possibly would be) and just fine at 200m.
Three shot groups at 100m were well under 1 inch and at 200m opened up to 2.2 inches which was ok given the wind was starting to get gusty. Can't wait to get it out into the field!
