I picked up the 4-12x40 Swift Premier a few years back. I had it on my A-Bolt 7mm. One evening I got into a sleet storm that turned into a heavy snow, and by the time the big buck I was chasing showed himself at 50 yards I couldn't see thru that scope any longer, so I pawned it off on an internet forum.
Hope your scope turns out better than mine did!
I am looking forward to seeing how this rifle shoots, I've been eye-balling one for a few years now!
