Picked up @shallowforks old Nikon ED50 a couple weeks ago, and dang is this thing sweet. I haven't had the chance to get out and do any proper scouting, but I happen to live in sight of prime sheep country so I have gotten to play a bit. I took the scope out to get my mind off work for a few minutes, and spotted a group of sheep in about 60 seconds. Put a pin on the map where they were standing, and surprised myself that it was a clean 5 miles from me to them.
Not half bad for a 1lb scope! Can't wait to get boots on the ground for the high buck.
