I've had a first generation Nikon Pro-Staff 2-7x32 on my .22 mag. for about the last 15 years. It is supposedly a shotgun scope and set parralax free at 75 yards. It has worked very well at typical woods ranges where I use it for squirrels in the fall and in the open fields for woodchucks and crows in the summer. It has held zero just fine and I can consistently shoot 5 shot groups you can cover with a dime at 50 yards and sub MOA at 100.
