oeh I have had a 4x12x44 (or is it a 40? lol my CRS is terminal I tell ya) Nikon on a Ruger 77 7mag that I bought when I was a teenager in the late 80s. That was before Buckmasters and Prostaffs but would be a Monarch now. The scope is still brilliant, has NEVER given me one minutes trouble and holds zero as well as anything else on the market. I would go look right now to make sure what size it is but a younger cousin of mine that lives in another state has had the rifle for two seasons now (comes from a single parent home and he's in college so you know the story...) He just took his biggest deer a couple of weeks ago with a 300yd shot and the deer went down like a sack of rocks. I have dropped many deer with that gun at such ranges over the years. The zero was only changed as I toyed with handloads several years ago. I had some so strong I blew the necks and throats out of the cases yet the scope always held zero!

I have two VariX IIIs (a 4.5x14x50 and 3x10x50) and my old Monarch is clearer IMHO than either of the X IIIs,
