Okay. I can see why you would want to change zero at a range. I started shooting gophers a long time ago. Most of our gang had never even driven past a proper gun range in those days. We just sighted the little old rifles in and sallied forth. I have seldom ever changed the settings on any of my scopes. Many ears ago, a good old-time gun shop in our area drilled and tapped a Czech 98 for me (yes, I know), put bases on it. I asked one of the brothers who owned the shop if he would have a scope I could afford. He reached under the counter, rattled around in a cardboard box and came up with a scope. He looked through it, banged it on the counter a couple of times, looked again, and says, "This one should be okay. $10." He mounted it, sighted it in for me. It is a Fisher-Dietz 4x. It never did have caps since I bought it and I have never had to fiddle with the crosshairs. I had it re-chambered to 8mm-06. I have taken quite a few whitetail with it.
I have used the old rifle off and on for the last 40 years, still in it's original ugly old cut down laminate military stock. Weighs a ton. but it is like an old friend, carrying lots of good memories.
