When that scope died more than 20 years later, I went to replace it with an “upgrade” that turned into 3 upgrades because none of the new scopes I bought would hold zero. I had a Nikon and a Leupold that would both regularly shift zeros randomly up to 4-6” at 100 just from a few hundred miles of washboard roads riding in the truck with everything torqued and loctited to spec.
I don’t have that problem any more. Do you? If you did, how might you go about diagnosing it? Would you blame it on wind, ammo, getting the barrel too hot, too much coffee, or just a bad day? If it happened in the field, and threw round high or wide on an animal, what would you attribute it to? How would you go about figuring out what happened and ensuring it didn’t happen again?
