I cannot ever recall being told by somebody they had a bad B&L

Well now you have, probably. I have an older 36X, the model before the 4000, where the slightest pressure on the ocular bell causes it to move, and the crosshairs point to a different place.
I did call the technical center, and they weren't terribly interested. I was told that I would have to pay a fee to have it evaluated. Don't remember exactly, but it was over $100, with no guarantee that it could be fixed. I was not the original owner, there was no warranty involved. They also mentioned that the company had changed ownership since that model was produced, and the new owners felt little obligation to the previous owner's products.
Well this was back in the 1990s, when serious stuff was done by writing a letter, and I never wrote one. Maybe the telephone tech was just having a bad day. I still shoot it from time to time, with the faint hope that when it moves under recoil (it must), it always comes back to the same spot. Odd, since I no longer believe in Santa Clause . . .
Anyway, I always check for that now. Not found it to happen to Weavers, but I'll allow they can have other problems with the adjustment mechanism taking a set, so they don't completely settle down until 4-5 shots after you've clicked.
I honestly don't know what scope is perfect these days. Never had a March. Am pretty satisfied with a newer Leupold competition scope - so far.
FWIW
