338: The Zeiss showed shifts in POI between power changes,observed on the range.It got delivered to Zeiss who confirmed the problem.
The Swaro was part of an Alberta snafu on a hunt. It behaved in strange ways but also shifted POI between power changes and other stuff....weird.
There have been a few Leopold variables,IIRC 2 2,5-8's, two 1.5-5X, and one 1.75-6. Round count varied. IIRC a 375 H&H ate three of them.
No real experience to draw on with Euro Alpha glass, but the Zeiss almost sounds like too much torque on the rings.
The Swaro sounds like baggage apes - sorry your hunt was snafu'd. Especially since it was in my native Alberta. The weather etc. in November makes it tough enough, without having to resort to belt & suspenders pre-sighted spare scopes in qd mounts.
All these stresses on a scope can be cumulative and subtle .
Recoil is obvious because the shooter experiences it too, but mounting issues like ring torque and alignment have their own quirks to contend with.
Trust but Verify !
