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 !


No not too much stress the rings with the Zeiss. I spoke with Bruce Cavey who was President of Zeiss NA at the time. He had me ship the scope.

His tech guy called and said they had tested the scope here in the states and I was right....it shifted POI between power settings. They returned it to Zeiss over in Europe for analysis and sent me a new scope.

The Zeiss is not the first variable power scope I've seen that shifted POI between power settings....it's more common than you'd think but better today than before.

The Swaro....I think it was defective from the start. I am not the only one to have problems with that particular model.

Leupold variables are.....Leupold variables. I have gotten to the point I that I can't make myself spend the money on them any more. I'd rather buy a fixed 6X than a VX."whatever".



The 280 Remington is overbore.

The 7 Rem Mag is over bore.
