Personally, I consider pretty much any scope "springer rated" and just have at it. But, I don't have any harsh shooting Magnums either so keep that in mind.
Funny, the ONLY scope I've had serious mechanical issues with was an Airmax. Biggest pile of crap I ever put on an airgun. The AO shifted the POI all over, turret adjustments would stick, and finally wouldn't hold zero. Sent it back to Hawke, they told me it was fine and just sent it back. In the trash, and I'll never own another Hawke. Was never impressed with their glass anyway, and certainly not their warranty.
My point is, most scope manufacturers don't have any idea about a spring piston airgun. So their claims of "springer rated" may or may not be pulled out of thin air, and I wouldn't count on them to back it up.
My advice, buy a scope, any scope, mount it, if it breaks send it back and tell them it was on a .308 Ruger.
My opinion is if a scope breaks on a 12fpe HW97K, it's not a very good scope anyhow.
