I've just had a look and can't find any either. Wonder why there's none around
Like you said I've used the Hawke scopes for a while. They've been perfect on any springer I've tried them on, don't seem affected by the recoil at all. I think the most adjustment I've made to my zero this year was 2 clicks.

I would avoid 50mm objective for HFT, too many parallax issues at the very close and very far targets.

If I needed another scope right now, I would probably look at the Airmax 4-12x40 AO AMX
