Buckfever,
I have an Elite 3200 1.5x-4.5x-32mm Firefly on my .375H&H Mag and it has held up perfectly with no problems whatsoever. Would you believe that I get 1/4" groups and better?!?!?! It's true, so at least we know that the scope holds up very well.
The only thing that I don't like about the firefly reticle is that it is too thick for my taste. Other than that, you really can't beat it.
Plus, remember that this scope has rainguard which will definately be invaluable to your moose hunt where rain, fog, etc. are common.
