peartree,
First off,
WELCOME ABOARD!! I'll tell you what - I have an Elite 3200 1.5x-4.5x-32mm Firefly on my .375 H&H and I love it. As far as toughness is concerned, the 3200 held up to about a box of 300 grain ammo with no problems. In fact, I got 100 yards groups under half and inch! :eek: A .350 mag is no slouch, but then again it's no .375 H&H either. As such, the 3200 - which costs about $200 - is tough to beat.
Now, I do have a complaint, but it's not really about the scope, but rather about the magnification. My .375 is a Winchester Classic Stainless with open sights. In fact, the front sight is huge with a hood on it. As such, at 1.5x, you can clearly see it through the scope, and it kinda bugs me. You really can't see it past 4x. I mention this because I know that the Remington 673 also has a huge front sight. As such, it may also bug you too.
If you can afford it, get the 4200 1.5x-6x-36mm. The 4200 has better glass, and, with up to 6x magnification, you really shouldn't worry about seeing the front hood.
If I had to do it all over again, I'd probably get the 4200 model for the extra magnification. I got the 3200 because 1) I wanted to try out the Firefly reticle, and 2) money was kinda tight at the time.
For the money, you just can't beat the Elite 3200.
