Here's another vote for the Nikon Omega.

Your question about it only being good for certain loads.
If you learn where any load hits then there are two ways you can adjust to it.
One is by shooting and learning where it hits with the load you like.
The other is related to the way I use PBR [point blank range]
If you adjust the height of you hit so your 200 yard is on then you may be an inch or at most 2 inches high at 100 but will be on close enough so a deer will never live to find out the difference.

hey i noticed truglo has a scope thats good out to 300 yards and lets you tune it with any load

Look at the Vortex Diamondback line. Great clarity and very crisp. Warranty on these are second to none.

I have a Bushnell Banner Dusk to Dawn 3X9 ML Scope on one of My ACCURA's, it works Great! I got it 2 years ago from Cabela's for $89 and it's as good as My Leupold Ultimate Slam ML Scope and My Nikon Pro Staff. For the money you cant go wrong.

I'd read this before you buy anything. http://opticstalk.com/forum_posts.asp?TID=21176

It's not that the Prostaff is a bad scope, because it's not. It's just that you can get even better scopes for not much more.

I'd go for a Burris Fullfield II or Vortex Diamondback if it was me.

That being said I have a Leupold VX-I on mine, but I really don't like it. The reason I have it is I replaced it on my rifle because like I said I didn't like it. So I had an extra scope so just put it on my muzzle loader instead of having to buy a new scope.
