You can't go wrong with a leupold, if you can afford it. I also liket teh Bausch and laum scopes with the rain guard. I personally use a Simmons 44 amg on my 7MM mag and haven't had any problems with it. It is a 3-10 power. Simmons also makes the Atec which is a very nice scope aslo. Simmons is les expensive than the other 2, but are very good scopes. I wouldn't hestitate to buy another Simmons. Mine has taken some pretty nasty abuse for a scope.
