You've a good selection of scopes, but personally for the shooting distance you've mentioned I'd prefer a higher power scope.
Noticed the Grand Slam Weaver on your list....own a few Weavers myself that are all quite good scopes. FWIW you might want to consider a Nitrex TR1 instead of the Grand Slam. The Nitrex line was owned by same company that owns Weaver. Nitrex TR1s are basically Grand Slams, having same optics, internals and made in same Japanese plant. Nitrex line was discontinued, but its life time warranty is handled by Weaver. You can get a Nitrex TR1 in power range you wanted for $130 plus shipping here.
