New scope

I'm looking for a new scope to put on an fx boss...it currently has an fx 6-18-44 sfir...I'm trying to hunt squirrels, coyote, beavers, and whatever else....side focus just isnt cutting it...better from the bench...so I'm looking for a 30 mm scope...mil dot...at Least a 40 mm objective and at Least 3-9 variable zoom....no side focus....price range....I'm thinking not over 300...it is an fx so I'm not going to center point or anything of the likes...prefer something half way nice
