But on the other hand it is always nice to have another gun in the rack. Any of the three you list should shoot good, the CZ has a great reputation, the Rem 504 should also be a good shooter and Savage has a reputation for accuracy as well. The CZ and Rem are much nicer finnished guns and a bit more expensive than the Savage. If it were me and money was not a factor I think I would go with the CZ or Remington. The Savage clips are not as good as the others, not that they don't feed, its the way they attach to the gun, the Savage has a protruding bar that the clip slides into, Marlin uses a similar system, just a little less refined than the others.
