However if you want to shoot birds these can offer too much penetration and go through which isn't completely bad but can cost you a clean kill. For my gun these pellets have proven to be the most effective penetrators and most accurate pellets I use.
For a more destructive round that will match the exact placement I'd go with the Gamo Red Fire which practically shreds itself once it enters. It is a lighter pellet but I found it will shoot in the exact same spot without correction. So I'd recommend those over these for expansion if thats what you're looking for.
They are more expensive however. Since the Red Fires will hit the same spot without correction, the Crosmans are good sighting rounds for them as well and could easily be interchanged for different game.
