The 204 definitely rides well enough to watch the bullet fly and hit. Or at least the Ruger M77-2TGT does that.
The Fireball with 40s in 221 makes it possible to self-spot as well. I can only imagine what a 17M4 or 17FB would do -- or maybe the 20 version of the Fireball?
Lots of options here, and it really is more fun to see the shock wave and watch the hit.
