I'm wondering what velocity (or RPM) it takes to shed the petals off a 350grTSX

Something about the thought of laser-beam .458 spritzers makes me giggle.
They're doing pretty well at 2700+FPS as it is, but flatter and longer range with mondo energy just sounds like fun.

...if someone else is buying me the rifle and reloading components...

Cheers
