This gives me an idea for a non-lethal round: not quite as soft as lead, the round will spin out to a nice pancake in x many yards, delivering a nice disabling smack to the target without penetration.

I like the Hornady .45 200grain ammo I use with my muzzle loader, fully jacketed, even inside the hollow point. Putting cesium inside that puppy will definitely make sure a deer drops quickly without suffering.

No its natural form is not, but a radioactive isotope of cesium is generated by fission processes.
