Minor additional point - if you're trying to create dangerous shrapnel, don't you pick something angular & sharp like crushed gravel, nails or even hex nuts, instead of nice round ball-bearings?

Better range/higher velocity with something more aerodynamic, maybe?

It's the energy that matters. A famous military anti-personnel mine, the claymore, uses spherical shrapnel.

I guess that lines up with the other reply about the shrapnel being aerodynamic, something with less air resistance will have more range.

Quite probably, and it'd probably be cheaper too; ball bearings are kinda precision things and the processes that make things like gravel or nails probably cost less.

That said, if someone was really set on creating the opening scene of the movie Swordfish, they could make those ball bearings deadly if they got them going fast enough. A 3/8" ball bearing moving at a few hundred meters per second has enough energy to fuck up persons and property. I didn't pick those numbers completely at random -- 3/8" is about 9.5mm and common 9mm handgun rounds have velocities in the 300-400 m/s range.

Edit: I want to call attention to other replies to this comment pointing out that ball bearings can be good shrapnel for other reasons I'd not considered. Today I learned a thing.

That's assuming a rational customer ;)

The chance of your nail hitting pointy side first is very low. A ball bearing, being spherical, will always deliver maximum energy to the smallest point possible.
