Kris: My drone is malfunctioning can you replace it under warranty?
Manufacturer: Hmm, that's no good, I'm sure we can. What happened?
Kris: I shot it a little bit with my 22-250
Manufacturer: Get...Out!

I can see a definite use for the drone for this purpose and with it at 6 feet away probably little risk of splatter...The lead basically goes to powder on steel anyway, especially at the speeds it's impacting at.
