Hmmm.
Sounds like a “hold mah beer - hey watch this” moment ....... In the boonies we carried capture poles for bad doggies and sniks etc etc ...... I think the post above about the LEO in the attic shooting at vs up towards the snake is the plausible scenario that killed the kid.
Mythbusters did a show on falling bullets , projectiles fired from handguns and pretty much proved a hit from a round dropping from the sky , fired from the ground , hasn’t enough force to kill or seriously injure. I’d suggest from here on the couch with information provided this was a horizontal high velocity hit vs vertical artillery impact.
Stay safe !
