Shotgun slugs are large metal projectiles that fit into a shotgun shell. They’re used for hunting larger animals in comparison to birdshot/buckshot where it’s a bunch of tiny pellets that spread out.
This is extremely sad... People deal with grief differently, so I don't think it's fair to say that fathers losing their sons is the worst. All the scenarios are all horrible, whether it's a parent losing their child, a husband losing his wife, a child losing their parent...
( don't get any worried ideas I speak of a time in my past)
