While I won't doubt that everyone here can shoot tiny groups at 20 yards, a lot of people who think they're good shots can't hit an IPSC target at 20 yards anywhere on the paper. Depending on the rate at which the shots are fired and the level of stress, a 15 inch group at 20 yards isn't that bad (in my opinion).
Capping off a round into the ground next to your foot is not acceptable, however. Anyone who does that won't have any more concern for someone else's foot (or other part of their body) either, which is what makes them really, really dangerous.
On the bright side, at least he was out practicing. Sounds like he definitely needs some professional instruction, though. That assumes, of course, that he's coachable and willing to learn and change his potentially deadly negligent habit to habits that encourage significantly safer outcomes.
