A little off subject, but I hope that shooting handguns at long range is not the definition of insanity.
As for practical applications........I have a hard time imagining the need (for me)to ever shoot at anything less than fifty yards away.
No, insanity is BFR. He's kra-kra. I don't think long range handgunning is insane, it's just not something I'd enjoy.
I have a hard time imagining the need for me to shoot something with a handgun beyond 50 yards. Neither is wrong, just different strokes.
