Actually I think it's an advantage to load hot if the shooter & the bullet are on the same page. It's when the load is too much for the shooter (recoil) or the load is too hot for the bullet that things get out of whack.
Faster, flatter & hitting harder makes sense if the shooter is up to the task & builds correct loads, I've never stated other wise. I do question some one building loads they can't handle or using the wrong bullet at high speed, that's just asking for trouble.
Good loads & good shooting kills a lot of game with a six gun.
