The mass of an object doesn't effect the speed at which it falls (in a vacuum), so it's only drag and position of the balance point that makes it fall point first. If the centre of mass is only just front of centre and you put the fletchings just behind the point it would fall nock first >:D  ;)
I say one arrow shot a few times that flew completely wild, veering sideways, nosediving the suddenly climbing again before eventually settling to a more normal flight on a path about 46 degrees right of the line of aim.
My guess was it's centre of mass was too close to the geometric centre (about 1/8").
It wasn't an arrow that I'd made.
