I am shooting a 485 grain FMJ at 300 fps.
Loosing 20 fps won't have any effect what so ever on your animals. To be honest, the heavier arrow will make for a quieter bow upon release. So many times the heavier arrow will win out. Bow manufacturers however will never push this kind of thinking. Speed Is the **** these days.

Slightly over 500 grain arrow going in the neighborhood of 270 fps out of a BowTech Invasion CPX. Shot placement wins out everytime in the contest of light vs heavy but my experience has been a heavier arrow gives me an advantage in a number of areas if conditions or the shot aren't perfect.
No worries. I was more refferring to safety of the animal. At 262 the arrow will be in the air for quite a while, especially at 40 yards. So if it moves at all it could move out of the kill zone. Also, will the arrow have enough velocity to penetrate. I get momentum, but there is still a velocity portion to that, half the equation as a matter of fact.
