Doegirl, I hate to see you receive so much misinformation, so I'm going to explain why the heavier, higher FOC does not work the way others would have you believe.

First, all arrows, whether 300 gr, 600 gr or 1000 gr, drop at the exact same rate. Gravity determines this. The rate is 32'/sec/sec. The only thing that affects this drop rate is air resistance. The amount of resistance is dependent on things like surface area and surface friction. The difference in these for different arrow designs is negligible at typical hunting distances. Therefore, the 32'/sec/sec works just fine for figuring drop. The other variables are the speed of the arrow and the distance of the target. All together, these give you the total drop - nothing else. It doesn't matter one bit if the weight is on the tip or in the middle, a 400 grain arrow will drop the same amount at a given target at a given speed. I can say this with confidence because of two things. One is the laws of physics and two, I've tested this in the field. "Nose dropping" because of heavy tips is a myth perpetuated by those who don't know better.

If you shoot a 3 pin sight and set them at 15, 20 and 25 yards, you will hit exactly where you should as long as you know the yardage before you shoot and don't extend your range much past 25 yards. Penetration will be better for two reasons. First, heavier arrows contain more momentum and retain more energy downrange and two, extreme FOC arrows are proven to penetrate animals better. It's especially important for those with shorter draw lengths and lower draw weights to use the heavier, higher FOC arrows, because they give you advantages that your draw weight and draw length take away.
