    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.

    Hey Indy
    I don't understand part of the question.
    Why would it not be safe?

    Bear in mind that I am new to this sport. :bash:

    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.

    262 fps vs 300 fps at 40 yards will be a second difference in flight time. Also a 400+ grain arrow at 262 will put the smack down on a deer at 40 yards and it would have a straighter flight line than the lighter arrow would . If you ask me the heavier arrow would be a safer arrow to shoot at 40 yards appose to the lighter arrow if hitting the kill zone is your worry. I was also one of those to choose speed and lighter arrow over a heavier arrow. I just recently made the switch to a Easton axis 340's over the 400's I was using. I went from a 345 grain arrow at 307 fps to a 386 grain arrow at 293 fps. I get an avg of 3" more penetration with the 400's and not even a blink of an eye difference in speed.
