arrow weight

[Arrowcraft]

I was under the impression that one should shoot arrows that weigh approx. 9 to 10 gr. per pound of bow weight. That being said a 52# bow should be shooting an arrow that weighs approx. 520 gr. now add a broadhead and you are at a min of 620 and up ? I have also been following how many guys shoot heavy heads and even add weight forward. I am referring to woodies in this case scenario, now you are getting really heavy ?Any insight to this would be appreciated thanks

That rule of thumb is for total arrow weight -- including the point.  For the basic 10 grains per pound, it doesn't matter if you are using the old standard of ABOUT 14% FOC or a EFOC produced by a heavy point.  It is still TOTAL arrow weight including the point.

The reason people are advocating more weight up front, or EFOC as they call it, is to achieve greater penetration in animals.  But if you take a step back from that, shooting a well tuned arrow is fundamental, because losing energy through arrow wobble will cost you everything you gain through EFOC, and then some.  For example, if you take a well tuned arrow with a 150 grain broadhead on it, and just substitute a 200 grain broadhead without changing anything else, you will have gained EFOC but lost overall efficiency, and will be worse off than if you had just stuck with the 150 grain broadhead.  OTOH, if you change to a stiffer shaft to compensate for the heavier point weight so the new arrow is in tune, then you will have gained all the benefits of EFOC for hunting.

None of this has any relevance to target shooting, BTW, other than as preparation for hunting.  An arrow optimized for 3D or target shooting will be much lighter overall to gain a flatter trajectory and have an FOC of 10-15%, far lower than EFOC ranges.
