FAQs

Question: Is FOC (front of center balance) really important?  
Answer: FOC is important, but really begins to take effect at longer shot distances (40 yards plus).  For a hunting arrow chose an FOC in the range of 8-12%.  Some target applications will require more than that, but there are not any written rules as to how much is best.  Trial and error is the best method to be employed here and the use of Gold Tip’s weight system makes tinkering with FOC a very simple prospect.  Check out the weight system Link
 
Question: How can I measure my arrow’s FOC?  
Answer: First, find and mark the balance point of the arrow by balancing your arrow on a narrow surface (your finger will work fine).  Secondly, find the center of your arrow by dividing the total length by two (2) and marking it on the arrow.  Now measure the distance between the center and balance point and divide that number by the total arrow length.  Lastly, multiply that number by 100 to get your FOC percentage.

Question: How do I calculate Kinetic Energy?
Answer: Kinetic Energy= Velocity Squared multiplied by Mass (arrow weight in grains) divided by 450,240 
 
Question: How does the straightness tolerance of an arrow affect accuracy?
Answer: Straightness can have a significant effect on the accuracy of an arrow.  Although the difference between a .006” and a .001” straightness arrow won’t be night and day you will definitely notice accuracy advantages with a straighter arrow, particularly if you are shooting broadheads. 
 
Question: What are the advantages or disadvantages of a light arrow vs. a heavy arrow for hunting?
Answer: This is a question that has been asked and answered many different times and ways over the years and there is not a clear cut answer.  However, it is common to measure an arrows penetrating power in terms of Kinetic Energy (KE).  With this method being employed you will find that the KE of an arrow is dictated more by the bow than the arrow and that a heavy arrow and a light arrow fired from the same bow will produce almost exactly the same amount of KE.   That being the case, many hunters today are opting for the lighter arrow in order to increase margin for error in yardage estimation, get tighter pin gaps for in-between shot distances, and reduce time to target of the arrow.  Check out Gold Tip’s new lineup of light weight Velocity hunting arrows Link
 
Question: What size fletching should I use?
Answer: Trial and error for your particular setup is the best answer here, but a good rule of thumb is to use the smallest amount of fletching possible that will still provide good accuracy and stability.   Longer fletching is heavier, creates drag (which slows your arrow more quickly), is more susceptible to contacting your arrow rest or cables, and is more susceptible to windy conditions. However, none of these factors are worth worrying about if you cannot get adequate stability, so you may still want to opt for that 4” vane.
