Front of Center balance point (FOC) is an abbreviation for Front of Center balance point. This measurement is derived from the relative weights of the components of the arrow, which include the shaft, insert, tip, fletching, and nock, among others. A well balanced arrow has dimensions ranging from 7 to 15% of its length. For additional information on determining arrow weight and FOC, please visit this page.
What does the abbreviation FOC mean in archery?
- F.O.C. is an abbreviation for “front-of-center” in the field of archery. The fraction of the arrow’s total weight that is positioned in the front half of the arrow is referred to as the FOC.
What is the ideal FOC for an arrow?
Recommended Practices for the FOC In general, FOC recommendations for broadhead-tipped arrows range from 12 to 15 percent, whereas field points range from 8 to 11 percent, according on the manufacturer. Hunting bowhunters who shoot arrows shorter than 26 inches in length and those who shoot with their fingers should lean more toward the 15% to 18% percent range.
What is a good hunting FOC?
The ideal FOC for hunting arrows is between 10-15 percent, which is considered optimal. Arrows with a greater FOC will carry more power and penetrate more effectively than arrows with a lower FOC value.
What is considered a high FOC?
According to the industry, 8-12 percent FOC is usual. A high FOC arrow has a starting point of roughly 15 percent and can go as high as 30 percent.
How much FOC do I need for traditional archery?
Up to 12 percent is considered regular FoC; 13 percent to 19 percent is considered high FoC; and 20 percent and above is considered severe FoC, which is exactly what we want in a large game arrow system. For the most part, as long as arrow flight stays faultless, the higher the field of combat (FoC) and hence the better the penetrating capability.
Do heavier arrows fly better?
Arrows with a lot of weight penetrate better. The first reason it’s critical to select the greatest hunting arrow is that once an arrow departs the string, it no longer has the ability to push itself forward. According to Newton’s Second Law of Motion, the quicker arrow has a bigger influence on the deceleration of the faster arrow, which causes it to decline faster than the slower arrow.
How much FOC do I need for elk?
In addition to penetration, the front of center (FOC) of an arrow is vital, and I try for a FOC of at least 12 to 13 percent or higher. It is possible to get away with a lighter, flatter arrow if your draw weight and arrow speed are outstanding (far above 300 fps), but I would not recommend going any lighter than 400 grains under any circumstances.
How heavy of an arrow should I shoot?
The front of center (FOC) of an arrow is also critical for penetration, and I aim for a FOC of 12 to 13 percent or higher. It is possible to get away with a lighter, flatter arrow if your draw weight and arrow speed are extraordinary (far above 300 fps), but I would not recommend going any lighter than 400 grains under any conditions.
How do you find the FOC of an arrow?
When calculating FOC percent, the usual formula is FOC percent = 100 x (AL/2)/L, where L is the right arrow length, and A is the distance from the nock groove to the final arrow balancing position, which includes the arrow point/insert weight, nock, and fletching, respectively.
How heavy should a whitetail arrow be?
500 points is a significant improvement above 437 points. If you’re on the fence about arrow weight, here is the place to start. They should consider the bone density of adult whitetail deer and the size of their antlers. A sharp fixed blade with a high foc of over 20% and a combined weight of 550 is starting to get close to being perfect for pass throughs; anything less than that is less than ideal for this application.
How heavy should arrow be for elk?
420 grains is the minimum final arrow weight that I suggest for hunters drawing 60-70 pounds while hunting elk with a bow. Despite the fact that bows are getting more efficient and that lower-poundage bows are capable of bringing down huge game, higher-poundage bows will undoubtedly aid you in taking down large wildlife.
What happens if you shoot an Underspined arrow?
Shooting an arrow that is not stiff enough, or a collection of arrows that are of different stiffnesses, can lead you to be less precise in your shooting. An arrow with a weak spine will veer to the right, whereas an arrow with a stiff spine would deviate slightly to the left.
How does arrow length affect FOC?
The FOC should be increased in proportion to the length of the arrow shot. Arrows that are shorter in length are fundamentally less stable in flight. Fletching is aided in overcoming this by the longer back lever. A finger release also contributes to arrow instability, particularly during the first flight phase.
What is a good FOC for crossbow bolts?
An aircraft with a high factor of safety will fly with good steadiness, but it will lose its direction more quickly and nosedive. As opposed to this, while a crossbow bolt with a low factor of caution will maintain its trajectory better, the bolt will also fly more erratically. For hunting conditions, crossbow bolts with 10-15 percent F.O.C. are recommended for hunting setups and best accuracy, according to the manufacturer.
What is the weight of an arrow?
A light arrow has a completed GPP of 5 to 6.5 grains for every pound of draw weight, depending on the weight of the arrow. A midweight arrow weighs between 6.5 and 8 grains, depending on its length. Heavy arrows have a weight of more than 8 grains. When shooting with a recurve, barebow, or compound bow, this knowledge can be very useful.
