Correct arrow length is measured from the bottom, inside of the nock groove (deepest point where the string goes into the nock) to the cut end of the shaft, not including the point or point insert .
What does a 340 arrow mean?
As with combination arrows, a smaller number means the arrow has a stiffer spine. Therefore, a value of 340 indicates a stiffer and heavier spine while a value of 500 indicates the lightest and most flexible spine.
How are archery arrows measured?
What size arrows for a 30 inch draw?
| Bow Arrow length | Draw weight lb. 25′′ 30′′ | 15-20 700 600 | 20-25 700 500 | 25-30 700 500 |

What length arrow do I need for 27 inch draw?
The arrow must be 29′′ in length and supported by two points, which are 28′′ apart.
Where are arrows measured?
HOW DO I MEASURE CORRECT ARROW LENGTH? Correct arrow length is measured from the bottom, inside of the nock groove (deepest point where the string goes into the nock) to the cut end of the shaft, not including the point or point insert .
What is a 500 spine arrow?
The number of inches the arrow deflects or bends X 1000 due to the weight is the spine size or measurement of an arrow. So, a 500 arrow bends . 5-inches when the weight is applied . Then there is dynamic spine, which describes the way an arrow reacts from the stored energy of a bow as it is shot.
What is a 400 arrow?
The numbers refer to the spine of the arrow. The different spines refer to the stiffness, a 400 spine arrow is generally for bows 40-60 lbs . 350 spine is for bows roughly 55 – 75 lbs, and a 500 spine arrow is for bows roughly 30 – 50 lbs.
What happens if arrow spine is too stiff?
If the arrow’s spine is too weak or too stiff, the arrow will not correct itself as soon as it should while in flight . If that arrow is weak and continues to flex (has a low spine rating), it’s going to veer off target. Likewise, if the arrow is unforgivingly stiff, it also won’t follow the path the archer intends.
What is the average length of an arrow?
Arrow sizes vary greatly across cultures, ranging from eighteen inches to six feet (45 cm to 150 cm). However, most modern arrows are 75 cm (30 in) to 96 cm (38 in) in length.
Are shorter arrows more accurate?
So you know that the shorter and stiffer the arrow the better for speed and accuracy , the tradeoff against this is safety.
Is arrow length the same as draw length?
The main difference between draw length and arrow length is the way these two are measured. Draw length Is the distance from the deepest grip of the throat to the nock point plus 1.75′′ at full draw. On the other hand, arrow length is the distance of the arrow shaft .
How long should my arrows be for a 29 inch draw?
it depends on the arrows you choose, you need at least 1/4′′ of arrow overhang on the rest . so you can probably shoot an arrow that’s about 28 1/4 for rests that are set up normally. and go all the way up to full length 36′′ arrows for indoor. i would suggest 1′′ of overhang on your rest.
What happens if your arrows are too long?
It can’t hurt if it’s too long if it’s shoots well for you. Too long and you have to have more spine which adds arrow weight, more fletching, and heavier tips for proper FOC (arrow balance) .
What length should arrows be cut?
A good rule of thumb is to cut it no shorter than the middle of the riser . At full draw, your arrow end would sit right in the middle of the shelf. The best way to determine how long you want your arrows to be is to nock a full-length, uncut arrow and draw it back.
What length arrows for 27.5 draw?
It really depends on you, some like them flush with the front of the riser, some like them just past the rest and as short as possible. I have a 27.5-28′′ draw and my arrows are typically 27.75′′ . I wouldn’t want that long of an arrow personally. If you decide you want a heavier tip you will want a stiffer arrow.
How far should your arrow be past your rest?
The best safety practice is to make sure your arrows sit at least 1′′ beyond your arrow rest when the bow is at full draw. A little bit of extra arrow length gives the arrows an important margin of safety. A little too long is okay. A little too short is not.
How many grains is a 500 spine arrow?
Arrows with weaker spines generally weigh less than those with stiffer spines. The Gold Tip Hunter XT in a 500 spine, for example, weighs 7.3 grains per inch , while the same arrow model in a 300 spine weighs 9.3 grains per inch.
How do you weigh arrows?
Divide the arrow’s length (distance from the bottom of the nock groove to the shaft’s end) by 2. Find the balance point. This is where the arrow balances perfectly. Mark the point, and measure from there to the nock’s throat.
What is the end of an arrow called?
Arrowhead : The point of the arrow. Many different kinds of arrow points are available, each with a different purpose and advantage. Nock: A slotted plastic tip located on the rear end of the arrow that snaps onto the string and holds the arrow in position.
How do you cut arrows?
Can you shoot a 400 spine arrow 70 pound bow?
Most arrow charts will recommend a 400 (with 100gr tip) and most comp programs will say 350 (with a 100grain tip). If you shoot an 85gr tip, you will likely see better results with a 400.
What grain of arrow should I shoot?
If you want to target practice, you want the arrow to weigh in total (shaft, vanes, insert, nock and field point combined) around 5 to 6 grain per pound of draw weight . So if your bow has 60 lbs. of draw, you want to use arrows that weigh in total between 300 and 360 grain.
Do heavier arrows fly better?
So, as you can see, while a lighter, faster arrow shot from a modern compound bow produces significantly higher kinetic energy than a traditional bow shooting a much heavier arrow, the heavier arrow is actually carrying more momentum and, with all else equal, would be more likely to pass through the animal.
Do arrows spin in flight?
Do arrows really spin while in flight? Absolutely! The arrow’s fletchings – feathers, plastic vanes or curled plastic wings – steer the arrow in flight, helping it catch the air and spin for a straight flight pattern.
What spine arrow should I shoot with a 70 lb bow?
With a 26.5-27′′ arrow out of your Bear, a 400 spine arrow would work just fine. Arrow length plays as big a factor as does draw weight.
