Question: What Happens If Arrow Spine Is Too Stiff?

What happens if your arrows are too lightly or too heavily spined for your bow?

Every arrow shaft has a degree of stiffness called spine, which is its resistance to bending.

If your arrows are too lightly or heavily spined for your bow, the “archer’s paradox” movements will be extreme, resulting in poor arrow flight and loss of accuracy..

How do I know what spine arrow to shoot?

The first variable you need to look at is draw weight. As draw weight increases, so should arrow rigidity (spine). Also, we strongly recommend that you use an arrow with at least 5 grains of weight per pound or draw weight (if you are shooting a 60 lb. bow, you should use and arrow of not less than 300 grains).

Does arrow spine really matter?

Stiff arrows group well at close distances, weak ones poorly. But, as the distances increase the stiff arrow which also varies a little in spine will not hit the same final flight path as easily as a weaker one. Therefore, the shot dispersion of a stiff arrow at long distance will be greater than a weak arrow is.

How do you weaken arrow spine?

Nock weight or rear weight – Adding weight to the rear of the arrow will increase or stiffen the arrow’s dynamic spine while removing weight from the rear of the arrow will decrease or weaken the arrow’s dynamic spine.

Do longer arrows fly better?

Longer arrows are generally more stable and slower, but don’t worry about that. You are better off shooting the correct arrow for your draw length. The spine also has to be correct for the arrow length and power rating of the bow.

Does draw weight affect accuracy?

In general, more draw weight will allow you to put a heavier arrow down range faster, making it less affected by wind and other environmental variables. The loose will also be more forgiving to release errors. As already noted, a faster arrow will also be more forgiving to errors is distance estimation for field.

How do I know if my arrow spine is too weak?

A lighter tip INCREASES an arrow’s spine (makes it act more stiff). If the arrow is too stiff it will favor the left side while if the arrow is a bit weak, it favors the right side.

Are 340 or 400 arrows heavier?

340 arrows are stronger/stiffer/harder in “spine” than 400 arrows because they bend less. 400 arrows are stronger than 500 arrows. … A weaker arrows is “softer”. Generally 600 arrows are for bows from 15–35 pounds in draw weight, 500 for 35–55 pounds, 400 for 55–75 pounds, and 340 for 75–95 pounds.

What does 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.

What does 500 spine mean in Arrows?

This arrow spine is measured in numbers. The lower the numbers, the thicker the arrow while the higher the number, the easier the shaft to bend. For example, an arrow with spine number 400 is stiffer than a 600 spine arrow.

What might you do to your bow if you use arrows that are too light weight?

Arrows that are too lightweight for your bow may cause you to essentially “dry fire” your bow.

How does arrow length affect spine?

The longer the arrow, the weaker the spine of the arrow becomes.

How long should my arrows be?

The standard way to measure arrow length is from the back of the point to the throat of the nock. Your draw length and arrow spine will influence your arrow length. If you’re a 28-inch draw length and want an arrow that ends at the front of the riser, your arrow length would be around 27 inches.

What happens if your arrows are too long?

If you shoot an excessively long arrow, not only will the excess shaft weight result in a heavier and slower flying arrow, but the added length may necessitate changing to an even heavier/stiffer arrow spine.

Does arrow spine affect accuracy?

Arrow spine comes back in play here. 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. … Optimizing the flight of your arrow is key to accuracy. While an arrow will necessarily twist and turn in flight, what you don’t want it to do is wobble.

What does 400 spine arrow mean?

“Spine” is the measurement of the arrow’s flex or bend. Arrow shafts are sorted by spine measurements, and manufacturers designate them with a number. … Some common numbers are 350, 400, 500 and 600, but they vary by manufacturer.

Do heavier arrows fly better?

Arrows come in three weight categories: light, midweight and heavy. Lighter arrows fly faster and can group more tightly, but they’re often harder to tune. Heavier arrows fly slower but resist wind better and penetrate deeper.
