What spine carbon arrows do I need?

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).

Can arrow spine be 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 spine is a carbon Express 4560?

Size: 4560 (8.97gpi & . 400 spine)

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

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. (It’s better to err on the stiff, or too heavily spined, side.) Arrow manufacturers publish selection charts that match bow weights to proper arrow spine.

What spine arrow should I shoot with a 70 lb bow?

You can shoot every spine at 70# if your arrow weight at least 350 grains. It will be safe, but if the spine is not the correct, it will not fly as it should…

Why do my arrows wobble in flight?

Mechanical release aids remove the left-right waggle, but the pressure comes in the vertical plane (from the string), and the rest only contacts the arrow from the bottom – meaning the arrow wobbles up and down.

What is the difference between 250 and 350 arrows?

The 250 spines are for lighter bows (30 pounds to 75 pounds, depending on the length of your arrows); the 350 spines are for midrange bows (58 pounds to 93 pounds, depending on the length of your arrows); and the 450 are for heavy bows (64 pounds and up to 93 pounds, depending on the length of your arrows).

What is a 340 spine arrow?

The most common spine sizes range from 260 to 500. 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.
