Question: What Happens If Your Arrows Are Too Lightly Or Heavily Spined For Your Bow?

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

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

How long should my arrows be for a 29 inch draw?

Static spine To calculate this, arrows must be 29” long and supported at two points 28” apart. The number of inches the arrow bends multiplied by 1,000 is the arrow’s spine. So, an arrow numbered 350, bends . 350” when the weight is applied.

What is a good FOC for a hunting arrow?

The best FOC for hunting arrows ranges between 10-15%. Larger FOC arrows will carry with them more power and penetrate better than those with less FOC.

What is the difference between a 300 and 400 arrow?

The word is SPINE, and there is . 1 inches difference in deflection between 300 and 400. Total arrow length and tip weight will determine what spine you need for which poundage you choose to shoot.

What is the disadvantage of an arrow that is too long for the bow?

In order to be tuned for the bow, the longer arrow must have a stiffer shaft, which is inherently heavier than a less stiff shaft of the same design. Then being longer than is needed also makes it heavier. Both of these criteria make the arrow slower and reduce its cast.

What does 400 mean on an 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 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.

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 is a good let off for a bow?

The decrease in holding weight is commonly referred to as the bow’s let-off. The percent of let-off is typically 65% to 85% depending on the bow, this gives you an idea of how much weight you will actually be holding at full draw. For example, a 70 lb. bow with 85% let-off means you will reach a peak weight of 70 lb.

How heavy should my arrow be?

Overall Arrow Weights I think a good average hunting arrow should fall in the 6 to 8 grains per pound of bow weight, with lighter bows maybe even closer to 9 to 10 grains per pound. A typical 60-lb. bow should be in the 360- to 480-grain range, a 70-lb. bow in the 420- to 560-grain range.

How long should my arrows be for a 28 draw?

around 27 inchesIf 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. However, your arrow length can be longer if you need to weaken the spine of your arrow.

What happens if your arrow spine is too stiff?

Too stiff an arrow usually just slows the bow down with a heavier arrow. Too weak a spine arrow usually yeilds a faster lighter arrow. But the light spine cause the arrow to shoot way off the mark as the range increases.

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.

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. Shooting the wrong arrow weight for a bow can damage equipment and harm the archer.

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.
