# What spine should my arrows be?

## What spine should my arrows be?

Gold Tip’s spine chart recommends an arrow with a 500-spine rating, assuming the arrow carries a 100-grain point. Take that same 50-pound bow, but increase the arrow length to 30 inches, and the chart calls for a 400 spine.

What does 500 spine mean in arrows?

The spine rating of an arrow is simply a measurement of its stiffness. The same Easton arrow comes in a variety of stiffness: the lower the number, the stiffer the arrow. For example, a 330 arrow is stiffer than a 500 spine arrow.

What is stiffer 340 or 300 spine?

Registered. I put your specs into archers advantage on my iPad and the 300 spine was a tad stiff but the 340 was right on the edge of ok and weak. Maybe someone with OT2 can run your setup through it, it sometimes is more accurate than AA. But Usually better to be on the stiff side than weak side.

### How do I know if my arrow spine is correct?

Static spine is how much an arrow reacts when a 1.94 lb. weight is hung from the center of the arrow. 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.

What size arrow do I need?

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.

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.

#### How do you figure out what size arrows you need?

How long should my arrows be for a 28.5 draw?

But your arrows might not have to be 30 inches, either. Depending on what arrow rest you have and where you want the end of your arrow to sit on the shelf, you might be able to shoot an arrow that’s anywhere from 28.5 to 31 inches long. At its shortest, an arrow can be just long enough to sit on your rest at full draw.
