Never forget that adjusting weight at the front of the arrow affects its spine.In these terms and conditions, “we” “us” and “our” refers to Evolusion Arrows. Instead, stick with the spine recommendations, and change the arrow’s inserts or points to adjust the arrow’s weight. 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.Īrchers who want to increase or cut arrow weight sometimes think changing spine is the only way to achieve their goal. Arrows with weaker spines generally weigh less than those with stiffer spines. Arrows that flex too much or not enough can fly erratically.Īrchers occasionally change their arrow spine incorrectly because they want to change their arrows’ overall weight. Moving away from those recommendations can hurt accuracy. Archers who don’t consider the effects of heavier points on spine might wonder why their arrow suddenly flies erratically.Īrchers selecting arrows should stick to the manufacturer’s spine recommendations. They can do that by using extra-heavy point inserts, increasing the weight of their points, or both. Point weight is a big factor, because many bowhunters try to boost their arrows’ penetrating power by adding weight to the front. That’s why Gold Tip recommends a 400 spine for a 27-inch arrow with a 100-grain point shot from a 60-pound bow, but also recommends a 340-spine arrow if its length and draw weight stay the same, but its point weighs 150 grains. Adding weight to the front of the arrow weakens its spine. Your arrow point’s weight also affects spine. Use the arrow length you intend to shoot when consulting the spine charts.
#Arrow spine chart full
Archers with a 27-inch draw length might shoot arrows anywhere from 26 to 29 inches long, depending on where your arrow rest is mounted, and how much arrow extends in front of the riser when you’re at full draw. Archers often confuse the two when picking arrows. Understand that the manufacturers’ charts refer to arrow length, not draw length. That’s why Gold Tip recommends the 400 spine for a 27-inch arrow shot at 60 pounds, as compared to the 340 at 30 inches. As you cut those arrows to fit your draw length, you make them stiffer. New, raw arrows measure around 33 inches when shipped by the manufacturer. But if you increase the arrow length to 30 inches for the 60-pound bow, the chart calls for a 340 spine. Increase the bow’s draw weight to 60 pounds and shoot that 27-inch arrow, and the chart again calls for a 400 spine. Take that same 50-pound bow, but increase the arrow length to 30 inches, and the chart calls for a 400 spine. Gold Tip’s spine chart recommends an arrow with a 500-spine rating, assuming the arrow carries a 100-grain point. Let’s say you have a 50-pound compound bow that shoots 27-inch Gold Tip arrows.
