Is the spine of an arrow the weight?
Is the spine of an arrow the weight?
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. The number of inches the arrow deflects or bends X 1000 due to the weight is the spine size or measurement of an arrow. So, a 500 arrow bends .
Does arrow spine affect weight?
Adding weight to the front of the arrow weakens its spine. 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.
How much should my hunting arrows weigh?
For reference, light arrows weigh about 350 grains, a typical arrow weighs 420 to 500 grains, and a heavy arrow weighs over 600 grains. Bentcik said few Americans use arrows weighing 700 grains or more unless they’re shooting traditional equipment.
How heavy is a 400 spine arrow?
40-60 lbs.
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 mean on an arrow?
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.
How much does a 400 grain arrow weight?
So the 400 grain arrow weights 0.914 ounces.
What is the best rating for arrow spine?
The gold standard for rating arrow spine has always been Easton’s fitment charts. Before carbon arrows hit their stride in the 1990’s, practically every archer in the world had at one time studied the little blocks on the Easton chart, trying to decide if the 2219’s, 2413’s, or 2315’s would be better (remember?).
What is the minimum arrow weight for archery?
Arrow weight (in grains) must be at least 5X the bow’s draw weight. So a 60# bow should shoot no lighter than a 300 (5 x 60) grain arrow. Simple enough. Another authority in the archery industry, the Archery Trade Association (formerly the AMO), also publishes an arrow weight recommendation chart called the AMO Minimum Arrow Weight Chart.
Did the Gold Tip Arrows really have a 5575 spine?
But it didn’t always work out that way. The Gold Tip arrows had spine deflections of .500″ (3555), .400″ (5575), and .340″ (7595) respectively. So for example, a 53# bow shooting a 30″ arrow actually required the 5575 spine (per the Easton gold standards anyway) instead of the 3555 that Gold Tip’s sizing convention might suggest.
