What does 400 spine mean on an arrow?
This arrow spine is measured in numbers. The lower the numbers, the thicker the arrow while the higher the number, the easier the shaft to bend. For example, an arrow with spine number 400 is stiffer than a 600 spine arrow.
How heavy is a 400 spine arrow?
The 400 shaft weighs 8.5 grains per inch.
What arrow spine should I shoot?
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).
Are 340 or 400 arrows heavier?
New, raw arrows measure around 33 inches when shipped by the manufacturer. As you cut those arrows to fit your draw length, you make them stiffer. 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.
Does arrow spine really matter?
Having the proper arrow spine is key to optimizing the grouping of your arrows and for the best possible accuracy. Shooting an arrow that is not stiff enough, or a group of arrows that vary in stiffness, will cause you to be less accurate.
Are longer arrows more accurate?
If you’re consistent on draw length, arrow length matters little except for precision shooting. But, arrow length affects dynamic spine, so if your arrows are the same spine, but different lengths then they aren’t actually the same spine. As long as they’re all the same, not really.
What does 45 60 Mean on an arrow?
it means 45-60 lb bow.. If your draw is longer than normal and you shoot 60 lb you usually need a lttle more that what the arrow is rated for..
What happens if your arrows are too lightly or too heavily spined for your bow?
Every arrow shaft has a degree of stiffness called spine, which is its resistance to bending. … 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.
How do I choose arrow weight?
If you want to target practice, you want the arrow to weigh in total (shaft, vanes, insert, nock and field point combined) around 5 to 6 grain per pound of draw weight. So if your bow has 60 lbs. of draw, you want to use arrows that weigh in total between 300 and 360 grain.
What happens if my arrow is too long?
If you shoot an excessively long arrow, not only will the excess shaft weight result in a heavier and slower flying arrow, but the added length may necessitate changing to an even heavier/stiffer arrow spine.
What does 300 mean on an arrow?
100, 200, 300, and 400. So the larger the number, the heavier and stiffer the arrow.
What might you do to your bow if you use arrows that are too lightweight?
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.)
