Depending on the manufacturer, a lighted nock will weigh grains more than a standard nock. What constitutes light, medium, and heavy shafts? Using my own inch draw length as an example, a light hunting shaft would weigh approximately grains. A medium-weight shaft would weigh in at grains, while a heavy shaft would weigh grains or more. Bowhunters may choose a lighter shaft for increased initial raw arrow speed and a flatter trajectory, or when hunting thin-skinned game like pronghorn, and opt for a heavier shaft for larger, tougher game like elk and bears.
To increase kinetic energy, an arrow should be set up with more overall mass than the average arrow. This can be achieved multiple ways. First, choose an arrow shaft with a higher weight per inch GPI.
Easton Full Metal Jackets are a great option for archers wanting to achieve higher arrow mass while still being a smaller diameter shaft. Easton offers the FMJ arrows in 4mm , 5mm , and 6mm. Smaller shaft diameter shafts have multiple benefits as well including less wind effects and less friction when entering the target.
Pre-preg is the term for carbon fiber that has been infused with resin and varies depending on the resin type and carbon strand count. Victory also infuses different materials into the carbon layers of its shafts for strength and durability. Its VAP-SS and Xtorsion arrow, for example, feature stainless steel mesh infused with the carbon layers to make a heavier, harder hitting arrow. Click here to learn more. For reference, light arrows weigh about grains, a typical arrow weighs to grains, and a heavy arrow weighs over grains.
Archers who shoot a recurve or longbow normally use arrows weighing grains or more. Your arrow weight has to be calculated against your draw weight for the best performance.

You are dealing with physics, aerodynamics and energy transfers. Your form, mental state and decision-making all factors into the equation of a perfect shot. Bowhunting and archery terms can get technical. Arrow spine is one of those terms that can seem technical on the surface, but can be easily explained.
Here is what arrow spine means and how it affects the flight of your hunting arrow. 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 arrow is stiffer than a spine arrow. There are two kinds of spine stick with us, we promise not to get too technical.
The number of inches the arrow deflects or bends X due to the weight is the spine size or measurement of an arrow.
