5) NockĪ standard plastic nock will weigh somewhere around 5-10 grains. The standard three-fletch configuration with plastic hunting vanes will add somewhere between 15-30 grains of total weight, depending on the vane used. (All of these elements are calculated in the arrow weight calculator). The most common broadhead weights are either 100- or 125-grains, though much heavier heads are available. Some inserts are customizable, that is, they can be easily shortened to drop their weight down a bit so you achieve the exact finished arrow weight you’re looking for. These inserts typically weigh between 50 and 75 grains, though some are heavier.
Many arrow makers offer metal inserts – usually made of brass or aluminum - that can be inserted into the throat of the shaft to add overall weight and increase the weight/forward balance of the shaft. Regardless of weight, you have to choose the right arrow spine to ensure laser beam arrow flight. It’s important to remember that arrow weight is not arrow spine, which determines how much your shaft will flex when it leaves your bow. All major arrow manufacturers list how much each of their different raw arrow shafts weighs in grains per inch.Ī so-called light arrow might weigh 8 grains/inch, while heavier shafts can weigh north of 11 grains/inch. As a point of reference, 437.5 grains equals one ounce – or one grain weighs just 0.00228571 oz. These factors are: 1) Grains Per Inch (GPI)Īrrow, and arrow point, weight are measured in grains. When I build a hunting arrow, I use an arrow weight calculator to estimate how much my finished arrow weight will be before I get started, which lets me create the perfect arrow, with weight in mind, for a particular situation. Many elements go into determining an arrow shaft’s final overall weight. Use an Arrow Weight Calculator to Estimate Heavier shafts, and overall arrow weight, are selected when larger game is the quarry.
