What size carbon arrows do I need?
As a hunter, you probably know that traditional carbon arrows are measured differently than models made of other materials. Most carbon options are given a three-digit number that can tell the hunter how much a 28-inch spine arrow bends when a 2-pound force is pulling on its midpoint.
For example, a 400-carbon arrow will bend 0.400 inches, while a 300 model will bend 0.300 inches. To put it in simple terms, the lower the number, the more likely it is that the arrow will fit a bow that has a rather heavy draw weight.
When it comes to the length of the arrow, this all depends on your size. If you are a novice, you can go online to find numerous step-by-step guides that can help you determine what kind of arrow you have to use. If you have no idea how to measure this by yourself, you can also ask for help from a bow and arrow shop assistant.
