![]() Heavier bullet grains are resistant to wind and pack more of a punch, while lighter grain bullets are more accurate at long ranges. A grain is equal to 1/7000th of a pound (or 0.06 grams). What Is Bullet Grain?īullet grain is the weight of the projectile, measured in grains. Keep reading to see a breakdown of different bullet grains and a comprehensive chart showing the best grain for each caliber. In this article, I’ll explain the many aspects of ammunition that set one kind apart from another. They’ll usually be more than happy to help you select the best ammo for your situation and firearm. If you’re curious about recommended bullet grains for your particular firearm, it’s best to refer to the manufacturer or ask somebody at your local gun shop to point you in the right direction. The hunting recommendations are given as a range of effective bullet grains for various types of game, weather conditions, and ranges. When it comes to target shooting and self-defense, these recommendations are based on accuracy, recoil, and twist rate of typical firearms chambered for these calibers. Keep in mind, this isn’t a hard-and-fast set of rules but rather a guideline to help you select the best bullet grain for your firearm. Different projectile weights are suited to different calibers and applications, so selecting the correct bullet grain for a firearm is critical when buying ammunition.īelow is a chart for various calibers and applications, along with their respective recommended bullet grains and firearms. The grooves can vary in length, width and depth depending on the desired ballistic characteristics.Bullet grain is a unit of measurement representing weight and one of the most important considerations when selecting ammo.
