![]() After all, shooting sub-MOA groups isn’t the end all be all of a fun day at the range. However, if you just want to throw some lead downrange, don’t be hesitant to grab a couple of boxes of whatever is cheapest. Sure, if you are getting ready for a big competition or planning to do some hunting, you’ll want to make sure you get the best loads for your AR-15 regardless of price. The good news is that the vast majority of factory ammunition is of good quality. Sometimes ammo prices are going to dictate which brand or type that you buy. Shooting sports can sometimes be expensive endeavors to participate in. For example, a 1:7 twist rate is faster than a 1:9 twist rate. The general rule of thumb is “the heavier the bullet, the faster the twist rate.” A faster twist rate is one with a smaller number on the right side of the colon. Instead, it is most important to just know the ideal bullet weight for your specific barrel’s twist rate. Understanding the physics behind this isn’t important for those of you buying factory loads of ammo. This has to do with how well a bullet is stabilized due to variables such as total grains of bullet weight, spin rate, and barrel length. Certain bullet weights perform best with specific twist rates. So what does all of this have to do with finding the best ammo for your AR-15? A twist rate of 1:12 is less common but is still out there. The most common twist rates are 1:7, 1:8, and 1:9. For example, a bullet fired from a barrel with a twist rate of 1:9 will spin one revolution every 9 inches in the barrel. The twist rate of a barrel tells you how many inches it takes the barrel to spin the bullet one revolution. The twist rate will be stamped or engraved somewhere on the barrel. If you aren’t sure of your twist rate, just check your barrel. FMJ ammo is great for plinking and target range use.īefore starting your ammo selection process, you should always keep the twist rate of your barrel in mind. This is accomplished without leaving significant amounts of metal behind in the bore. This so-called “jacket” allows for increased muzzle velocities when compared to bare lead. Often used in the most affordable types of ammunition, full metal jacket bullets feature a lead core encased in a shell of harder metal such as gilding metal. ![]() ![]() This is especially good to have in home and personal defense situations which can occur near innocent bystanders. The expansion of hollow points helps to reduce over-penetration that could lead to unwanted damage beyond the target. ![]() Home and personal defense purposes generally call for the use of hollow point bullets. With a great ballistic coefficient and less drag than traditional hollow points, hunters can be incredibly accurate and precise with their shot placement on coyotes, groundhogs, and other varmints, and small game. They expand upon impact in a more controlled way which reduces damage to fur and meat. Soft point bullets are most commonly used for hunting purposes. There are more types than those three, but having a better understanding of these three will help you out a lot. Three of the most common types of bullets are soft point, hollow point, and full metal jacket. Check out the list below to arm yourself with the knowledge to make an informed choice. There are a few important factors to think about and consider when choosing AR-15 ammo. Factors to Consider Before Buying AR-15 Ammo ![]()
