New gun owners tend to focus on their newly acquired piece of hardware, which is designed for their personal safety, for recreational shooting—or both. It's an awesome moment when they realize they've joined millions of other law-abiding Americans in exercising their Second Amendment rights. As such, their first goal is usually to make sure they learn to shoot safely and properly—all noble endeavors. Beyond the basics of pistol operation, however, is the equally important topic of ammunition. If you are a new gun owner, or are among those who take what you put down your barrel for granted, this new video in the second season of Smith & Wesson GUNSMARTS series is for you.

In “How Does Ammo Work?” Smith & Wesson pro-shooter Julie Golob offers a crash course in ammo lingo—for instance, what exactly is a bullet versus a cartridge? How does a bullet make its way out of the barrel? The type, size and weight of the ammunition also plays a huge role in how the gun feels when you pull the trigger—otherwise known as recoil. And of course, understanding the difference between center-fire and rimfire ammo is critical. There are many other things to know, too. So if you’re just getting started and feel the need for an ammo primer, check out this latest video in the new GUNSMARTS Series 2.
