Understanding Bullet Size

Before we dive into the bullet sizes, let's clarify what we mean by "bullet size." The size of a bullet is typically referred to in caliber, which is a measure of the diameter of the bullet in inches or millimeters. Different calibers are designed for different types of firearms and shooting situations, and they also affect factors like recoil, range, and stopping power.

The Smallest Bullet Sizes

1. .22 LR (Long Rifle)

   • Diameter: .223 inches (5.6mm)
   • Common Uses: This caliber is popular for training, plinking (recreational shooting), and small game hunting due to its low recoil and cost-effective ammunition.

2. .17 HMR (Hornady Magnum Rimfire)

   • Diameter: .172 inches (4.4mm)
   • Common Uses: Known for its high velocity and flat trajectory, the .17 HMR is favored for varmint hunting and offers excellent accuracy at longer ranges compared to the .22 LR.
