The .22 caliber bullet, also known as the .22 caliber rimfire or simply the .22, is a popular choice among shooters for its versatility and affordability. Whether you're a hunter, target shooter, or just enjoying some recreational shooting, understanding the dimensions of .22 caliber bullets is essential. In this comprehensive guide, we will delve into the world of .22 caliber bullets, exploring their specifications, types, and applications.
Understanding .22 Caliber Bullet Dimensions

The .22 caliber bullet, often referred to as the .22 long rifle (LR) or .22 LR, is a rimfire cartridge that has gained immense popularity due to its accuracy, low recoil, and low cost. It is widely used for various shooting disciplines, making it a staple in the shooting community.
Let's break down the key dimensions of the .22 caliber bullet:
- Caliber: The caliber of a bullet refers to its diameter. The .22 caliber bullet has a caliber of approximately 0.224 inches (5.69mm) for the bullet itself, while the case has a diameter of 0.228 inches (5.80mm). This precise sizing ensures a snug fit within the firearm's barrel, promoting accuracy and stability during firing.
- Length: The overall length of a .22 caliber bullet varies depending on the type and manufacturer. On average, the overall length ranges from 0.8 inches (20.6mm) to 1.2 inches (30.5mm). This variation accommodates different firearm designs and shooting purposes.
- Case Length: The case length of a .22 caliber bullet is typically around 0.6 inches (15.6mm). This measurement includes the rim, which is an essential component for rimfire cartridges as it provides the ignition source when struck by the firing pin.
- Weight: .22 caliber bullets come in various weights, ranging from lightweight to heavy. The weight can significantly impact the bullet's performance, including its velocity, accuracy, and trajectory. Common bullet weights for the .22 caliber range from 29 grains to 60 grains.
Types of .22 Caliber Bullets

The .22 caliber bullet family encompasses a wide range of bullet types, each designed for specific purposes. Here are some of the most common types:
- Lead Round Nose (LRN): This is the most basic and widely available type of .22 caliber bullet. It features a round nose and a lead core, making it an affordable choice for target practice and plinking. LRN bullets are known for their accuracy and low recoil.
- Lead Round Nose Hollow Point (LRNH): By adding a hollow point to the lead round nose design, the LRNH bullet enhances its expansion capabilities. This type is commonly used for hunting small game, as the hollow point increases the bullet's effectiveness in producing clean kills.
- Lead Round Nose Flat Point (LRNF): The flat point design of this bullet reduces air resistance, making it ideal for long-range shooting. It offers excellent accuracy and is often used for competitive shooting disciplines such as precision rifle shooting.
- Full Metal Jacket (FMJ): FMJ bullets are characterized by their fully enclosed metal jacket, which surrounds the lead core. This design minimizes lead exposure and makes the bullet more stable during flight. FMJ bullets are commonly used for training and practice, as well as for target shooting.
- Rimfire High Velocity (RHV): RHV bullets are designed to achieve higher velocities, making them suitable for long-range shooting and small game hunting. They typically have a higher grain weight and a longer case length, resulting in increased muzzle velocity.
Applications of .22 Caliber Bullets

The versatility of .22 caliber bullets makes them suitable for a wide range of shooting activities. Here are some common applications:
- Target Shooting: Due to their accuracy and low recoil, .22 caliber bullets are an excellent choice for target shooting. Whether it's competing in precision rifle matches or practicing at the range, the .22 LR offers a cost-effective and reliable option.
- Plinking: Plinking, a recreational shooting activity, often involves shooting at various targets, such as tin cans or paper plates. The .22 caliber bullet's low cost and minimal noise make it perfect for plinking, allowing shooters to enjoy a fun and affordable shooting experience.
- Small Game Hunting: The .22 caliber bullet is widely used for hunting small game, including squirrels, rabbits, and birds. Its accuracy and controlled expansion make it an effective choice for clean and humane kills.
- Training and Practice: For new shooters or those looking to improve their skills, the .22 caliber bullet is an ideal training tool. Its low recoil and affordable ammunition make it an excellent choice for building confidence and developing shooting techniques.
- Competitive Shooting: Competitive shooting disciplines, such as biathlon and smallbore rifle shooting, often utilize the .22 caliber bullet. Its accuracy and precision make it a popular choice for competitions, where every shot counts.
