Centerfire Ammo

What is Centerfire Ammo?

Centerfire ammo is a type of cartridge where the primer is located in the center of the casing base. When struck by the firing pin, the primer ignites the gunpowder, propelling the bullet downrange. This is different from rimfire ammo, where the primer is built into the rim. Centerfire cartridges are stronger, more reliable, and reloadable, making them the standard for most handguns, rifles, and shotguns. Common calibers include 9mm, .223 Remington, .308 Winchester, and .45 ACP.

Some popular calibers we stock are:

• .223 Remington / 5.56 NATO -- The standard for AR-15 platforms. Great for plinking, varmint hunting, and training.
• .308 Winchester / 7.62 NATO -- A classic choice for hunting and precision shooting.
• 6.5 Creedmoor -- Known for long-range consistency and flat trajectory.
• 7.62x39mm -- Reliable and affordable ammo for AK-style rifles.
• .300 AAC Blackout -- Designed for suppressed use or short-barrel rifles.
• .30-06 Springfield / .270 Win -- Time-tested for medium to large game hunting.

Choosing the Right Centerfire Ammo

Choosing the right centerfire ammo comes down to your firearm, your purpose, and performance expectations.

All firearms have a definite caliber. You can generally find this information stamped on the barrel or in the owner's manual.

• Self-defense: Use expanding hollow-point ammo (Hornady Critical Duty, Speer Gold Dot, Federal HST).
• Target Practice: Use inexpensive full metal jacket (FMJ) rounds (Blazer, Winchester, PMC).
• Hunting: Use soft-point or ballistic tip ammo, caliber based on game (.308 for deer, .30-06 for larger game).
• Precision/Competition: Use match-grade ammo for accuracy.

Tips: Do NOT guess the caliber. Do NOT substitute a cartridge that looks similar to the one you believe you are using. It can be absolutely dangerous. If your firearm is a semi-auto rifle in 5.56 NATO, then you should know that it typically can be used for .223 Rem, but NEVER the other way around, unless specifically stated.

Something to take into consideration is the type of firearm and barrel length. Shorter barrels might benefit from faster, lighter rounds, and longer barrels can utilize the slower-burning powder associated with heavier hunting or long-range rounds. Some firearms are also capable of handling higher-pressure loads that are designated as P or magnum cartridges, but only use these loads if your firearm is rated for them.

Centerfire Ammo FAQs

What is the main difference between centerfire and rimfire ammunition?

The key difference between centerfire and rimfire ammo lies in the primer placement within the cartridge. While centerfire cartridges feature a primer at the center for reliable ignition and reloading capabilities, rimfire ammo has the primer along the edge (or rim), limiting its power and reusability.

Are centerfire cartridges reloadable?

Yes, centerfire cartridges are reloadable if the casing isn't damaged from previous use. You can easily replace the primer, refill the case with gunpowder, and add a new bullet, making it a cost-effective option for frequent shooters.

What are the advantages of using centerfire ammunition?

• Primer positioned at the center of the cartridge base for reliable ignition
• Higher pressures allowed for enhanced power and performance
• Easy reloading process for convenience and efficiency
• A wide range of caliber options available for versatility in shooting activities
• Optimal choice for target practice, hunting expeditions, and diverse shooting needs

What factors should be considered when selecting centerfire ammo for a specific purpose?

When choosing what ammunition to buy, the factors to consider are:

• bullet weight
• bullet type (hollow point or full metal jacket)
• intended use (target shooting, hunting, or defense)
• the manufacturer's reputation for quality and consistency

Can centerfire ammo be used in all firearms of the same caliber?

While centerfire ammo of the correct caliber can generally be used in firearms designed for that caliber, it's crucial to ensure compatibility based on factors such as bullet shape, weight, cartridge dimensions, and the firearm's specifications to prevent malfunctions or damage.
