Federal Premium .223 Remington 55 Grain FMJBT: Product Information
The Federal Premium .223 Remington 55 grain Full Metal Jacket Boat Tail (FMJBT) Brass Centerfire Rifle Ammunition 500 RDS is a rifle-ammunition configuration built around the widely used .223 Remington cartridge and a 55-grain full-metal-jacket projectile. The FMJ design features a jacket surrounding the projectile, while the boat-tail profile tapers toward the rear of the bullet. A brass centerfire case completes the cartridge assembly.
For anyone researching 223 Remington 55 grain ammunition, understanding the projectile design, cartridge construction, and intended application is important. Always verify firearm compatibility and follow the manufacturer’s specifications and applicable local laws before handling ammunition.

- Case material: Brass
- Primer configuration: Centerfire

Benefits
The 55-grain projectile is a commonly encountered bullet weight within the .223 Remington cartridge family. Its widespread use means shooters may encounter similar 223 Remington 55 grain full metal jacket configurations from multiple manufacturers.
The FMJ construction provides a jacket around the projectile rather than exposing the projectile material along most of its exterior surface. The boat-tail design distinguishes this configuration from a traditional flat-base projectile by tapering the rear portion of the bullet.
Brass cases are also a familiar component of centerfire rifle ammunition. Their use makes the cartridge readily identifiable as a conventional brass-cased .223 Remington load.
It is worth distinguishing this product from other cartridges and projectile constructions that may appear in search results. For example, Federal Premium 223 ammo can refer to several different loads, including configurations with different bullet weights and projectile designs.

How to Use
Before handling or loading any ammunition, confirm that the cartridge marking corresponds exactly to the chambering specified for the firearm.
For this product:
- Verify that the firearm is specifically chambered for .223 Remington.
- Inspect cartridges for visible damage before use.
- Follow the firearm manufacturer’s operating instructions.
- Ammunition should not be exposed to heat, moisture, or unauthorized people.
- Use appropriate eye and hearing protection when operating a firearm.
- Follow all applicable laws, regulations, range rules, and manufacturer guidance.

Understanding Similar .223 Remington Searches
Searches such as 223 remington 55 gr fmj ammo for sale, 223 remington 55 grain fmj ammo for sale, remington 223 55 grain, and remington 223 ammo 55 grain can refer to a variety of products. Product names should therefore be checked carefully rather than treated as interchangeable.
The term remington 223 55 grain commonly describes the cartridge and projectile weight, while remington 223 55 grain psp refers to a different projectile designation. PSP generally indicates a pointed soft-point configuration, which should not be confused with FMJBT construction.
Likewise, references to federal premium law enforcement 223 55 grain or federal premium le 223 55 grain may identify other Federal ammunition configurations. A listing mentioning federal premium 223 55 grain tsx is also describing a different projectile type from the FMJBT configuration discussed here.
Search terms such as federal premium le 223 55 grain sierra bthp similarly point toward a different projectile design. Comparing the exact cartridge designation, bullet construction, weight, and manufacturer’s specifications is therefore essential.
Why Choose This Product?
For product identification purposes, this Federal Premium configuration combines several straightforward characteristics: a .223 Remington cartridge, a 55-grain FMJBT projectile, a brass case, and a centerfire primer.
Its specifications make it relatively easy to distinguish from other .223 Remington loads that use different projectile weights or constructions. Buyers and firearm owners should rely on the manufacturer’s published specifications and their firearm’s documentation rather than assuming that all .223 Remington ammunition is identical.
FMJBT Terminology Explained
Understanding the abbreviation can make product specifications easier to interpret:
- FMJ: Full Metal Jacket
- BT: Boat Tail
- FMJBT: Full Metal Jacket Boat Tail
- 55 grain: Stated projectile weight
- Brass: Case material
- Centerfire: Primer arrangement in which the primer is located centrally in the cartridge base
This terminology can also help prevent confusion when researching related 223 Remington 55 grain products.
Brass Case Characteristics
The cartridge uses a brass case, a material commonly found in centerfire rifle ammunition. Brass provides the structural body of the cartridge and contains the primer, propellant, and projectile.
When inspecting ammunition, look for obvious defects such as significant dents, corrosion, damaged case mouths, or other abnormalities. Damaged ammunition should not be used.
Storage and Handling
Proper storage is an important part of responsible ammunition ownership. Ammunition should generally be kept:
- In a cool, dry environment
- Away from excessive heat and moisture
- In its original packaging or an appropriate ammunition container
- Away from children and unauthorized individuals
- Separate from sources of ignition
- in compliance with the manufacturer’s recommendations and any applicable legislation
Avoid exposing cartridges unnecessarily to water, solvents, oils, or other substances that could affect cartridge components.
Compatibility Considerations
Although 223 Remington 55 grain is a familiar cartridge description, ammunition compatibility should always be determined from the firearm manufacturer’s specifications.
Do not assume that cartridges are interchangeable simply because their names or dimensions appear similar. Check the firearm’s markings and owner’s manual before using any ammunition.
This is particularly important when comparing .223 Remington with other cartridges that may appear similar but have different chambering specifications.
