The Winchester USA .223 Remington 55 Grain Full Metal Jacket (FMJ) cartridge is a centerfire rifle ammunition product manufactured under the Winchester USA line. The listed configuration uses a 55-grain FMJ projectile and is specified for the .223 Remington cartridge. The package information provided indicates a 1,000-round quantity.

Winchester USA Ammunition Terminology
The Winchester USA range includes ammunition products in several calibers and configurations. Searches may also refer to terms such as Winchester USA ammo, Winchester USA 250 ammo, or Winchester USA target FMJ centerfire rifle ammo.
Other Winchester product terminology can refer to different cartridges and applications, including Winchester USA 9mm 147 grain handgun ammo, Winchester USA forged 9mm ammo, Winchester ammo 45 ACP USA 185gr FMJ, and 270 Winchester ammo. These should not be treated as interchangeable with .223 Remington ammunition because cartridge dimensions, firearm compatibility, and intended specifications differ.
Our 22-250 ammo 500 rounds page provides additional product and cartridge information.
Safety and Compatibility
Always verify the cartridge designation marked on the ammunition and firearm before handling or use. Ammunition should only be used in a firearm specifically chambered for that cartridge, following the firearm manufacturer’s instructions and applicable laws.
Store ammunition securely, away from children, unauthorized users, excessive heat, moisture, and open flames. Inspect cartridges for visible damage and follow applicable manufacturer and local safety guidance.
Product Construction
The Winchester USA .223 Remington 55 Grain FMJ is identified by a conventional full-metal-jacket projectile design. The jacket covers the projectile’s lead core, creating a distinct construction from expanding bullet designs such as hollow-point and soft-point projectiles.
The 55-grain specification identifies the projectile weight and provides a useful reference when comparing different .223 Remington ammunition loads. Because ammunition can vary considerably in projectile design, weight, and loading specifications, the exact markings on the cartridge packaging should always be used when identifying a particular load.
Package Quantity
The listed configuration contains 1,000 rounds. A large package quantity is primarily a packaging characteristic and should not be interpreted as an indication of performance or suitability for a particular firearm.
For inventory purposes, the package specification can help distinguish this configuration from smaller Winchester USA packages, including listings that reference Winchester USA 250 ammo.
Winchester USA Product Family
Winchester USA is a broad ammunition product line covering multiple cartridge types. Consequently, similar search terminology can refer to products with substantially different specifications.
For example, terms such as Winchester USA forged ammo, Winchester USA ready handgun ammo – 9mm, and Winchester USA ready rifle ammo describe other product categories or configurations rather than this specific .223 Remington 55-grain FMJ cartridge.
Likewise, searches for Winchester USA ready 9mm ammo for sale, Winchester USA ready defense ammo for sale, or Winchester USA ready ammo for sale should be evaluated separately because those terms may refer to different Winchester ammunition products.
Cartridge Identification
Correct ammunition identification is particularly important because cartridges that appear visually similar can have different chambering specifications. The product information supplied for this listing identifies the cartridge as .223 Remington.
Before handling ammunition, users should check:
- The cartridge designation printed on the ammunition packaging.
- The chambering marked on the firearm.
- The firearm manufacturer’s instructions.
- Applicable local, state, and federal regulations.
- The ammunition manufacturer’s published specifications.
Never rely solely on appearance when determining cartridge compatibility.

FMJ Explained
Full Metal Jacket is a projectile construction rather than a caliber. Therefore, FMJ ammunition can be found in numerous cartridges, including both rifle and handgun ammunition.
In this product’s case, FMJ describes the projectile construction while .223 Remington identifies the cartridge. The 55-grain specification identifies the projectile weight, and the 1,000-round specification identifies the package quantity.
These terms work together to describe the product:
| Specification | Listed Information |
|---|---|
| Brand | Winchester |
| Product Line | USA |
| Cartridge | .223 Remington |
| Projectile Weight | 55 grains |
| Projectile Type | FMJ |
| Quantity | 1,000 rounds |
| Ammunition Category | Centerfire rifle ammunition |
Important Storage Considerations
Ammunition should be stored responsibly in accordance with manufacturer recommendations and applicable regulations. A suitable storage environment should protect ammunition from unnecessary exposure to moisture, excessive heat, and other potentially damaging conditions.
Keep ammunition secured from children and unauthorized individuals. Original packaging can also help preserve product identification information, including cartridge designation, projectile weight, manufacturer information, and lot details.
Product Identification Summary
For cataloging and inventory purposes, the supplied information identifies this product as a Winchester USA .223 Remington 55 Grain FMJ 1,000-round configuration. The product should be distinguished from other Winchester USA listings based on caliber, projectile weight, projectile construction, and package quantity.
Terms such as Winchester USA ammo, Winchester USA target FMJ centerfire rifle ammo, and Winchester USA 250 ammo may describe related Winchester products, but they should not be assumed to represent the same configuration without checking the complete specifications.
