The Sterling M193 delivers what 5.56 shooters have trusted for decades. These 55-grain full metal jacket cartridges are built for high-volume range sessions without the cost headache of reloading brass.
This is M193 spec ammunition, which means you're getting the classic military load that set the standard. Loaded to 3250 feet per second, the 55-grain projectile prints flat trajectories at typical range distances and feeds reliably through modern AR-15 platforms regardless of your barrel twist rate. You won't deal with feeding issues or mysterious jams that waste range time.
Sterling uses modern non-hygroscopic primers that resist corrosion, so your ammunition stores well whether it sits in a safe or a range bag. The brass cases are new and consistent. Since this ammunition isn't reloadable, you can focus entirely on shooting instead of thinking about brass prep and sizing. Each 30-round box is straightforward and convenient for a session at the range or stocking up for later.
M193 is the lighter, faster sibling in the 5.56 family and remains the baseline choice for general-purpose shooting. The 55-grain bullet sheds velocity quickly downrange, so this performs best inside 300 yards where it stays supersonic and maintains good energy. For casual plinking and marksmanship practice, this is exactly what you need. Groups will be respectable, reliability will be solid, and you'll save money compared to premium loads.
Yes. The Sterling M193 is loaded to 5.56 NATO specifications and will function reliably in any AR-15 chambered in 5.56 NATO or .223 Wylde. If your rifle is marked only for .223 Remington, check your manual first since it may have tighter pressure tolerances. Most modern AR-15s handle this ammunition without any issues.
No, Sterling M193 is non-reloadable. The ammunition is designed as a one-time use round, so you won't be collecting brass to reload. This keeps costs down and makes it convenient for high-volume shooting sessions where you just want to focus on pulling the trigger.
The 55-grain M193 flies faster (around 3250 fps) and delivers a flatter trajectory at shorter ranges, making it ideal for plinking and training. The heavier 62-grain bullets retain energy better at distance and handle wind drift better, but they cost more. For target practice and breaking in a new rifle, 55-grain M193 is the traditional choice.
Keep it in a cool, dry place away from moisture and extreme temperature swings. The non-hygroscopic primers resist corrosion, so storage in a safe or ammunition container works well. Don't store it loose or exposed to humidity for extended periods.
