Winchester M193 5.56mm ammunition is a trusted choice for AR-15 shooters, trainers, and recreational shooters who need dependable centerfire rifle rounds without the premium price tag. This 500-round bulk pack — delivered as two 250-round boxes — gives you a straightforward, no-frills option for high-volume shooting, whether you're zeroing at the range, running defensive drills, or building your ammunition stockpile. The M193 has been a NATO standard load for decades, and Winchester's version maintains that reputation for consistent performance and reliable function across a wide range of modern sporting rifles.
Built with a 55-grain full metal jacket (FMJ) bullet and boxer-primed, reloadable brass casings, this ammunition is engineered for function and repeatability. The FMJ construction means cleaner shooting indoors and at most ranges, and the round's ballistics are well-suited to mid-range training and recreational shooting. Winchester doesn't skimp on quality control even in bulk offerings, so you get the same level of care in loading and inspection that shooters have relied on for generations.
When you're buying 500 rounds at a time, consistency and reliability matter more than exotic performance claims. M193 delivers both, making it a smart choice for shooters who need ammunition they can count on, shoot regularly, and not lose sleep over the cost per round. If you're serious about training volume, building reserves, or simply shooting without breaking the bank, this bulk pack of Winchester M193 makes logistical and financial sense.

Yes. M193 is a standard 5.56mm NATO round and will function reliably in any AR-15 or other rifle chambered in 5.56mm NATO. It is not compatible with rifles chambered only in .223 Remington, though many modern rifles handle both interchangeably — check your rifle's markings if you're unsure.
Yes. This ammunition comes with Boxer-primed brass cases, which can be reloaded using standard reloading equipment and components.
This ammunition uses a 55-grain full metal jacket (FMJ) bullet, which is the classic M193 specification. FMJ construction provides reliable feeding, is generally acceptable at indoor and outdoor ranges, and is suitable for training and recreational shooting.
The Winchester Ammo Win Wm193500 comes as two 250-round boxes, making it easy to store or share while still getting the bulk discount of a 500-round case.
