5.56x45MM PENETRATOR GREEN TIP #M855 (SS109) IN AMMO CAN (420 ROUNDS)

This case of 420 rounds of 5.56 NATO "green tip" ammunition comes packaged bachelor party style: in a can of strippers! The 10-round stripper clips and the included stripper clip guide make it easy to load up your AR-15 mags (compatible with USGI and Magpul PMAG designs as well as many others). This ammo comes from Lake City Army Ammunition Plant in Independence, Missouri, where it is produced by Federal Premium Ammunition, the plant's contract operator. It meets the military's M855 standard and uses 62 grain SS109 bullets, non-corrosive Boxer primers, and reloadable brass cases. The handy mil-spec ammo can comes sealed up and is reusable for other purposes once you've consumed the contents.

Since this is 5.56 NATO ammunition, you may want to check with the manufacturer of your firearm before using it in a .223 Remington rifle.

    I have to say the price, quickness, and items included in this deal were very nice. The only problem is I checked my ammo when I got it and two rounds had large dents in the brass making them unsafe to shoot. This was my first time ordering from Ammoman. I would like to think this was a fluke, but I will be more cautious if I order again.

    while I ordered 900 rounds in a 50 caliber ammo can from Ammoman, which is what I am reviewing. I also
    have the same rounds in a 30 caliber ammo can. Accuracy from my M4 shooting through an Eotech
    scope is MOA, No function problems. The free and fast delivery is the best.

    Ammoman.com hands down has the lowest prices and the fastest shipping. The XM855 performed top-notch. Will be buying here from now on. These other companies need to take notes from you guys on how to start shipping products out. Still wish y'all would start carrying the 5.56 tracer rounds.

AmmoMan.com stocks ammo from more than a dozen brands, from Winchester ammunition and other major U.S. manufacturers to imported steel-cased options. Match an ammo brand to caliber, budget, and use case below, then shop the in-stock selection. Every listing shows the regular price and the unit price (cost per round), so it's easy to compare brands before checkout. Orders over $99 ship free, and returning customers earn rewards on every order, whether buying a single box or stocking up in bulk.

How to Choose an Ammo Brand

Match the Brand to Your Caliber

Not every brand makes every caliber. Winchester and Federal cover the widest range: pistol, rifle, rimfire, and shotgun. Wolf and Tula run steel-cased rifle ammo in 7.62x39 and 5.45x39 at a lower cost per round. Speer and Hornady are the go-to names for defensive handgun loads. Start on the caliber page for the specific firearm, then compare which brands are in stock and at what price per round.

AmmoMan.com breaks stock down by caliber as well as by brand. Shoppers who already know what they're loading can go straight to that caliber's page and compare brands there: 9mm ammo, 10mm ammo, 40 S&W ammo, 45 ACP ammo, 223/5.56 ammo, 308 ammo, 7.62x39 ammo, and 300 Blackout ammo each list current stock and price per round across every brand carried in that caliber. Coming back the other way works too. A shooter who likes a brand's 9mm load can check this page to see whether that same brand also makes ammo for their rifle.

Match the Brand to Your Use Case

Range and training ammo is a cost-per-round game. Wolf, Magtech, and PMC are the common picks for high-volume shooting and sport shooting leagues that go through a case at a time. Personal defense and duty ammo is judged on terminal performance instead: Federal HST, Speer Gold Dot, and Hornady Critical Defense are the names that show up most in that category. Hunting ammo depends on the game and the caliber, with Federal, Winchester, and Hornady all running dedicated hunting lines. Precision and competition shooting runs on a different standard: round-to-round consistency matters more than price per round. Black Hills built its reputation on match-grade accuracy, and Winchester's newer Supreme Long Range line targets that same long-distance crowd. Once a brand fits the caliber and budget, check current stock before checkout, since availability shifts often.

Top Ammo Brands at AmmoMan.com

Federal Ammo

Federal makes pistol, rifle, rimfire, and shotgun ammo out of Anoka, Minnesota. The Premium line, including HST self-defense ammo and Gold Medal Match rifle ammo, is a common pick for law enforcement contracts and competition shooters. Shop Federal ammo.

Shop Winchester ammo.

Frequently Asked Questions

What is the most reliable ammo brand?

Reliability depends on caliber and application. For personal defense, Federal, Speer, and Hornady all have strong track records in law enforcement testing. For range training, PMC, Magtech, and Winchester White Box run consistently across a wide range of firearms, from sport shooting leagues to weekend range trips.

Is foreign-made ammo as good as American-made ammo?

Foreign manufacturers like Sellier & Bellot, Fiocchi, Magtech, and Prvi Partizan build to the same SAAMI or CIP pressure standards as American brands, and they're widely used for range training. Some shooters still prefer American-made brass-cased ammo for hunting and personal defense. U.S. and other NATO forces even use ammo made by foreign brands like PMC in the Pacific.

What's the difference between steel-cased and brass-cased ammo brands?

Steel-cased ammo brands like Wolf and Tula cost less per round and hold up fine for high-volume range days, though steel cases don't reload as well as brass. Brass-cased ammo brands, including Federal, Winchester, PMC, and Hornady, cost more but run cleaner and stand up better to reloading. For personal defense or hunting, brass-cased ammo is the safer default. For a weekend at the range, steel-cased ammo saves money without giving up much.

Which brands are best for buying in bulk?

Case-quantity pricing matters most for range and training rounds fired by the hundreds, and Wolf, Tula, PMC, and Magtech all price down as quantity goes up. Orders over $99 ship free no matter which brands end up in the cart, so combining brands into one order beats checking out separately. Manufacturers also run mail-in rebate promotions from time to time, so it can pay to check for a current rebate on a given brand before buying.

Does brand matter more than bullet type?

Bullet type, like FMJ, JHP, or soft point, usually matters more than brand for picking the right ammo for the job. Once the bullet type is set, the brand choice is really about reliability and price per round.

Stock turns over as each brand runs through production, so the fastest way to find the right ammo brand for a specific gun is to filter by caliber and check what's currently in stock above.
