If you’ve spent any time in the firearms world lately, you know that "preparedness" isn't just a buzzword anymore: it’s a lifestyle. Whether you’re worried about supply chain disruptions, sudden price hikes, or just want to make sure you have enough for your next high-volume training class, having a solid "stack" of ammunition is the foundation of any survival plan.
But you shouldn't just buy random boxes of whatever is on the shelf. To really succeed with survival prep, you need a strategy. In this guide, we’re going to break down why 9mm and 5.56 NATO are the "gold standard" for stacking, how to store them so they last for decades, and how to round out your inventory with essential extras without breaking the bank.
When it comes to survival prep, logistics is the name of the game. You want calibers that are common, versatile, and: most importantly: easy to find.
9mm Luger is the most popular handgun caliber in the world. It’s the standard for law enforcement, military, and civilian self-defense. This means that in a "worst-case" scenario, 9mm is the caliber you are most likely to find or trade for. It’s also relatively compact, meaning you can fit a lot of it in a standard ammo can without taking up too much room.
5.56 NATO (and its civilian cousin, .223 Remington) is the rifle equivalent. It’s the standard chambering for the AR-15, the most popular rifle platform in America. It’s lightweight, has a flat trajectory, and is effective for everything from home defense to small-to-medium game hunting in a pinch.
By focusing your "deep storage" on these two calibers, you simplify your life. You only need two sets of cleaning kits, two types of magazines, and two main line items in your ammo budget.
A common mistake new preppers make is buying 1,000 rounds of the cheapest steel-cased ammo they can find and calling it a day. While that's better than nothing, a pro-level stack is split into two categories:
A pile of ammo in the corner of a damp garage isn't a survival prep: it’s a ticking time bomb of corrosion. If you want your ammo to last 20+ years (and it definitely can), you need to follow the three rules of storage:
Military-style metal ammo cans are the gold standard for a reason. They have a rubber gasket in the lid that creates an airtight seal. If you can’t get metal, high-quality plastic cans with similar gaskets work well too. Avoid leaving ammo in the original cardboard boxes on an open shelf; cardboard absorbs moisture from the air.
Every time you seal an ammo can, throw in a couple of silica gel desiccant packs. These will soak up any residual moisture trapped inside the can. You can even find "rechargeable" desiccants that you can dry out in the oven and reuse.
Big swings in temperature (like what you get in an attic or a non-insulated garage) can cause the powder and primers to degrade over time. The best place for your stack is a climate-controlled area inside your home, like a closet or a dry basement.
While 9mm and 5.56 are your "bread and butter," a truly prepared individual looks at the "Rule of Three": Handgun, Rifle, and Shotgun.
Many people keep a revolver as a backup or a "kit gun." If you have a .357 Magnum or .38 Special revolver, you know that ammo prices can sometimes be higher than 9mm. However, keeping a stash of cheap 38 special for practice is a smart move. Revolvers are incredibly reliable and make great "hand-out" guns for family members who might not be as familiar with semi-auto clears and malfunctions.
A shotgun is perhaps the most versatile tool in the survival shed. From home defense to harvesting birds or deer, it does it all. If you’re building your prep on a budget, look for budget shotguns that won't break the bank. At Wholesale Hunter, we offer free shipping on all long guns, which makes ordering a new pump-action or single-shot even more affordable.
To go along with that shotgun, don't forget the specialty loads. While buckshot is king for defense, having 410 slugs for sale or 12-gauge slugs in your inventory allows you to take larger game at distance if the need arises.
If you’re stacking 5.56, you’re likely running an AR-15. But what if you want something more compact? The Kel-Tec PLR-16 is a popular 5.56 pistol that uses standard AR mags, making it a great companion to your rifle.
To get the most out of a survival pistol, you’ll want to look into Kel Tec PLR 16 accessories. Adding a muzzle brake can help tame the blast of the short barrel, and a compact red dot makes it much more effective in a high-stress situation. Since it shares ammo and magazines with your primary rifle, it fits perfectly into your logistical plan.
