When preparing for survival situations, most people think of the typical heavy hitters like the .308 or the 9mm. But in a true survival scenario, versatility, availability, and efficiency often matter more than sheer firepower. Having a well-rounded selection of firearms in underrated calibers could be the edge that helps you navigate the unexpected. As a prepper, I’ve always believed that choosing the right calibers is crucial, not just for defense, but for hunting, trading, and even conserving precious resources. Here’s a look at some of the most underrated, yet extremely useful, calibers for survival situations.
.22 Long Rifle (LR)
The .22 LR might be small, but it’s reliable and widely available. It’s perfect for small game hunting, meaning you can sustain yourself without wasting larger, more powerful rounds. This caliber also has virtually no recoil, making it easy to use for beginners or in situations where conserving energy is critical. Plus, you can carry hundreds of rounds without being weighed down.
.17 HMR
The .17 Hornady Magnum Rimfire (HMR) is a lightweight, accurate round that flies incredibly fast. Ideal for small game and varmints, this round provides great performance at a distance. While not as common as the .22 LR, the .17 HMR is an underrated gem for survivalists looking for precision and stopping power with minimal recoil.
.30-30 Winchester
The .30-30 Winchester might not be the trendiest choice, but it’s a dependable workhorse for medium-sized game like deer. In a pinch, it can also serve as a defensive round. Ammunition is often available in rural areas, making it a solid option if you’re living or bugging out away from urban centers. The lever-action rifles chambered in .30-30 are known for their rugged durability, too.
.357 Magnum
The .357 Magnum is one of the most versatile handgun calibers out there. Not only is it powerful enough for self-defense, but it’s also capable of taking down medium game at closer ranges. Another advantage is that most revolvers chambered for .357 can also shoot .38 Special rounds, giving you flexibility with your ammunition.
.223 Remington
While the .223 Remington is well-known in tactical circles, it’s often overlooked for survival situations due to its association with the AR-15. But its versatility makes it ideal for survivalists. It’s a capable round for hunting medium game, and in defensive scenarios, its high velocity and relatively light recoil allow for quick follow-up shots.
12 Gauge Shotgun
While not technically a caliber, the 12-gauge shotgun deserves a place here. Its ability to fire a wide variety of loads, from birdshot to buckshot and even slugs, makes it one of the most versatile options for survival. You can hunt almost any type of game with a 12-gauge and defend yourself effectively, all with one firearm.
7.62x39mm
Known mostly for its use in AK-47-style rifles, the 7.62x39mm is a powerful and affordable caliber that works well in survival situations. This round provides a good balance between range, power, and availability. It can take down large game and offers solid performance in defensive situations, making it a great all-around survival caliber.
.308 Winchester
The .308 Winchester is often overshadowed by its cousin, the .30-06, but it’s a strong contender for survival purposes. It’s great for hunting large game at longer distances, and it’s widely available. While its recoil is heavier than some of the other rounds on this list, its power and versatility make it a must-have in a survival arsenal.
.40 S&W
Often overshadowed by the 9mm and the .45 ACP, the .40 S&W sits in a happy medium between power and control. It offers more stopping power than the 9mm without the heavier recoil of the .45 ACP. Many law enforcement agencies once favored this round, so ammunition can still be found in surplus.
.410 Bore
Like the 12-gauge, the .410 Bore is a shotgun caliber, but its lower recoil and smaller size make it a fantastic choice for survivalists. It’s a great option for small game hunting and can be used for self-defense when needed. Best of all, it’s incredibly lightweight, allowing you to carry more ammo without being bogged down.
.22 WMR (Winchester Magnum Rimfire)
The .22 WMR is often overlooked in favor of its smaller sibling, the .22 LR, but it offers greater stopping power and range. It is excellent for small game hunting and can even be used for self-defense in a pinch. Its flat trajectory and extended range make it a great option for longer-distance shots. Plus, it’s lightweight and versatile, making it an excellent addition to any survival kit.
.45-70 Government
The .45-70 Government is a powerful, time-tested round, ideal for hunting large game like elk, moose, or bear. Lever-action rifles chambered in this caliber are known for their durability and reliability in harsh wilderness environments. While heavy and more suited for rural or wilderness survival situations, the stopping power of this round makes it invaluable when dealing with large, dangerous animals.
.243 Winchester
The .243 Winchester is well-known among hunters for its flat shooting trajectory and manageable recoil. It’s a versatile caliber, perfect for hunting medium game like deer or wild boar. It can also be used for varmint control, adding to its practicality in a survival scenario. Its ease of use and effectiveness at both short and long ranges make it a smart choice.
.22 Hornet
The .22 Hornet is a lesser-known but highly effective caliber for small to medium game hunting. It offers higher velocity and better range than the .22 LR, making it great for situations where you need to hit a target from a distance. Its lightweight ammo and high availability make it an attractive option for preppers looking for something between a .22 LR and larger rounds like the .223.
6.5 Creedmoor
Though rising in popularity among long-range shooters, the 6.5 Creedmoor is still an underrated option in survival circles. It’s capable of taking down large game like deer or elk, and its low recoil makes it easier to handle compared to other larger calibers. If you find yourself needing a round that can cover long distances with precision, the 6.5 Creedmoor is a fantastic choice.
