Frequently Asked Questions

Which calibers are most likely to be affected by the next ammo shortage?

The calibers most likely to be affected by the next ammo shortage, according to Sully from Line 45, are 300 Blackout, .308 Winchester, 10mm Auto, 12 Gauge, .22 LR, .223 Remington/5.56 NATO, and 9mm Luger. These are identified due to high demand, specific use cases, or production limitations.

Why is 300 Blackout recommended for stockpiling?

300 Blackout is recommended for stockpiling because it offers unique advantages in suppressed, short-barreled firearms, providing quiet operation and effective terminal ballistics that 5.56 NATO cannot match in those specific configurations. Its versatility for different roles makes it a valuable caliber to have on hand.

What makes .308 Winchester a critical caliber to stock?

.308 Winchester is a critical caliber to stock due to its exceptional versatility, serving effectively for long-range shooting, hunting, and general-purpose rifle use. Its proven reliability and widespread trust among various user groups ensure its continued relevance and demand.

Why is 9mm Luger always the first to disappear during an ammo shortage?

9mm Luger is consistently the first caliber to disappear during an ammo shortage because it is the most popular handgun caliber in the United States, used in the vast majority of firearms for self-defense, concealed carry, and training. Its ubiquity means demand is always extremely high.

What are the key differences between .223 Remington and 5.56 NATO?

.223 Remington is typically loaded to lower pressures and used in firearms chambered specifically for it, while 5.56 NATO is loaded to higher pressures and can be safely fired from firearms chambered for 5.56 NATO (which can also fire .223 Remington). Most modern AR-15s are stamped for 5.56 NATO.
