A lot of shooters hear the same claims about 5.56 ammo again and again. Some sound convincing. Others come from old range talk. The problem is this. Myths stick around longer than facts. That can lead to bad buying choices and poor shooting habits. Let’s clear the air and talk straight about 5.56x45mm ammo and what actually matters today.

Myth 1: All 5.56 Ammo Is Basically the Same

This is one of the most common mix-ups. Yes, the caliber name stays the same. But the load does not. Bullet weight, casing quality, and purpose all change how a round behaves. A light training round feels very different from a heavier option. Even within range ammo, there are clear differences in recoil and accuracy. For example, 5.56x45mm 55gr FMJ Ammo is popular for practice because it feeds well and stays consistent. That does not mean every box labeled 5.56 will perform the same way.

Myth 2: 5.56 Is Too Powerful for Regular Range Use

Some people think 5.56 is only for tactical use. That idea is outdated. Many shooters use it every week at the range. The recoil is manageable. The round stays stable. When paired with the right rifle setup, it feels smooth and predictable. Range rules matter more than the ammo itself. As long as the range allows it, 5.56 works just fine for training sessions and skill building.

Myth 3: FMJ Rounds Are Low Quality

FMJ rounds often get labeled as cheap or basic. That is not the full story. Full metal jacket bullets are built for clean feeding and steady cycling. That is why they are so common for practice. 5.56x45mm 55gr FMJ Ammo is trusted by many shooters because it reduces feed issues and keeps performance steady shot after shot. FMJ does not mean poor build. It means practical design.

Myth 4: You Should Avoid Bulk Buying 5.56 Ammo

Bulk buying gets a bad reputation from poor storage habits. The ammo is not the issue. Planning is. If you shoot often, buying larger quantities saves time and helps avoid price swings. Proper packaging and dry storage make a real difference. Many shooters who buy from Brass Kisses appreciate sealed packaging and clear labeling, which makes bulk buying easier to manage. When storage is handled right, bulk purchases make sense.

Myth 5: 5.56 Wears Out Rifles Faster

This one worries new AR owners the most. Normal wear happens with any ammo. The key factors are maintenance and shooting habits. Clean your rifle. Use quality mags. Stick to proper firing schedules. 5.56 ammo does not damage a well-maintained rifle. In fact, many AR platforms are built specifically around this caliber. Consistent care matters far more than the ammo choice itself.

Why These Myths Keep Coming Back

Old advice spreads fast. Online forums repeat the same lines. New shooters hear them and assume they are true. The reality is simpler. Modern 5.56x45mm ammo is made with better consistency than ever before. Manufacturing standards have improved. Packaging is stronger. Quality control is tighter. Retailers like Brass Kisses focus on clean storage and reliable sourcing, which helps shooters avoid common problems tied to poor handling.

What Shooters Should Focus On Instead

Instead of myths, focus on fit and use. Ask simple questions. How often do you shoot? Is this for range time or storage? Does your rifle cycle smoothly with this load? These answers matter more than internet opinions. Trying a few options helps build confidence. Over time, patterns become clear.
