AR500 vs AR550 Steel Targets: Which One Should You Actually Buy?

The real difference in the AR500 vs AR550 debate comes down to hardness, durability, and lifespan under high-velocity impacts. AR500 steel targets are the industry standard and handle most pistol and rifle use, while AR550 steel targets offer increased hardness and longer life, especially under repeated hits from fast rifle rounds like 5.56 and .308.

If you're trying to decide between AR500 and AR550, you're already asking the right question. The steel you choose directly impacts safety, longevity, and how much you spend over time replacing damaged targets.

Both materials are abrasion-resistant steel, but they are not equal. Choosing the wrong one for your setup can lead to premature wear, pitting, or unsafe shooting conditions.

What Is AR500 Steel?

AR500 stands for “Abrasion Resistant” steel with a hardness rating around 500 Brinell. It has become the standard material for steel targets because it balances durability, cost, and performance.

• Hardness: ~500 BHN
• Best for: Pistols and moderate rifle use
• Common thickness: 3/8″ and 1/2″
• Cost: Lower than AR550

For most shooters, AR500 will handle thousands of rounds without issue when used correctly.

What Is AR550 Steel?

AR550 is a harder, more durable version of abrasion-resistant steel. It is designed to better withstand high-velocity impacts and reduce surface deformation over time.

• Hardness: ~550 BHN
• Best for: Rifle-heavy use and high round counts
• Advantage: Increased resistance to pitting and cratering
• Cost: Higher upfront

AR550 is the better choice if you regularly shoot fast rifle calibers or want maximum lifespan from your targets.

AR500 vs AR550: Side-by-Side Comparison

Which Steel Should You Use for Different Calibers?

9mm and Pistol Calibers

• AR500 is more than sufficient
• Minimum distance: 10 yards
• Minimal wear when used correctly

5.56 / .223

• AR500 works, but AR550 lasts longer
• Minimum distance: 100 yards
• High velocity increases wear

.308 and Larger Rifles

• AR550 strongly recommended
• Minimum distance: 100–200 yards
• Greater energy transfer = faster degradation on softer steel

Safety Considerations (Critical)

No matter which steel you choose, safety comes down to proper setup and usage.

• Always angle targets downward to deflect fragments
• Never shoot steel with armor-piercing or steel-core ammo
• Maintain proper distance based on caliber
• Inspect for pitting or cratering regularly

Even AR550 can become unsafe if misused.

Common Mistakes That Destroy Steel Targets

• Shooting rifle rounds at close range
• Using the wrong thickness
• Buying cheap, non-hardened steel
• Improper mounting (rigid vs hanging)

These mistakes cost more over time than investing in the right steel upfront.

What Should You Actually Buy?

Choose AR500 if:

• You primarily shoot pistols
• You want a cost-effective option
• You shoot occasionally or recreationally

Choose AR550 if:

• You shoot rifle calibers frequently
• You want maximum durability
• You run high round counts or train regularly

The Long-Term Cost Difference

AR550 costs more upfront, but lasts significantly longer under heavy use. That means fewer replacements and better long-term value.

AR500 is still the best entry point for most shooters, but frequent rifle users will quickly see the benefit of upgrading.

Frequently Asked Questions

Is AR550 worth the extra cost?
Yes, if you shoot rifle rounds regularly, AR550 will last longer and resist damage better.

Can AR500 handle 5.56?
Yes, but only at proper distances. Over time, repeated impacts will wear it faster than AR550.

What happens if steel targets get pitted?
Pitting can cause unpredictable bullet fragmentation and should be avoided for safety reasons.

What thickness should I choose?
3/8″ is common for pistols and light rifle, while 1/2″ is better for heavier rifle use.

Is AR550 safer than AR500?
Both are safe when used properly, but AR550 maintains a smoother surface longer, reducing risk over time.

Bottom line: If you want the best balance of cost and performance, AR500 is the standard. If you want maximum durability and shoot rifle calibers often, AR550 is the smarter investment.
