Understanding Mild Steel for Steel Targets

Mild steel is a budget-friendly material with a lower carbon content (around 0.05%–0.25%) that makes it soft, malleable, and easy to fabricate. While it’s not as durable as AR450 or AR500, mild steel is perfectly safe and effective when used within its limitations, particularly for low-velocity ammunition like .22LR.

Key Points About Mild Steel

  1. Softness and Durability:

    • Mild steel is more prone to denting and wear, but this is manageable if used with low-velocity rounds at safe distances.
    • Over time, impacts may cause pitting or cratering, so regular inspection is recommended.

  2. Cost-Effectiveness:

    • It’s an affordable option for casual plinking or training and ideal for beginners.

  3. Ammunition Guidelines:

    • Best for standard-velocity .22LR ammunition (under 1,200 fps).
    • Unsuitable for higher-energy rounds like magnum rimfire or centrefire ammunition.
    • Minimum Bullet Velocity: A bullet should ideally travel at least 400–500 feet per second (fps) to properly deform or fragment upon impact. Lower velocities might not generate enough energy to fragment and could result in ricochet or bounce-back, especially with softer lead or full-metal jacket rounds. Keeping the minimum velocity to 800fps reduces the chance of incorrect fragmentation/projectile deflection.

  4. Safety Considerations:

    • Targets should be angled downward to direct fragments safely toward the ground.
    • Maintain Minimum safe shooting distance: 25+ meters for angled targets and 50+ meters for vertical targets.
    • Need the target closer? For close distance target engagement requirements, consider using AR450 OR AR500, as Hardened steel can be safely used at closer distances compared to Mild steel. (please refer to our Safety, Distance and Calibre Rating Page)

Applications for Mild Steel

  • Great for Rimfire Shooters: A perfect entry-level option for .22LR rifles and handguns.
  • Temporary Use: A low-cost solution for short-term shooting activities or light target practice.

Comparison: Mild Steel vs. AR500

Feature Mild Steel AR500 Steel
Hardness (BHN) 120–160 500+
Suitable Ammo Low-velocity (.22LR) Wide range (rimfire to magnum rifles)
Durability Moderate for .22LR High
Cost Low Higher upfront, longer-lasting
Risk of Ricochet Manageable with care Low (if maintained properly)

In Conclusion

Mild steel is a safe and practical choice for shooting with standard-velocity .22LR ammunition. It’s an affordable option for casual shooters, beginners, or those looking for temporary targets. While not as durable as AR450 or AR500, mild steel can still provide plenty of shooting fun when used responsibly and maintained properly.

For those planning to shoot larger calibres or higher-velocity rounds, upgrading to hardened steel like AR450 or AR500 is the better choice for long-term durability and safety.
