Ultra Mega Milspec Gongs

Yes, targets can be shot with any ammo under 1750 foot pounds of energy and under 2850 feet per second (this is at the steel).

If you follow both rules above these targets will last a lifetime.

For 5.56/.223 (16" barrel, 55g ammo), stay 115-125 yards away to keep speed below 2850 fps or you will pit your targets.

If you exceed 1750 ft-lbs use 3/8" Ultra Mega Gongs instead.

The 1/4" has a maximum FPE rating of 1000 and  is perfect for all handguns except the hand cannons like 44 Mag, etc.

Many customers also use it for rimfire and air gun.

🔥 MIL-A-46100E vs. AR500: What’s the Difference? 🔥

It all boils down to specs and purpose—especially when it comes to consistency and toughness! 💪

🛡️ MIL-A-46100E: The Military Muscle

• What is it? A Mil-Spec armor steel, stamped with approval by the U.S. Department of Defense 🇺🇸 for serious combat action.

• Hardness: Locked in at 477-534 BHN (Brinell Hardness Number). Tough as nails! 💥

• Superpower: It’s crazy consistent—the whole plate is uniformly tough, soaking up impacts without cracking or shattering.

• Why it rocks: Perfect for tanks, armored rides, or stopping speedy projectiles dead in their tracks! 🚀

🎯 AR500: The Everyday Warrior

• What is it? An abrasion-resistant steel with a hardness of about 470-540 BHN. Not tied to strict rules!

• Vibe: Built for commercial use—think shooting targets 🎯 or body armor you’d grab off the shelf.

• Catch: Toughness and quality can vary depending on who makes it. No military babysitting here!

• Weak spot? Some AR500 might crack under big hits (like an M80 bullet 💣) if it’s not tough enough.

🌟 The Bottom Line

• MIL-A-46100E: Military-grade beast 🏅—regulated, reliable, and ready for war with top-tier hardness AND toughness.

• AR500: A solid all-rounder ✨—hard as heck but less predictable, made for civilian life.

So, MIL-A-46100E is the elite soldier 🪖, while AR500 is the scrappy fighter 🥊—both tough, but built for different battles!

Yes, but it is the closest fractional size that people will recognize. If I said 19/64" (the closest fraction) few would be able to relate to it. This steel is from a DOD contract and was made to their specific specs.
