The Truth About Steel and Steel Targets, Pt. 2

Posted on by Marketing Action Target

When it comes to steel targets, it is important to understand there are crucial differences in the quality of the steel used to make the targets and the design of the targets themselves. In an age where it seems everyone “knows a guy” who can make steel targets for them out of a welding shop, understanding the facts about steel is even more important. Steel targets can be perfectly safe and a fantastic training tool if done right, but they can also be extremely dangerous if done wrong. Here at Action Target, we have been designing and manufacturing steel targetscart Small and tactical training systems for nearly 30 years. Here are some of the things we’ve learned along the way.

TRUTH – THERE IS A SIGNIFICANT DIFFERENCE IN THE QUALITY OF STEEL BEING USED

Unfortunately, there are steel targets out there that are poorly designed and are made of inferior steel. Homemade targets from local welding shops are usually the culprits, but some commercial target manufacturers use inferior steel as well. Because these targets are vulnerable to cratering, pocking, and general deformation, they are very dangerous and should be avoided. Any steel with a Brinell hardness rating under 400 falls into this category, including standard “T-1” steel with a hardness rating in the 300 range.

LETC 007
Action Target centerfire handgun targets (like this 8″ circle) are all made of 3/8″ AR500 armor steel. Our rifle targets are made of 3/8″ AR550 armor steel.

After many years of experimenting to find the best solution, most major manufacturers of dependable, high quality steel targets now use steel with a Brinell hardness rating of at least 400. A few premium quality manufacturers use steel with a higher Brinell hardness rating of 500 or even 550. Fewer than 10 steel mills in the world can provide quality AR500/550 steel. Action Target has direct relationships with many of these suppliers which allows us to purchase steel mill direct. Steel of this quality is always certified by the plant that created it, however, at Action Target we conduct independent hardness testing on every shipment we receive. If the steel does not meet our ballistic standards, we reject the entire order and send it back.

Other steel certifications like “Magnum Steel” or “Extreme Steel” are merely marketing terms added by the manufacturer. When all the rhetoric is boiled away, there are manufacturers who use steel that is not appropriate for targets, and there are those who use steel that is. Make sure you know the difference.

PROPER DESIGN IS CRITICAL

Even the best steel can’t compensate for poorly designed targets. There are several unavoidable principles that must be followed to create targets that are as safe and durable as possible.

All Action Target steel targets are designed for predictable splatter. There are never any exposed bolts, clamps, or brackets on the shooting surface, and the target leans forward slightly to dissipate some of the bullet’s energy.

TRUTH – SMOOTH AND TOTALLY FLAT SHOOTING SURFACES ARE ESSENTIAL FOR CONSISTENT SPLATTER PATTERNS

There are two things manufacturers can do to ruin the smoothness and flatness of a steel target. First, they can use inferior steel that will crater, pock, and deform. Second, they can put brackets, clamps, or bolts in the way of the shooting surfaces. Remember, anything that can be shot will be shot. Why is this an issue? Because you can do a reasonable job of predicting and protecting against a bullet’s splatter pattern when it hits a flat, uniform surface. If the steel is damaged or if anything else is in the way, all bets are off. Bullet fragmentation and ricochet are inherent and acknowledged issues when shooting on steel targets. Proper target design helps you address those issues with the highest degree of safety possible.

TRUTH – DISSIPATING A BULLET’S ENERGY IS SAFER AND HELPS YOUR TARGETS LAST LONGER

When a bullet strikes a steel target that is completely stationary at a 90-degree angle, all the bullet’s energy goes directly to weakening that point on the steel. If the target is completely stationary but is positioned at less than a 90-degree angle, a portion of the bullet’s energy at impact is deflected rather than absorbed. If the target is positioned at slightly less than a 90-degree angle AND the target is able to move on impact, a much larger portion of the bullet’s energy is deflected rather than absorbed.

NO STEEL TARGET IS INDESTRUCTIBLE

Without exception, every steel target out there today can be damaged. Steel hardness and proper design can both be defeated by misuse and/or abuse of the target.

TRUTH – THE BASIC DESTRUCTIVE FORCE GENERATED BY BULLETS STRIKING STEEL TARGETS IS HEAT

Excessive concentrated heat alters the steel’s hardness properties and results in damage to the target’s face. The amount of heat generated is proportional to the speed of the bullet, which is why rifles cause more damage to steel targets than handguns.

TRUTH – RIFLE DISTANCE ON STEEL TARGETS IS NOT AN EXACT SCIENCE

LETC 169
Even though this target is made of AR550 armor steel, shooting too close or shooting with piercing rounds has caused severe damage to its shooting surface.

No matter what anyone tells you, shooting a steel target with a rifle – even at 100 yards – can damage your target, even if it has a Brinell hardness rating of 550. You must be very careful about your choice of steel and ammunition! Even with 550 Brinell steel and the target mounted at a significant angle, some damage is still possible, even at 100 yards. For best results, use only steel targetscart Small that are specifically designed for use with rifles.

With so many complex variables like ammunition type, rifle manufacturer, barrel length, bullet velocity and so on, it is virtually impossible to establish a set distance for shooting rifles on steel targets. To determine what works best with your specific equipment, we suggest the following: Fire a test shot from 100 yards and then examine the target. If there is no damage, move in a few yards and fire another test shot. Repeat the process until you find the optimal distance for your combination of rifle and ammunition. Some people may be comfortable with a certain amount of dimpling on the steel. Minor damage to the shooting surface will not create a shooting hazard if you are shooting at 100 yards, but if can be very dangerous if you choose to shoot at close range with a handgun on the same target. Even if your steel targets have only minimal rifle damage, they should never be used for closer distance handgun training.

TRUTH – SHOTGUN SLUG DISTANCE ON STEEL TARGETS MEANS 100 YARDS MINIMUM

Shotgun slugs have the greatest potential for bodily harm to the shooter due to the sheer volume of lead that can be returned from damaged or poorly designed steel targets. Stay back!

TRUTH – FRANGIBLE AMMUNITION REQUIRES THE SAME QUALITY STEEL AS REGULAR AMMUNITION

Many types of frangible ammunition, particularly for rifles, are lighter than regular lead ammunition. Remember that lighter bullets can mean greater speed, which means more heat, which can mean damage to your steel target. Just because frangible ammunition is designed to break up on impact doesn’t mean the distance requirements do not apply. You should follow the exact same rules with frangible ammunition as you do with any other.

TRUST THE EXPERTS

When it comes to your safety, don’t settle for the advice of your local welder. Steel targets can be fun and safe as long as they are made of quality steel and designed to produce predictable splatter. In fact, steel targets can be one of the greatest tools for firearms training, but they have to be manufactured correctly. Shooting on poorly designed targets made of inferior steel can result in severe bodily harm. Here at Action Target, your safety is our biggest concern. We have decades of experience manufacturing steel targets, and we constantly conduct ballistic research to make sure the steel we use meets our standards and your expectations. If you are looking for a steel target, trust us to point you in the right direction.

Myths About Wet Steel Traps

Posted on by Marketing Action Target

Wet Steel Trap 1As with anything else in life, the ability to make an informed decision is based on the quality of the information you receive. The purpose of this article is to explore some of the claims associated with using water on steel funnel traps.

This information represents the opinions of Action Target based on the experience and observations of our range consultants and engineers. We encourage you to conduct your own research and speak with other users about their experiences with the various bullet trap technologies presented before drawing your own conclusions.

CLAIM #1: You can use any type of ammunition on a wet steel trap.

It has been reported that frangible ammunition may cause problems with wet funnel traps because the powder created by certain types of disintegrating bullets can mix with the water and harden into a cement-like substance resulting in an extremely difficult cleaning process.

CLAIM #2: Wet steel traps eliminate lead dust on your range.

If a bullet strikes an area on a wet steel trap where the water and oil mixture is flowing (like on the bottom plates), the amount of lead dust generated at the trap on initial impact may be reduced. But if the bullet hits on the upper plates where no water is present, lead dust can be generated much the same as on a trap where no water system is in use. Also, lead dust containment systems such as water are meant to deal with lead on the bullet trap itself. They typically have little or nothing to do with emissions at the firing line or other areas of the range.

CLAIM #3: Wet steel traps capture all pullets whole and eliminate splatter and ricochet.Wet Steel Trap 7

The gently sloping angles of steel funnel plates do help prevent bullet breakup on initial impact, but bullets can also fragment into small pieces once they enter the rear chamber and strike more steel surfaces inside. Also, many designs include a vertical edge at every seam where two chambers meet and are attached to each other. Deflectors are typically used to protect these vertical edges, and bullets can fragment more significantly if they strike these deflectors. Our observations would indicate that the degree of bullet fragmentation is mostly related to the velocity of the bullet. Slower pistol rounds may be able to be captured more whole when using a primary decelerant or lubricant such as water, but faster rifle rounds tend to disintegrate whether the water is present or not.

CLAIM #4: Wet steel traps are more environmentally friendly.

A doctor’s first and fundamental responsibility is to do no harm and to not make a difficult situation worse than it already may be. The same can be said for a bullet trap. Because lead disposal is already difficult enough for most shooting ranges, the last thing we thing a bullet trap should do is to complicate the matter by mixing the lead with other substances such as water, oil, chlorine, or antifreeze.

CLAIM #5: Wet steel traps function equally well indoors and outdoors.Wet Steel Trap 9

Referring back to claim #4, it can be much more difficult to contain all potential contaminants generated by a wet steel trap on an outdoor range. Rain, snow, ice, wildlife, leaves, twigs, and other clogging debris can complicate matters when operating outdoors.

CLAIM #6: One piece welded funnel plates are better than modular funnel plates.

If everything is welded together on site, you can end up with a bullet trap that is much more difficult to service or repair should anything go wrong. Long, continuous sheets of plate steel can be more prone to stress fractures and cracking than shorter, modular plates. That is one reason why bridges and overpasses are often formed by bolting together multiple modular pieces. When modular funnel plates and joint systems are properly designed, you get a strong and maintenance-friendly bullet trap that requires no sacrifice of safety or performance.

CLAIM #7: Funnel plates mounted at a 12 or 13 degree angle function significantly better than funnel plates mounted at a 15 degree angle.Wet Steel Trap 6

If a 12 or 13 degree slope is better than a 15 degree slope, then isn’t 11 better than 12? Why not drop to 9 degrees? Or 7? Since every degree you go down can increase the cost and the front-to-back size of the trap, there is a point at which you can reach the point of diminishing returns. All other factors being equal (steel hardness, bullet trajectory, etc.), our high speed video tests do not reveal any significant difference between impacts at 12 or 15 degrees. Although it is possible to install an Action Target trap with plates mounted at either 12 or 13 degrees, we believe 15 degrees to be optimal for most uses.

CLAIM #8: A 30-inch diameter in the circular deceleration chamber is better than a 26-inch diameter.

Following the same logic, why not use a 40-inch diameter? Why not 50? Again, it is important to weigh multiple factors such as performance, cost, and space. Action Target believes that the most important thing about a chamber is that it effectively contain rounds, that it have a good service life, and that it can be easily serviced if and when the need arises. We believe our chamber design achieves these values in an optimal way.

CLAIM #9: Wet steel traps don’t require much maintenance.Wet Steel Trap 8

Regular maintenance should be expected with any bullet trap, regardless of the materials used. Just like anything else, range equipment must be properly cared for to keep it working.

The wet steel trap designs we have seen include a water pump, spray nozzle, and filter systems that should be regularly maintained. Potential debris like cardboard, paper, wood, and shotgun wads can certainly be a problem if they are introduced into these systems. Lead should be removed from the collection system and disposed of properly. And we recommend you account for any exposure the lead may have had to water, oil, chlorine, or antifreeze. Water sources should be maintained and you should deal with any potential sources of flooding or leaking. In some cases, an external settling pond or a drainage tank with a waste trap may be needed to keep contaminated water from entering the sewer system. Finally, you should consider any additional effect the potentially higher humidity may have on your ventilation system and any HEPA filters.
