s when shooting at steel targets are minimal. The materials of which both the target and bullets are constructed should be chosen to cause the bullets to pulverize on impact, and therefore hardened steel targets and regular lead core bullets or copper jacketed bullets should be used. Unhardened steel should be avoided for use in targets, and ammunition with armor-piercing properties (i.e. steel cores) should also be avoided.
Furthermore, it is important always to shoot steel targets at an angle in both vertical and horizontal direction so any ricochet immediately strikes the ground away from the shooter. This angling of the target also reduces distortion of the steel target and prolongs its lifetime. Localized heating, causing loss of hardness, is also reduced. Additionally, not mounting the targets solidly but allowing swinging or moving when shot reduces stress on impact. However, it has a downside in that shooters should only shoot at targets that are not moving to avoid accidentally reducing the angle of impact and thus possibly causing ricochets.
Target material
As a safety precaution, steel targets must be made out of hardened steel, which is more resistant to
plastic deformation

If the deformation is negligible, the object is said to be ''rigid''.

than regular, soft steel. For steel targets, the steel should have a
Brinell value of 500 or slightly more. One American producer of steel targets claims to use only steel with a hardness greater than 500, most often between 515 and 540. They also claim that the steel gets too brittle if higher Brinell values are used.
[Shooters Element](_blank)
Hardened steel is available in different Brinell values or thicknesses, and stainless variants are also available. A common trademark in the United States for hardened steel is AR500.
Regular steel is too soft, resulting in bullets either punching through the target or making a crater whereupon subsequent bullets may bounce back toward the shooter or spectators, often with great force. Even thick plates quickly get holes and craters if they are made of regular steel.
Processing of the steel target
Many workshops have the tools to manufacture steel targets out of hardened steel, but it is important that it be done correctly. For instance, water jet cutters or laser cutters are preferred, but plasma cutters can be used. In contrast,

damages the hardening. Hardened drill bits with floods of cooling medium, laser or water jets are needed to cut holes in hardened steel targets.
Thickness and distance to the target
The required thickness of the target depends on the distance intended for shooting, steel quality, caliber, bullet type, and bullet speed. High velocity rounds more easily penetrate steel targets, meaning that faster bullets even of relatively small calibers or diameter are more likely to punch through a target.
Manufacturers recommends at least 1/4" thickness (6.35 mm) with 500 Brinell value for pistol shooting with common calibres such as

Bullet choice
Lead core or
frangible bullets are preferred, since they are pulverized upon high-velocity impact, and the dust will then be spread out to the sides of the target. However, bullets with hard cores (like steel, or "bi-metal") are not pulverized and can either penetrate or ricochet, causing them to be potentially dangerous.

Practical shooting
In practical shooting, administered by IPSC, both cardboard and steel targets are used. Standardized steel targets, called "poppers", are often used, but other forms and shapes can be used as long as they comply with the rules. The smallest sizes for respectively circular and square targets, both for rifle and pistols, are 15 cm Ø/ 15x15 cm, while the largest targets allowed for pistols are 30 cm Ø/ 30x30 cm and for rifles 30 cm Ø/ 45x30 cm.
