A tabular representation of suitable thicknesses for steel targets, correlated with factors like firearm caliber and projectile velocity, provides crucial information for safe and effective target practice. For example, such a reference might indicate that a .22LR cartridge requires a thinner steel target than a .308 Winchester. This ensures the target’s structural integrity while preventing dangerous ricochets or projectile penetration.
Choosing appropriate target dimensions based on anticipated projectile impact is fundamental for safety and maximizing target lifespan. Historically, target selection often relied on anecdotal experience, leading to inconsistent results and potential hazards. Modern resources offer detailed guidelines, contributing significantly to safer shooting practices and a more predictable shooting experience. Appropriate thickness selection also prevents premature target wear, optimizing their usability.
