In firearm safety, what does H in A CHUM SPORT signify?

The correct choice, which stands for "Hard surfaces should be avoided for shooting," emphasizes the importance of safe firearm handling practices. When shooting, using stable and appropriate surfaces contributes to maintaining control over the firearm, ensuring it doesn't accidentally discharge or cause harm to bystanders. This principle encourages awareness of one's shooting environment and advocates for responsible behavior, minimizing risks associated with improper shooting positions.
