Dreams involving violence and weaponry can often reflect inner turmoil, feelings of vulnerability, or a struggle for control in your waking life. In your dream, the act of house hunting could symbolize a search for stability or a sense of belonging, while the use of an old busted rifle may indicate feelings of inadequacy or being ill-prepared to face challenges.

Shooting two people could represent a desire to eliminate certain aspects of your life or emotions that you find threatening. However, being shot in return suggests that these actions may have consequences, and it may reflect feelings of guilt or fear of retaliation in your waking life.

The search for a better gun symbolizes a desire for more power or effective tools to deal with your struggles. However, not achieving your goal (finding a more effective weapon) and then facing injury indicates a sense of failure or helplessness.

The punch knife that doesn't break skin could represent a struggle to assert yourself or defend your boundaries effectively. It might suggest that while you have the means to fight back, you feel that your efforts are not having the desired impact.

Overall, this dream may encourage you to reflect on areas in your life where you feel under-equipped or threatened, and consider healthier ways to address your feelings of vulnerability or conflict. It might be beneficial to explore these emotions further and seek constructive solutions or support in your waking life.
