The original intent of the Bill of Rights was to guarantee the safeguard of liberty and prevent oppression of the people. Therefore people have to be armed with the weapons used by the military. This amendment was not intended for hunting, although that is allowed. It is intended for self-defense collectively from federal govt and for personal self defense.
“Experience should teach us to be most on our guard to protect liberty when the Government’s purposes are beneficent. Men born to freedom are naturally alert to repel invasion of their liberty by evil-minded rulers. The greatest dangers to liberty lurk in insidious encroachment by men of zeal, well-meaning but without understanding.” — James Madison
