Which of the following bullets is illegal for big game hunting in most states?

Full metal jacket bullets are typically considered illegal for big game hunting in many states because they are designed primarily for military and law enforcement applications, focusing on penetration rather than expansion. When hunting big game, it is vital for the bullet to expand upon impact to cause sufficient tissue damage and ensure a humane kill.

Unlike hollowpoint bullets, which are designed to expand on impact and create a larger wound channel, or roundnose lead, which can be effective provided they expand properly, full metal jacket bullets often retain their shape and do not expand. This can lead to less effective kills and a higher likelihood of the animal being wounded and escaping. Additionally, some states have specific regulations governing ammunition types, especially to promote ethical hunting practices and animal welfare, hence making the use of full metal jacket bullets mainly unsuitable for this purpose.

The mention of 'protected tip' is somewhat vague, but generally refers to bullets designed with a tip that can protect the projectile during flight but may still expand upon impact, depending on the construction. Therefore, this would not be categorized as illegal for hunting, unlike full metal jacket bullets.
