Talk to me folks. Teach me. Why is hunting a deer with a "full metal jacket" either against the law, or not wise? Is that why there are Poly tips on my rounds; to satisfy that regulation, but also keep a jacket (even if it only covers a percentage of the bullet) around the Lead to keep less Lead deposit in the rifling grooves?
A full metal jacket bullet is a bullet that is completely encased in a jacket. There is no exposed lead or hollowpoint. When it hits the deer it will not normally expand and will not do as much damage as an expanding bullet. Therefore less likely to make a clean kill. This is why the Geneva convention specifies full metal jacket bullets for war. They will not do as much damage when they hit a person.
(Luke 11:21 KJV) When a strong man armed keepeth his palace, his goods are in peace:
(Luke 22:36 KJV) Then said he unto them, But now, he that hath a purse, let him take it, and likewise his scrip: and he that hath no sword, let him sell his garment, and buy one.
