Well just another example of placing a bullet, doesn't matter what size in into the boiler room of an animal does what it is supposed to do, wreak havoc with the organs that sustain life. A .22 long rifle could have done the same thing given a reasonable range and shot. Bullets kill by disrupting the function of major organs, doesn't matter if that happened with a .22 long rifle (which many poachers can attest to) or .458 Winchester magnum. The only difference is how much of the target animal is desecrated by the impact of the bullet. Here in Wisconsin it is verbotten to shoot at any game with either FMJ or Match hollow points. If a warden had checked and found that you had shot the deer with an illegal bullet you could have lost the deer, your rifle and anything else connected with your illegal hunt to include your car or truck that transported you to your field destination. Your ability to hunt for many years could have been taken away with the same speed your bullet traveled to the target . While I congratulate you for your harvest, I also chastise you for shooting illegally . Good hunting ammo costs somewhere between $30 an $70 these days. Cheap compared to what it could have cost you. Also keep in mind that your words here stating that you most likely broke the law where you were hunting can come back and bite you in your behind when a warden or police officer reads it. All for the want of a good hunting bullet.
