I had my doubts last night, but i put a sliver tip ballistic behind the right shoulder, and the bullet came out right in front of the left shoulder. THis was the first deer i've ever seen just drop and not move. I was about an inch back from the shoulder, and still the ballistics broke the right shoulder, the exit hole was not fantastic, but I could put a quarter through it. While gutting the doe, the lungs were complete soup, the heart was fine becausei shot alittle high. I'm very happy with the 243 and i'm happy to say it's my new deer gun.
