If I had to chose a bullet for under 300 yard work, it would be the Swift A Frames. They are better than old Nosler parts for both penetration and retained bullet weight and that is saying alot for elk.

Serious bullet penetration testing done on dead elephants. So the penetration numbers are for real, not on newspaper and boards. Bullet make and style regardless of caliber should perform the same regardless of caliber. Notice retained weight and penetration for Swift A-Frames.
