See my original post: Nosler solid base. 55 grain, which I didn't say before. I don't think there was a better bullet available at the time.

The 55 solid base worked great for me. I've got a 172 lb. dressed 8 point hanging on the wall that fell to one of those through the lungs. Range 125 yards, quartering away, bang, flop. Bullet hit at last rib on left side and was recovered, well mushroomed under the hide near the right shoulder.
