I've only used a Silvertip 1 time. It was a 150 gr in a 270. I don't know if this was the fault of the bullet or just bad luck. A 3x3 deer was angling toward me. I shot at about 60 or 70 yds at the point of the shoulder which was in a direct line with the heart. The bullet didn't enter. It went under the hide, slid sideways, and slid the full length of the rib cage between the hide and the bones. It didn't enter until just in front of the last rib and you know what's behind that. It was pretty messy. He ran nearly 200 yds before he crumpled. He was dead when I got to him. I didn't find the bullet to see what happened.
On the chance that it was the bullet, I've never bothered to use them since. Also, this was the only big game animal I've shot with a factory round since I was in college in the 60's.
