I don't like the old silvertips because of one bad experience. Many years ago I shot a big midwestern buck at 100 yards with a 30-30 and silvertips. Hit him almost perfect but a little far back. I could see I hit him, found a lot of blood at the scene. As I began trailing the blood became less and less and I found two flat pieces of bone. Eventually the blood stopped altogether. It got dark and I had to stop. I felt terrible leaving a wounded animal. I went back the next day at first light and jumped the buck about 200 yards from where I lost him. He was running on three legs, I dropped him with a spine shot. When I skinned him I found out the first shot had hit the first rib and fragmented (remember the flat pieces of bone). Another piece of bone slid down and covered the entry wound. The largest piece of the bullet traveled forward, went down the left front leg and broke it. The other bullet pieces did little damage. I think the old silvertips have too much lead exposed for bone hits. Of course the more poweful 270 might help the problem. I have used a 270 win since that experience and really like the Hornady light mags.
Sorry for the long story, by the way that buck dressed out at 200+. On a bear go for the light mags.
