Here's one review/post for someone who uses the same bullet i'm using for elk.
The Platinum 338gr, is the most accurate, hard hitting bullet for Bear and Elk I have ever shot. They shot 1/2" groups at 100yds. with open sights in My Thompson center Encore. I have killed several Elk and Bears with this bullet. Drops them in their tracks every time with a well placed shot. A little pricey for 15 rounds, but worth the price for what they do.
