The sst isn't the best choice for Elk. Widener's is selling an excellent Elk bullet at a clear-out price. Here is a link to the
300g Nosler Partition. It is a premium bullet at a near common bullet price. They are accurate in my rifles, and they are a proven Elk killer. You may be able to use the Nosler bullets in the red sabot from the sst too.
Hoping you have a great hunting season!
