I did some looking around and it seems that the Deep Curl is the same bullet that Federal Fusion uses except the DC has a flat base instead of boat tailed. It is also a plated bullet. Federal has always marketed the fusion as a "deer bullet". I would think it would do the job on an elk but as Bigcountry pointed out, there are better out there. They are said to be very accurate.
If my local Sportsman's ever carries any, I'll probably pick up a box to try them. It's not scientific or the same as shooting into an animal but I like to shoot into dirt at 100 yards to see what it does to the bullet and how the bullet holds up.
Good luck!
Edit: Also read in several places that Speer is doing away with the Hot Core line and replacing it with the DC line. They must have confidence in the DC line.
