I'm using the same bullet for my bear loads. I have mine loaded up with Rel. 7 pushing in the 1800's fps. out of a Guide gun. I haven't had the opportunity to shoot anything yet. I tried to but, it just didn't work out. I'm going to try another bear hunt this fall to see how theses bullets work. From what I have read these bullets are suppose to be great on game animals. I don't see why they wouldn't be.
