Has anyone shot a Hyrda Conical? Have you killed anything with one and how did it do? I saw some hand cast a few days ago and they had 515gr and 600gr for the 54cal. I think the 600gr would be too heavy. I was just curious because I know that differeny company's make them. For now I am sticking with the 425gr Great Plains and 435gr Buffalo but I was just wondering how these work for you guys.
