Howdy at the fire. While our experience with TSX are limited to the 300 gr. I can't say enough about them, both on plain game and 2 Cape Buffalo and a Lioness. They are accurate and expand perfectly, I mean perfect. My wife also took a Blesbuck at 317 yards with her .375 H&H. I higher recommend them. Patrick
