What or who's have you tried so far? I have some 200 grainers cast from a RCBS mold that you can try if you have not done so already.
Had I been thinking I'd have packed some for you yesterday when we hit the range.
OK, I know what a Semi-Wad Cutter is. I've just never heard it referenced like that.
My old man had wad cutters for his Ruger Black Hawk. I only shot it a few times, but I recall that the blunt nodes bullets were supposed to be real mean on anything it hit.
