Hello Len, From what I've read, you have 1-3 rifles set up in 7mm Dakota. Please tell us a little about your cartridge choice, brass quality and real world velocities (compared to 7mmSTW or RUM). Finally, why the 7mm Dakota vs. the .300 Dakota? I also read that it is possible to form Dakota brass from Ultra mag. cases by using a redding case forming die in .404J. Is this doable? Big Thanks!
