Great article Mike! Years back I shot in a metallic silhouette match put on by the South Bay Rod & Gun Club (San Diego, I was in the Navy then), I borrowed my brother's .30-06 for the shoot, I was shocked to find out I had the largest caliber on the range and I won the class! My bro was pissed that I out-shot him with his .243.
Ya know, I think ya left the .308 off the list of cases developed from the .30-06.
