Jeff,

A more accurate comparison between the .30-06 and .300 WSM would be with the 180- and 200-grain AccuBonds, since in the same length barrel these can be given about the same muzzle velocity. I know this because I've loaded for both rounds a lot.

The actual G1 BC's of the 180 and 200 Ab's, according to Bryan Litz, are .481 and .524. Let's start each at 2850 fps, which in my experience is a sane max for both rounds.

According to Bryan's program, at 700 yards the 200-grain drifts about 4 inches less in a 10-mph crosswind. Please explain how this would make a vast difference in "hittability."

The 180 would also be going 83 fps slower. Please explain how this would cause the 180 to fail to penetrate.
