And .280 AI advocates get kooky about differences that amount to a few thousandths of an inch, and a few fps or grains of bullet weight.

These all may make some difference at XYZ angle, or past 500 yards. Maybe. But the longer I hunt the less difference I see in the results from ANY cartridge, within broad parameters at normal hunting ranges. Properly applied, they all kill stuff.
