And..................this is where the fight started! Anything that the .280 Ackley Improved can do the .270 Ackley Improved can do or better!!! It may not be as popular because it hasn't caught on due to some 1950's bad press and old powders. .007 thousandths of an inch does not make that much difference when it comes to deciding which round is most effective for calibers. Wait a couple of years, some ammunition manufacturer, who has run out of new ammunition to manufacture, will check the market to find what has not been lauded, boasted and what IS dreamed about. Then the cartridge will receive an incredible marketing campaign, written up in every possible hunting and shooting magazine as the latest laser round in the world, that will drop and elephant at 1000 yards, and it will become the latest/greatest round of the 21st century, the .270 Ackley Improved Creedmore!! Please don't get me wrong the .280 Ackley Improved is an impressive round by all counts, however the .270 Ackley Improved is a round has gotten an undeserved bad rap for many years. My intention is not to bash any cartridge, it's just that the .270AI does not get the recognition it deserves.
