Magnum AI??

[kc]

It may sound a bit strange but have you ever heard of an Acly Improved in a Magnum cartridge? such as a 7MM MagAI or a .300MagAI.

a 338 Sin is a very improved 330 Dakota, but there are others out there, mostly changing the shoulder angle.

It's done all the time. Just not named AI. Usually with the suffix of Improved or Imp after the caliber designation.
