Glad you have it and HOPE is is a straight 7x57 and not AI messed up.
Just so you know that your statement is BS. They don't call it Ackley IMPROVED because it is inferior to the 7X57mm. And "messed up" is your way of thinking.
Well, some guys just seem to get touchy about the AIs - touchy enough to characterize another guy's thought process even if they don't know about it. I hope that your comments were in jest.
Whether or not you understood what I intended, and just in case you are serious with your statements, you seem fairly quick on the BS trigger. I said nothing about inferiority or superiority. No matter what "they" say, the term "improved" yields no result one way or the other - it is a label used by the designer.
Somewhere back there I managed to grasp the theory and design principles associated with the AI. Did you ever have a quiet personal conversation with Ackley on the subject of his various "improvements"? There is more than one way to mess up a finely made rifle.
