Actually, it was the Stateside Rifle Ranges.
Most were designed for .30 ball (1906).
The M1 174 gr. boat-tail round was capable of exceeding the designed safety limits of these ranges.
And, since the long range machine-gun barrage had been abandoned as a tactic, they requested a replacement round that mimicked the .30 ball (1906).
What they got was the M2 ball/AP.
