Schneidas,

The OLP and USACG shapes are pretty darn similar. I couldn't say exactly how close, but they're close. A big part of the problem in comparing them is indeed the nut width. Ernie Ball uses a 1 5/8" nut width, which I personally dislike. Therefore, it would be hard for me to claim that they're "the same." Besides, I believe there are slight variations from year to year as well as between the MusicMan and Peavey Wolfgang profiles. They're more alike than not, however.
