I'm looking for some load data for my father. He got a bunch of Winchester 63 grain PSPs, but we can't find load data in any of his manuals.

I've tried a a few different Google searches and no dice, and nothing here.

Can any of you point me to a manual or PDF that has load data for that projectile? He's got a few different powders at home and we can pretty easily find various powders locally. Just no data with that projectile thus far.
