It's listed in my 10th Edition Cartridges of the World. If I could. I'd photo the listing and post it. My pics are too big on here.
It shows a 125gr sp loaded with IMR4227 23.0grs for 2205fps.
2400, and Norma 200 are the other powders listed. Bullet weights from 100 to 150grs.
72' & 73' appear to be the year of initial use. Should be reputable verifiable data in the archives somewhere.
