Have never heard of that one. It's probably not a cannister powder, but a factory lot code or a rebrand, such as Higginson (Ammomart) used to do.
Could it be PB?
If so, it might be Expro (the Canadian powder maker) PB. It was sold as IMR PB. A bulky medium speed powder.
What caliber is the ammo?
If it is 38SPl, for example, I would try it in a 357Mag.
