Thread: Does this powder have other names?

We acquired some powders from a relative and I’m just sussing out 1 container which I can’t find online. Pretty sure I’ve managed to add a photo. It’s just got a sticker on front stating highland 180 gr 303 powder. On the back is a legitimate looking adi sticker. Yes it was acquired along with a 303, so could well use it for reloading but I want to know more about it first
