A buddy of mine had a part can of Hi-Skor that he bought just for the can, 4 lb. square cannister with the big snap on lid on top. Had 1# 12oz of usable powder in it. Inside of the can is perfect, no bad smell to the powder. What's not to like?
Took a while to find data for Hi-Skor, considering it was discontinued in 1965 as best as I can tell. Finally found a link to a thread that brought me back here and there was a scan of an old data sheet. It looks like between B'eye & Unique for charge weights and usable in light/moderate loads in 38/357, 44sp and 45ACP. There's a bunch of loading in that 28 oz worth.
BTW, please , nobody tell me it HAS to be Hi-Skor 700X or 800X. There were other threads where some true experts got all nasty about that. I guess if it only happened before you were born it never existed.
