An Australian gentleman on another forum I frequent has come into a “vintage” 8 pound (factory sealed) metal tin of Winchester 1500HS powder.
Does anyone have any experience with this powder?
Does it have a modern equivalent, or could it be an older non canister powder that was sold off as bulk surplus?
Is there any data out there and is it suitable for handgun ammunition?
He’d sure appreciate any help he could get as it appears that the Australian powder shortage is way worse than ours.
Thanks
Dr.
