Please move this thread if it's in the wrong area.
I came across 2000 CCI small pistol primers and some Unique in the back of my shop.
They will have been exposed to temps ranging from 10 to 110 degrees over the last 13 years.
I would like to use them up with a light load of 158 SWC and 5.5 gr. of the Unique in .357 brass in a Python if safe.
Anybody's ideas are welcome here. Thanks.
