I amazes me how old powder retains sits energy.
I was gifted an old can of Hercules Herco.
It came in the tall cardboard can.
The price tag said $5.69.
I have no idea how old this powder is.
In the lot was also a square metal in of Herco.
I don`t know which can is older.
I was skeptical about this powder so I loaded 10 rounds using it for the 357.
The load was 6 gr Herco under a 160 gr cast bullet.
It was a nasty day so I just took them out and shot them at a can to check function.
The powder burned like it was new.
I will chronograph them when the weather improves.
