Old powder questions - Hercules in metal cans
« on: November 28, 2023, 11:42:09 AM »
I recently purchased an entire reloading set up from a friend’s father’s estate. My friend did some reloading around 2010, but hasn’t done any since, and is spending his resources on other hobbies.

In this purchase, there were two old cans of powder. Hercules bullseye, and Hercules unique.  They are metal cans.

Besides the following, would there be anything else you would recommend to do to test the powder for viability of use?

1, smells like new powder.
2, leaves no discoloration on a white piece of tissue paper.
3, a small pile seems to burn just like new powder.
4, the metal cans are in perfect shape, no rust inside or outside.
5, load a minimum charge and see how it compares on a chronograph to new powder.

There is probably 2 to 2 1/2 pounds of powder total in these cans. They have been open and none are full.

I am having fun going through the boxes and seeing all what is there. There are definitely duplicates of some of the stuff I have already, so I will eventually be putting that stuff in the for sale section here. There are some names of equipment I’ve never heard of, and I need to do some research. In other words, ask questions here, and Google.

Thanks in advance for all the help!

If it goes "boom" or "vroom" I'm intersted.

If powder has been stored properly (cool and dry) it last about forever. Some of the original batch of Bullseye powder from the turn of the century (1900) use to be tested regularly by Lyman to see if it had deteriorated. Last I heard it hadn't. Also, people collect the cans and will pay for them if in good condition.

I still have IMR powders and Winchester powders in metal cans.  Last used some of it 7 or 8 years ago (when it was 30 plus years old.  Zero issues.  Just re proved that IMR4895 gave us the best groups in the M1A type riles with 150 grain bullets.

If it passes the tests, use it up.  It'll make good ammo.
I just keep wasting time and money on other brands trying to find/make one shoot like my P07 and P09.  What is wrong with me?

Thank you for the confirmations of using it. Appreciate it.

Never knew that about Lyman testing old bullseye powder.  Very interesting.

It will be fairly obvious when the powder deteriorates. The nitric acid comes out of suspension and....
• Has a sharp, acrid odor
• The acid may attack the canister, causing corrosion or eating holes in metal cans
• The powder will start to loose it's black, graphite color
• There will be evidence of a reddish-brown "bloom" or slow chemical reaction taking place on the surface

Powder that has been stored properly (cool, dry place & in proper anti-static containers) will last almost indefinitely.
