Rumour- New Powders have 10 year shelf life?

[clearwater]

Read it on the Nosler reloading forum. The latest greatest powders have limited shelf life.

Sounds like the new "green" temp in-sensitive powders?

Anybody heard about this?

[John Boy]

Have a link to the thread? Did an Internet search = Nothing about 10yrs

[clearwater]

"They're doing that for 2 reasons...
1- Most of the powders we consumers get are formulas that failed government contract testing....Uncle Sam wants temp stable powders with a long shelf life.

Many of these new powders only have a 10 year shelf life.

2- Most consumers want temp stable powders.

"Most of the powders we consumers get are formulas that failed government contract testing....Uncle Sam wants temp stable powders with a long shelf life." - This is not true.

There is nothing I can think of in my limited knowledge of smokeless powder that you can make them decompose at a certain date.

[Hamish]

this particular rumor has gone around for decades. how would they make it self destructive/useless?

[labradigger1]

Nonsense. Imagine the litigation when the squibs would occur.

[dtknowles]

If you get a squib because you have reloads that are more than 10 years old, who you going to call?

One change with some of the new powders is the chemicals and methods for neutralizing the acid used in the nitrating process. In an effort to reduce hazardous waste (avoid cost) they changed the process. Will that affect shelf life, we will not know until the powders processed that way sit on the shelf for a while.

I'm still using Bullseye I bought at Camp Perry in 1967.

The military and police require shelf-stable powder and ammo.

There is no good reason for the powder companies to do anything else.

Gunshop rumor BS.

[dragon813gt]

Remember during the Clinton era that primers were going to change so they had a short shelf life? That obviously didn't happen.

Let's say this rumor is true. The powder companies owe it to their customers to tell them this information. It's not like it's just going to stop working at the ten year mark. There will be a degradation as it ages. This sounds dangerous to me.

One word........lawyers. They have to cover there keisters.

Same thing with medicines and canned foods. All have a "best by" date. Total BS. As long as things are stored in an environment "where you would live comfortably", all will be OK.

[JSnover]

I'm not buying the factory seconds rumor without reliable sources. The implication is that they've tried hundreds of formulas and only came up with a handful that were good enough. Really? Is it that tough to figure it out after more than a century of research and development? Powders that were made before many of us were born are still burning correctly.

Sounds like "Mission Impossible" to me ............. "in 20 seconds, this tape will self destruct" .......

Early 70's we were still eating surplus C-Rations left over from the mid 60's at hunting camp.

[Hickory]

Until I see proof, it is a rumor.

[toallmy]

Someone will have to keep a can of new powder for 10-20 years to find out , l am planning on burning my powder before that , and the primers as well . But I would not put it past our currant government to try it .

Man has always strived to preserve stuff.

Early on, he discoved how to make cheese out of milk to allow it to last much longer.

Grain easily turned into alcohol for longevity. (And fun!)

Salt curing of meats preserved them for long periods of time.

Then canning in glass containers allowed people to enjoy summer foods year round.

Then came the innovation of "tin" cans and the world shrank! Foods from all over the world were now avaialble to most at reaonable prices and had long shelf lives.

Now we vacuum seal, irradiate, and freeze-dry tons of food stuffs.

But I really cannot imagine any of us keeping gun powder around for 10+ years to see if it still works!

We just shoot too much!!!!!!

WHAT IS THE SHELF LIFE OF AMMO AND STORAGE?

Store reloading components and ammunition in a cool, dry place, protected from direct exposure to sunlight. If stored properly there is a 10-year shelf life on loaded ammunition.

Thank You!!
Heat and temperature variations will deteriorate powder.

If you read the data there is a proposal to do something with medium arms that includes a powder that might break down after x # of years. IIRC, small arms in the military are hand held and medium are vehicle based, nothing to do with sporting powders.
