Re: Powder shelf life?

I have about a dozen metal cans of IMR7828 that is about as old as 7828 can be. I've had it for about 25 years and it is still good.

Thanks guys that is kinda what I thought but I didn't want to take a chance and add another variable when trying to determine my best load for my rifle.

Re: Powder shelf life?

I recently reworked nearly 200 rounds of reloaded M855 ammo I bought at a Dallas gun show 20 years. ago. Each round had numerous problems, at least 3 problems each and a few rounds as many as 5 problems. Several of them had wet clumped gunpowder in them where the reloader did not properly dry his cases thoroughly. I blended all the powder together and let it sit for a while. I backed off the loads by .3 grains and reloaded. It was some of the most accurate M855 that I have tested so far. Now, if you haven't let the powder sit in a wet case for the past 20 years, it should be no worse for wear than mine was.

Guys have thrown smokeless powder in water overnight, dried it out and reloaded it and it shot just fine. Don't try this with blackpowder. Smokeless powder is supposed to have a 30-50% moisture content. Drying it completely out with dessicant would be a mistake, and that's probably one reason that rounds that have set around in the hot sun for a long time develop dangerous pressures.

Re: Powder shelf life?

A sign of the times, if one good thing comes out of this supply vs demand maybe us shooting up all the powder in cans we loaded a dozen rounds from and got lured away to something different. I was in the basement looking at suitable powders for my .223. I figured which ones and how much, and then discovered I can't find my 223 die? I guess I can't blame that on the knuckle head storing his golf clubs at 1600 Pennsylvania.
