How long does powder last in storage? I am sure it all depends but I have som 748 that has been stored in its original container. the jugs are about 1/2 full each.

Would that last say 10 years?

Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.



What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

Yes, unless it's stored in a hot place. Keep it cool and it'll last way longer than you will.

My (unfortunately rapidly dwindling) supply of Surplus 4831 is now over 60 years old and has been stored without much regard to temperture or humidity, and mostly in the cardboard kegs it was purchased in. It is still one of the most consistent powders I shoot.

Mine is now gone but I know it was over 50 when it ran out. Sure wish I could have looked forward and bought more of that $1/lb powder when I had the chance.


As usual just my $.02

Storage of powder in proper containers ( Not sure cardboard even waxed cardboard is a good container ! ) That have a moisture resistant outer coating or metal cans are proper storage.

The real trick is in delaying deterioration , to minimize the air volume in the containers when removing powder from them .

Kind of like saving old paint . Say you used a half gallon of that good paint or lacquer or what ever . Now you don't want to throw it out nor do you want it to go bad in the can . Drop glass spheres , marbles even shot glasses material refills the can volume displaces air. Replace the lid GOOD TO GO .

Shoot straight Know Your Target . ... salute
