I've got H4831 that's over 30 years old and it still shoots very nicely thank you. Keep it cool and dry and keep shooting, or send it to me..... :-}

Re: shelf life
I would check for discoloration or odors for powders 20 or so years or older.
I have had a can of extruded powder that contained rust colored dust when opened - this is a sign of deteriation.
Storage conditions are the biggest factor in powder life.
Your storage conditions are ideal.

Re: shelf life
I've got Cordite powder that is 85 years old that shoots just fine.
I bought several pounds of Hotchkiss Glass Plate Flake from the 1930's that is as good as the day it was made.
As stated above as long as the powder does not have an acrid Oder to it, it should be good. Over the years I've been reloading I have only found WWII Italian powder to be questionable/dangerous.
Also the recent .50BMG demilled powder has been a real problem with corrosive gasses that can bee seen rising from the powder!
But, normaly, if the powder has been stored in a dry ,cool place it should be OK to use.

Re: shelf life
For teh last 4 years or so, I've been using some pistol and rifle powder that was manufactured in the 1950s...it runs fine, a touch slower than just bought powder, but I sort of expected that.
