I know I have a couple empty #1 jugs. PM an address and I should be able to get the lids out first of the week. How many do you need?

$100 worth of powder bought 3-4 years ago was probably only a pound or two.

Look what up? I've used 4227, since 1985. I've had very can that it came in, since it was Dupont 4227. The can I pictured, I won in Spokane, at least 4 years ago. 

Hodgdon changed IMR 4227, to H4227, about that time but, kept the IMR name on it. That's what started this thread. IMR 4227, is different than H4227 but, H4227 is all that they market but, under the IMR name.

It's easy to tell, if the can says made in Canada, it's IMR 4227. If the can says that it's made in Australia, it's H4227.

I buy all my 4227, at gun shows now but make sure of where it was made.

And another thread ridden off the rails and crapped in by folks who can't figure out why membership doesn't grow and new people won't go to shoots to meet the sour faces behind the keyboards. 

Years ago I transported bore cleaning solvent in the same container I had a sleeve of primers. A week later I separated them and most of the primers were duds. Learned my lesson on solvents and shooting supplies. I am sure storing cleaners with the powder is doing you no favors. My thoughts.

I was trying to be polite with the sour face comment.

Sir, 
if you think for a second, that your time and knowledge presented on this forum is not overlooked at times because of the way you present yourself, your a damn fool.

There are a select few, that seem to look for ways to poke each other in any threads they end up in together. Honestly it gets in the way of people who would like to learn and carry on the traditions.

Keep it in off topic, where it seems a whole section was created for no other reason than to give the spoiled children a place to play. Where poor behavior is tolerated, where instigators are more than welcome to stand in a circle and blame the other guy for breathing their air.

Many days there is just to much crap to sift through around here to want to try to participate. Take a good honest look at your posts and tell me again it's the always other guy.

Linda,
Looking at those cans with fine reddish rust on the EXTERIOR of the caps and Unpainted tops of the old square cans shows that for sure its an environment/fumes/???
around the cans that is causing the rust.
Could be an acidic cleaner for example. 
As has been said, if there is no acidic smell, and no red
dust inside the cans with the powder, and you can still smell
acetone /solvent odor, the powder is likely not deteriorating

A year or 2 or 5 ago I read about problems with chinese sheet rock corroding plumbing etc. Any chance that might be the problem?
