I have some old DuPont labeled powders, one unopened of IMR 4320. Are they all good to use as long as they don't smell or appear rusty?

Should be! memtb
Thx.
So what's the best use for the 4320? It's obsolete now, but I guess used to be utilized in 270 Win or 30-06. I have my Dad's guns. He told me his Model 70 Super Grade( 1948) would !all be in a dime @ 100 yds. I never saw him do it BTW. But he was a much better shot than I.

If you have some old reloading books…..there should be some data on it! Good Luck! memtb

I have a 222 mag and a 17 rem that loves stuff.
I'll try to see I can find some.
Speer Reloading Manual Number 10 has loads using all of them.

I had some that was over 20 years old and when I opened the metal can it smelled good so I tried it in my 243 and it shot just fine

36.1 grains of imr 4320 behind a sierra 85gr bthp accounted for more than a few mule deer bucks and cow elk in my kids youth, shots stayed under 300 yards. I have a 1lb'r full of the stuff and 300 bullets to keep it relevant while I'm still hanging around. I thought it was good enough not to try anything else
Here is an article on Accurate Shooter about IMR4320
I still use it, does that mean I'm obsolete as well? I use it in 270win along with 4350. Occasionally I use it in 264wm, but so far use 4831. All of these are in the imr collection.
ARLife4me you are NOT obsolete!
I may be as at 70 I've come to realize I have more yesterdays than tomorrows.
You have a long life ahead still! I'm 57 and live in a life of pain with little hope of reducing it. Over 12 years this way and getting worse.
With 243win and 260rem in my collection those imr's will be put to use.
