Was givin 3 #1 pounds cans of "OLD" IMR-4227. Seal has not been broken.The cans are Baby Blue and one Dark blue? Not sure how old, but they got tobe at least 20+yrs old.
I've only used IMR-4227 to load 218bee.Anybody use it to load pistol Cal.

44 Magnum, 357 Magnum, and such.

Also good for .32 WCF.

Some reduced loads in bigger rifles.

Were they made by DuPont or IMR, Inc.?

Smell them to make sure its still good. Good smell is solvent. Bad is acidic, like vinegar.

Pour some into a dish and look for a reddish dust. If you found none, its still good.

If these are the metal cans (I'm sure they are), it will keep much longer than 20 years.

If you don't want it, I will buy it from you. I had about 1/4 can left and accidently poured some WW 680 into it. I'm thinking of sifting but havent found good screens. 4227 is some fine IMR, both in grain size and application. Its cherry for my Hornet. .75" groups at 100 yards with full power, compressed loads.

Well, you know it is at least 13 years old. I think it was in 1988 that DuPont sold all powder manufacturing to IMR.

I have used 4227 in some .44 Mag loads and it works very well, but it takes (a lot) more of it to get a good velocity than some other powders with faster burn rates. And it definitely needs a long barrel to get the best use out of it. It's probably better for use in a carbine than in a revolver.

240 gr. JHP; 22.5 gr. IMR 4227 = approx. 1300 fps. out of a 7" SRH.

The main reason I don't use it very much is that it has an unusual sickly sweet smell when fired. To me, the smell is annoying because I usually like the smell of burned gunpowder.
