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.
