I use it in my Winchester 32-20 with lead bullets.

Back in the day I loaded 22.0 behind a 240 Hornady FMJ.
Would really slam the rams at 200 meters.

4227 is the very best powder i have ever used in 44sp. and 45lc i have used it for years. when useing it use a mag. primer or it will not all burn. my load with 45lc is a 255 cast and 19gr. 44sp. is 17gr with a lyman 215 cast.
Good velocities, great accuracy, can't get enough in the case to create an overload, and it's single-based (which is what contributes to it being easier on the barrel than other powders in this burning rate range), makes it a fantastic powder for the 44 Magnum.
It works great in the other applications listed. If someone doesn't have good success with it, they haven't tried enough variations. It does like to be at 100% load density or mildly compressed.
I will say that since Hodgdon took over IMR and 4227 is now being manufactured in Australia, I'm not sure it's a single-based powder anymore. I have enough of a stash of Canadian 4227 that I just haven't bothered to look...

I'm late to this post, but 4227 is the cat's meow in the 500 S&W Magnum. Its burn rate fits the caliber to a Tee.

Seems like imr4227 and h110 are still on the shelf at a local gun shop. Saw a user contribution on a site using 10gr of imr4227 in a 40s&w with a heavy bullet. Anyone ever try this?

IMR4227 was the first powder I ever handloaded with. The Lee Loader kit had a dipper for it. Worked perfectly with the 44 Magnum and 240/250 gr jacketed and cast bullets.
IMR4227 was designed for the pistol sized rifle cartridges like the 44 WCF, 38 WCF and 32 WCF. Burns very clean in rifle length barrels. It does leave some unburned powder in revolvers. IME, it leads much less with cast bullets and is very mild on guns in comparison with other magnum powders. It also has very light flash.
I have managed to find good loads with it in 357 Magnum, 41 Magnum, 44 Special and 44 Magnum. If IMR4227 was the only revolver powder I could get, it wouldnt bother me too much.

.30 M1 Carbine and .50AE are the two I use it for.

As others have said, it's the bee's knees for the largest revolver cartridges.
I use it in the 445 Supermag and 444 Marlin with a WLR primer.
I suspect it is available because of it's narrow range of applications.
It would be nice to know authoritatively if the IMR and H versions are the exact same thing these days.
Many manuals have different recipes for the 2 and QuickLoad has different properties for them.

Shortly after I started handloading in 1980 I started looking for a good load in the 41 Magnum. Ken Waters' Pet Loads book stated his best load for the middle magnum was 21 grains of IMR 4227 behind a 210-220 grain cast bullet, if memory serves. I used that load behind the Lyman 410459 for a lot of years; it was always more accurate than I was, and Ken's statement that recoil seemed softer than with other powders was exactly my experience as well...
After using it in a 38 snub nose to a 357 6" Magnum with
110 to 158gr bullets both lead and Jacketed.....
I think it is much better suited for the 40 caliber or larger cases.
It did not do well in my 22-250 target loads.... SR 4759 shot much better.
Way too slow for the little 9mm, also.
I did have a few loads that were accurate but at twice the amount of powder.......... so why use it ?

218 Bee, 30 Carbine, 32-20, 25-20, and 22 hornet.
Works o.k. in 44 mag, and 357 mag as well.
Give it a try for reduced lead loads, or 110 grain half jacket loads in 30-30 or 303 Savage.

Since 2400 seems to only be produced one pound at a time, and you need to know the secret handshake to buy it I, have also been thinking about trying 4227 for my magnum calibers.
Is there any things that I, should steer clear of, certain brands of bullets, or types of primers, ect, ect.
Thanks.

Wow, two years later and I still have not finished that original pound of powder! It works very well with 110 gr. RN bullets meant for the .30 Carbine loaded in 7.62x39 but only my Yugo SKS will feed these bullets. I never tried it in the .22 Hornet or the magnum revolver cartridges. Just a week ago I went to see my component supplier and he had a lot of this powder sitting on the shelves. If I didn't already have so much other powder I would've grabbed more of this.

I tried it in my 357, do to having problems finding my go to powders. I found it very accurate and now I might just start using it over my 2400 110 and blue dot.

Same here, it's great for .44 mags.
