I keep some IMR 4227 on hand for my Ruger Blackhawk 41 mag. That gun loves the stuff behind a 250 gr WFN bullet. I get 1150 fps and outstanding accuracy. It also works very well with a 400 gr WFNGC in my 480 Ruger. It also runs about 1150 fps. I have had about the same results as everyone is saying in my 44 mags. The heavier the bullet, the better 4227 works. It also flows for me very well through powder measures. If I was limited to just one mag powder, it would be 4227. I like heavy for caliber WFN bullets and 1100-1200 fps will kill anything I want to tackle with a revolver. 4227 will easily provide that in most mag calipers.
IMR 4227?

I also like the WFNGC bullets.
My Redhawk's favorite is a 260 WFNGC over a slightly less than top load of 2400.
One big advantage is that you can get them sized for your chamber throats.
That is step one on the road to awesome accuracy.
I use the big WFN's up to 310 grains in 44's.
Just starting to play with them near Mach 2 in the 444.
Unfortunately, the recoil as I go past 3000 ft-lbs is becoming a challenge to these old bones.
I have a lead sled in the mail to use next week.
Yet another advantage of 4227: It's available!
I got an 8 lb jug should see me through most of the rest of my life.

Shot a bunch of IMR 4227 in 30 caliber M1 carbines little unburned powder which didn't affect function. Then some years later got one of the 357 magnum marlin 1894's and started out with IMR 4227. Got great accuracy and no unburned powder grains in the 20" bbl. Even tried it once in an old winchester low wall in 32-20. 100 grain lead bullets with no leading and good accuracy. Haven't tried it out in the 44 special yet. best thing I like about are the case filling charges as it's easy to see an overload all the powder won't fit. Good cast bullet powder for the old lever action cartridges like 30-30,32-40,38-55. Frank

The only load Hodgdon lists (using the now discontinued H4227) in the 44 special is 13-15 grains under a 200 grain JHP.
I suspect you are going to have unburned powder at these pressures (9-13 KCUP).
It's more of a magnum powder.
Let us know how it works.

I save my 4227 for necked down 357/45 GWM ... Use Accurate No.9 or Vihtavouri N110 for straight-cased magnums.
Anyone have a pet load for the 250xtp in 45 colt? Looking for something kind of warm to be used in an old 3-screw Ruger. I used to use 2400 but ran out a couple of years ago. I'm using Reddot for cast midrange loads. Does very well with either cast 230 RN or 250 SWC.
Do you mean using I4227?
Handloader #246 listed H4227 with a cast 270gr LSWC
22.0gr = 1116mv (from 5-1/2" Ruger NMB) ~21K cup
24.0gr = 1221mv ( <32K cup)
I've used 21 & 22gr in my 25-13 with MBC 255gr LSWC-HT. Both shot fine but left some unburnt powder, typical for loads less than full with this powder.

I've always had such good success with H110 in the .44 Mag, in all the revolvers I've owned, that I never got around trying 4227. But recently, back when we didn't know if powder was going to make a comeback, I was able to buy a couple pounds because it was there.
So I decided to try it for a .357 Magnum carbine, a 16" Rossi Model 92. This rifle, with Blue Dot and 158 gr. JHP's, consistently groups 2" at 50 yards, and apparently it likes this new powder as much as BD.
The best part was that my 2.5" 19-5 likes it, too. While I know that it's far from the best choice for a snubby, it's pretty accurate. I actually used that load to win one of the snubby contests right here at this forum, putting 10 shots into just over 2" at 10 yards offhand.

Finally loaded some IMR42227 behind a 250 grain SWC only 12 rounds at 20.3 grains CCI mag primer will shoot this later today or tomorrow. These won't go in the S&W but my Ruger SBH with a 10'' barrel with a scope.

Shot those rounds today and I'm going bump the charge by 1 grain. So far so good Sunday will be another test day. Not looking for warp drive but for accuracy.

I use 4227 in my 454 240gr loads. Most accurate and least abusive load I have found
I was in my reloading books......
I was in the books last night and asked the question, "Why is 4227 rarely discussed as a more energetic powder between reloaders but it's all over the data tables. I'm looking for something that will give more velocity than Unique or other medium burners but not full magnum.
I think IMR is best known as 'rifle' powder. After all, IMR stands for "Improved Military Rifle" and they don't have many handgun powders in their product line at all.

I have noticed at the Hodgdon load data site they have quite a lot of data for the H4227 but little for the IMR version.
Since the "H" version has been discontinued this is curious.
At least in a caliber where this is the case the "H" data would give one an idea where to start with the low load and IMR 4227.
