Try to find a Lee second edition Modern Reloading.
Look at thirty eight and three fifty seven cartridges. Not sure why my numbers just quit working.
Well suited for .32-20, .38-40, .44-40, .30 M1 Carbine, .357 and .44 Magnum. The old military surplus 4227 you have pictured in the paper canisters was probably salvaged WW2 .30 carbine pulldown and also used for the M35 .410 survival shot load.
Good for cast bullet rifle loads in most .30 cal. cartridges, and for approximating factory velocity in the .32-40, .38-55 and .45-70. 4227 burns a bit slower than Hercules #2400 of the same era.
The ENEMY is listening.
HE wants to know what YOU know.
Keep it to yourself.
That’s good news! I load .357, 44 mag and 45/70.
Checked Speer manual number 10 and it shows IMR 4227. I looked at .357 and 44 mag. 300 Win mag. Quit looking .
I think you will like it in 38/357 especially if you are loading the heavy keith bullets.
I have had excellent results with IMR4227 in 38 special, 357 magnum in revolvers and a bolt action rifle, and 308 winchester in a lever action and break action rifle.
At least you should have a starting point to work up safe loads, the older lee books have many loads with 4227 listed.

I use it in small case cartridges like 22 Hornet and 17 Hornet
Here is a picture of the powder I am using, labeled as IMR 4227.

Excellent for all Outpost75 mentions. Additionally I'll add the 7.62x39 with 110 - 125 gr jacketed bullets. Use 22.5 to 23 gr. With 123 gr AK/SKS bullet of .310/.311 diameter it equals milsurp velocity and pressure.

I love 4227 in 357 mag, 30 carbine, 45 Colt, 22 Hornet and others.
It is my go to powder for accuracy testing a new rifle. It consistently gives me the best groups.

IMR 4227 is used in reloading for 350 Legend as well.
The 1990 IMR publication has data for many cartridges. I like it in 30-30 and it is a standard in the 32-40 for target work.

I used it in .44 magnum. Got good accuracy. Not quite the velocity as with 2400 or 296 but good accuracy.
Paper targets aren't your friends. They won't lie for you and they don't care if your feelings get hurt.
THG … here’s some 4227 loading data for your reading pleasure …. https://www.google.com/search?q=imr%...=firefox-b-1-m

if you go back through the old Lyman manuals or RCBS cast bullet manual there is load data using 4227 peppered throughout them in both rifle and pistol loads.
most recently I've been getting my most accurate 1200fps 45 colt carbine loads using 20 grains under a 265 grain bullet from mp454640
What is the difference in the two 4227's H & IMR?
[The Montana Gianni] Front sight and squeeze
both the same as far as I know
When Hodgdon bought IMR, they decided to keep IMR 4227 on the market because it out sold H4227- or so I read in a magazine at the time. A late friend preferred it in his 10-1/2 " Ruger SBH not because of the velocity but because of the year round consistency and accuracy.( the IMR version)
I'd be over the moon with your powder score- congratulations!
