4227 uses?

[Idaho45guy]

Had lunch with my dad yesterday and he mentioned that he bought 8 lbs of IMR 4227 for a .32-40 Scheutzen match rifle.

He sold the rifle and still has the powder and offered it to me for free. The powder is probably 20 years old.

I shoot mostly 10mm, .40 S&W, .45 Colt, .308 and .30-06 AI.

Is it worth messing with it for any of my calibers?

It will work with boolits in .308 and .30-06 at target velocity. There is a classic "Ruger only" load with 4227. A little research will turn it up.

Back in the 60s and 70s IMR4227 was a go-to powder for 30 Carbine under a 110 gr jacketed, or cast boolit. Primary reason was it generated sufficient gas pressure and volume at the right time from ignition to operate the M1 Carbine operating slide.

In the early eighties, during the heyday of Sillywett shooting it was THE powder for the 44 mag and cast boolits.

I use a lot of 4227 in my Ruger handguns,, especially the 44's & 45's. It's also excellent in the 357 Max. It's a very very good powder.

As others have said, it’s a great powder that will work in many applications! You be lucky.....I waited/searched for almost a year for 1 pound to try out in my 460 S&W! memtb

Thanks for the responses! Looks like I'll have to give it a try.

Friend Outpost75, I’d be very interested in hearing your specifications for “full charge loads” for the 32 H&R and 32-20. My newly acquired Blackhawk Buckeye Combo 32 should love them! I used to keep a little 4227 for my 32-40s, but had too many other powders I liked better.

In the Ruger you can fill the case with 4227 with as much as it will hold using a drop tube and with 1/8" compression by the seated bullet, in the same manner as loading black powder. In any other revolvers don't exceed filling the case gently without compression.

For both .32 mag and .32-20?

Yes, assuming the .32-20 is a post-1918 heat treated S&W Hand Ejector or post-1930 Colt SA, or Official Police, but not a pre-WW2 Colt D-frame or Army Special.

While not giving the highest velocities in 450 Bushmaster, it does run a close 2nd, with accuracy being a bit better.

I use it in 10mm (revolver), .357 magnum, .300 BO, and .22 Hornet.

Great stuff.
