IMR 4227 Favorite Loads

[kaiser]

18.0 to 19.0 grains of IMR4227 in a .45 Colt case behind a 250 or 255 grain cast bullet is a good load in a S.A. Colt clone, without stressing them out. I've also 4227 with cast bullets for a .444 and .45/70 rifle; which works great for plinker loads, and is satisfactory for close range deer hunting. I believe Hodgdon's market both IMR and H4227 showing powder load recipes as being identical.

BUY IT! Even if you find NO use for it (unlikely), you can trade it for other propellants. It works well in all the original magnum revolver cartridges, and is excellent for .45 Colt in the TC/Ruger loads. It usually gives higher velocities than 2400, but not quite as high as H110/W296. The UPside of the 4227s is that they are not prone to "misfire" if loads are started at 10% below maximum. H110/W296 specify no more than a 3% reduction in charge, which is less of a margin than I like to work with.

I'm wanting to use 4227 for my Ruger .357 Maximum behind a 195 gr cast bullet BUT I CAN'T FIND ANY FOR SALE ANYWHERE - all the big name sellers are OOS, even Hodgdon and a few places I've found want you to use PayPal, Venmo, Zelle, CASHApp, they say they have a lot of it but it seems likely a scam. Any suggestions?

Shyda’s in Lebanon has a nice big stack of 8 pounders on the shelf. Bit of a drive from State college, but if you are in the neighborhood for some reason…

Thanks for the update, it would cost way more in gas than having it shipped from someplace. Midsouth has some in stock but when I try to check out they say they can't ship, store pickup only. I might call themon Monday to see what they say.

[imashooter2]

Oh, absolutely. But if something brings you down thisaway, they are worth stopping by even if you already found the powder.

Got some from MidSouth. I had my PO box in my account address and of course they don't ship to a PO box. Edited it, put my physical address in and then placed my order. It went through fine so I have both IMR4227 and Ramshot Enforcer on the way.

33 grains in the 35 whelen duplicates 35 remington ballistics, and is plenty for under 150 yard deer.

[Grayone]

Used in 300 BO and also for 122-125 grain loads in 7.62x39.

What bullet weight?

What bullet weight?

I use 200 hornady FTX intended for the 35 Remington.

Du Pont #1204, introduced in 1925, was directly replaced by IMR-4227 in 1935. 25gr to 30gr of #1204 was used in the 44-40 cartridge giving a 200gr JSP between 1,400 and 1,830fps (Sharpe 1937). IMR-4227 was superior and 29gr gave the 200gr JSP 1,890fps. No pressures listed for those loads but notes recommended by Dupont and we can assume a bit on the high side.

All rifle powders folks, so is 2400. 4227 is IMR's "Magnum" powder.

30-06 and 30-30 for cast boolits since SR4759 is discontinued.

Well, after finally getting my 4227, I loaded my first batch of .357 Maximum cartridges for my Ruger Maximum

Bullet: Cast 194 gr Bradshaw-Martin (cast and powder coated by member Contender)
Brass: Winchester, R-P, Starline
Powder: IMR 4227 18.5 grs
Primer: CCI 400 Small Rifle

Also did a batch with a little lighter bullet

Bullet: 185 gr powder coated (red) from Missouri Bullet Co.
Brass: Winchester
Powder: IMR4227 18.0 grs
Primer: CCI 400 Small Rifle

The earliest I'll be able to check them out will be the beginning of Oct. (will be going to Contenders range in NC for a Ruger get together)

From a 10" Contender barrel, 7.5 grains of 4227 and Lyman #438 mold. Extremely accurate.

[Four-Sixty]

I get excellent results with 16.0 grains of IMR4227 under 180 grain boolits in 360DW cases when fired from my Handi Rifle.

Question for anyone that has bought a new can of IMR 4227 (recently)

Where was the powder made ??? ....Shown on the back side of the label

Thanks

Ps where I am, not seeing any primers / powder / or Loaded stuff coming in ...... especially just before bird / hunting season ...

Well, last weekend I was able to shoot my loads in my Ruger Maximum. They shot great and the recoil really wasn't bad. Then shot a few from a friend that were 180 gr MBC's in front of 13 grs of 4227. Nice mild load and seemd to be very accurate also (we were shooting hanging steel plates). I think I'm going to use the 18-18.5 gr loads if I use it for hunting otherwise I'll drop the load down for just target, steel, plinking (plinking with a .357 Maxi seems to be a oxymoron )

The newest can of IMR4227 (a week ago) I got was made in Canada.
