I am now down to looking for powders I can use in my magnums.
I found in a listing for IMR 4227 for 44 Mag. Rifle. the recipe calls for start at 26g of 4227 over a 200 grain lead lazer cast rnfp. My plan is to start at 24grains and working up to 26 grain.
From the first test load it appears fill the case.
I will be shoot this load in a Henry 44 mag.

Thoughts on this load.

I am away from home where my reloading manuals and data reside so I cannot advise on load data..

I will caution you about hot loads in that rifle. Some hot loads that worked fine in my 629 would stick in the chamber of my son's Henry .44 mag. rifle. He had extreme difficulty extracting the fired cases from his rifle. Be sure that you work up to the load you would like to use.

I used to use it for handgun loads for Metallic Silhouette. It's been quite a few years, and I was using it behind a 240 gr jacketed, but it was somewhere around 24 grains. With a 200 grain bullet I would think 26 grains would be in the realm of possibility. It's a fairly long stick powder and you may need a long drop tube to get it all to fit.

I've used a lot of it, in my 45-70... I wouldn't have any worries about using it in a 44, with the usual provisos already mentioned, (start low & work up). I'm with H Richard in that you may need a drop tube to get it to fit in the case. Lil Gun/H110/Win 296 would probably be better choices, but these days you've got to use what you can find.

Thanks guys for the information. The powder metered well and filled the case. I am more concerned about the load being compressed. I have not be able to find my normal powders so like many others I am forced to find other means to keep shooting. I have found a pound of Green Dot I can use for my 45 colt and my 1911. A couple weeks ago I found some Rim Shot Competition for my 9mms and 38s and 40.

I like 4227 in the 44mag, but it's at it's best with heavy bullets & near full power loads.

The most accurate 41 mag loads I ever assembled were with IMR 4227. The load was 21 grains behind the Lyman 410459, and they would shoot to one ragged hole off a rest at 25 yards back when my eyes were still good.

I am waiting on a shipment of 4# of IMR 4227 as we speak.

I use it in the 401 Winchester Self Loader cartridge.
Not a pistol round,,but it's nothing more than a 41 Magnum/Magnum.
I load the cartridge with 41Magnum dies and use .410 cast bullets,,though .408 is the designated factory diameter.
I wouldn't use .410 jacketed bullets in it,,I'd make a sizer for them, but so far the LRN and LSWC .410 pistol bullets work fine.

Anyway,,4227 has been the go-to powder for this cartridge for many years amoung those that do reload for it.
Bulky, it nearly fills the case to the bullet base on minimum loads,,and is a compressed load (Lyman Manual) with a max load.

Can't remember the load and I won't guess,,doesn't really matter. It's less than the manual says as I make brass from 7.62x39mm rifle cases and they have less capacity that the old .401WSL brass.
Burns clean, accurate in the rifle (1 1/2-groups at 50m), functions the heavy blow-back action rifle w/ease.

I've never used it in anything else,,like most powder it's hard to come by now so I keep what I have just for the .401.
Just my very limited experience with it.

I use 4227 a lot in the 445 supermag.
It is bulkier than 296/110 and may end up being compressed some in the heavier loads.
I am moving away from ball powder and it's narrow operating range.
You may lose a few fps, but in the Henry that's not going to be an important issue anyway.
I view it as a slower version of 2400.

Never in the 44mag, but 4227 is almost all I feed my 357 Maximums. Full power is where it works best. Yes it tends to fill the case which is why I buy it in 8 lb jugs.

I was able to get to the range to shot the test loads. The load of 24 grains was a good start load and performed well. I will now try 25 grains. I looked for any problems with the cases and saw non.

I was lucky this week. A local gun store I use often called to say they had received some powder. The owner said she had gotten some IMR 7625 and I could get 2 pounds if I wanted it. Yes I got the 2 lbs. I have not used this powder, but I will start building loads.

It's pretty good in the .30 Carbine also. Not quite the ballistic twin to Hercules/Alliant 2400, but close to it, and useful in about any cartridge which is typically loaded with 2400.

I think 4227 is a better choice for heavy bullets in the .44 Magnum than W296/H110 and a few others.

IMR4227 is a very good powder in .44 mag. It is my preferred powder in .460 mag. Most accurate loads are at or just below compressed. With light for caliber bullets, odds are your loads will be at or near compressed at the start charge. It also performs very well in carbines. I doubt you can get enough in a case with a 200 gr bullet to hurt the gun.

I've started using it for full power .357 Magnum loads. I found a pound last year when powder was at it's most scarce around here, and decided to give it a try, even though I was stocked up on H-110. It gave such good accuracy in both my rifle (Rossi Model 92) and revolver (2.5" Model 19) that I bought some more of it to use exclusively for the .357.

I might try it in my .44's, but I get such good results with H-110 for full power loads that I have no plans for that any time soon.

From my experience, you cannot overload a 44 Mag with 4227 if you wanted to. Burns just a tad too slow to achieve the velocity of 2400, but very accurate.

My very first handloads were with IMR4227 in 44 Magnum. Used a Lee loader and the dipper was right for the powder. Worked great then and will still work great. Seems to be kinder to guns and has less heat buildup. Very low flash. Less leading. If that was all I could get for the 44 Magnum it wouldnt hurt my feelings too much.

IMR4227 was designed for the pistol sized rifle cartridges. Will be fine in the Henry. Just follow standard work up procedures.

just scored a few pounds of it today.
I intend to use it in 357 for the wife's Henry Rifle, kinder gentler loads in 45-70 and build a coated cast midrange load for 30-06.
theoretically this stuff might be THE last word for the 460 and 500 magnums.
seems many thumb their noses at it for its tendancy to leave some unburnt powder behind in 357, 41 and 44 magnum. it has made it easy to find in the crunch.
I almost never made the LGS rounds without seeing a can or two. today I saw about 20

It is my first, and only, choice for .44 mag.

When I first started, I liked that the 4227 nearly filled the case to make a double-charge easy to spot.

As it turned out, now that I have been reloading for a few years, I still like the 4227 for .44 mag and special.

It is a bit "crunchy" in a Dillon powder measure, but I can't tell any ill effects from powder cutting.

Please note: In .44 I am strictly a plinker. I do not compete or shoot for groups.

You can use it in the 9mm pistol..............
but being so slow , you will get a few loads that "Stove pipe".

I was surprised that the action actually worked 8 out of 10 times !!

You did want "Sub-Sonic Loads"... right ??

First handloads were with IMR 4227. Very accurate and low heat.



I've loaded 38 special with it, leaves lots of powder behind...though very accurate. For 38 special and 357 mag, I found it works best with near max loads. For some reason a full case of the stuff burns better than half case loads.

One time I tried in in my 38 snub but it did not do to well.........
better with a 158 lead in the .357 Magnum with the same load.
