.44-40 & IMR 4227
« on: March 10, 2014, 02:48:00 PM »

I am looking for reloading information using IMR4227 in a Uberti Henry and a Pietta 1873 Colt copy with a 7 1/2 barrel.
I am using the Mav Dutchman 44 Cal 200 grain Big Lube bullet.

Safe pressures and accuracy are of my main interest, velocity is not a concern as they are not for CAS shooting.

The case capacity of the .44-40 at 40 gr water and the 45 Colt at 42 grains of water would suggest some compatibility of data.

What is the proof pressure of the .44-40 ?

Thank you.

Disclaimer: I have no experience with IMR 4227 powder and I am not an engineer.

However, 4227 is advertised as a "magnum" powder, and IMR does not list any use for that powder for 44-40.  Nor is that powder listed for 45 Colt loads, until you select "45 Colt (Ruger, Freedom Arms, and T/C Only)", and that is with bullets of 225gr and larger.  Neither the 1860 Henry nor the SAA are designs that are overly robust for hot loads.   I would suggest that 4227 may not be a good choice.

But what do I know?

Sail32,

The MAP (maximum average pressure) rating for the .44-40 is 15,000. Proof loads are generally 20-30% higher.

I have shot a fair amount of H4227 in my original '73 made in 1882. I don't know how that compares to your lot of IMR4227 so a disclaimer is in order.

My H4227 load for a 200 gr cast bullet is 17 grs. and for a 215 gr cast bullet, 16 grs.  Primers: Federal 155.  Pressures taken in a ballistic lab are right around the 15,000 mark.

There is some partially burned powder grains in the barrel and a little bit in the fired cases due to the lower pressure but that doesn't hurt anything. Accuracy has been very good.

The researching the web suggest that IMR4227 and H4227 are similar enough that there would be no noticeable difference.

Based on the case volumes and reloading information I would assume interchange ability between the .44-40 and .45 Colt.

I cannot see the manufactures Pietta and Uberti, making any difference between their weapons during manufacturing, steel, dimensions etc, except in the chambering.

My older copy of Lyman’s #47 does list a load for IMR-4227 between 16.5 and 18.5 grains for a 200 grain jacketed bullet, but I am shooting a lead cast bullet.

The possible difference of pressure between the bullets is a concern or perhaps I am just being too cautious. The difference of CUP and PSI pressure units was not helping either.

I found reference for 13,000 CUP for the .44-40 and 15,000 CUP for the .45 Colt

The 15,000 you mentioned is that CUP or PSI ?

Thank you for your information.

.45 Colt = http://www.cip-bobp.org/homologation/en/tdcc_public?page=4&cartridge_type_id=4

.38-40 = http://www.cip-bobp.org/homologation/en/tdcc_public?page=5&cartridge_type_id=2


From the pages;

.45 Colt =    M = 12.5   PT max = 1100      PK = 1265   PE = 1430
.44-40   =   M = 17.5   PT max = 1100       PK = 1265   PE = 1375     EE =  890 
.38-40  =   M = 17.5   PT max = 1150     PK = 1323   PE = 1440     EE =1945   

It looks like a typing error for the .45 Colt and it should be;  PE = 1375

CUP psi

.45 Colt =    PT Max = 15954 psi    PK =  18347 psi   PE =  19942 psi
.44-40   =     PT Max = 15954 psi    PK =  18347 psi   PE =  19942 psi
.38-40   =     PT Max = 16679 psi    PK =  19188 psi   PE =  20885 psi


PT max     = maximum average pressure (bar)
PK         = 1,15 Pmax = maximum statistical individual pressure (bar)
PE      = 1,25 Pmax = mean proof pressure (bar)
M      = location of the pressure take (mm)
EE       = proof kinetic energy (Joule)
Notice: For conformal or tangential transducers the location (M) is that defined by the manufacturer.

I know this is another old topic but I wanted to add some information that could be helpful.

Pressuretrace II data [PSI] using a 20" MGM barrel

SAAMI lists the 44-40 as a Rifle Cartridge

Thanks to all of you for the detailed research and sharing the information. I reload for plinking and hunting in 44WCF and 38WCF.  Bryan, I was especially intrigued by your placement of the M1889 Marlin in Group II. Interweb browsing had brought me to the understanding that the '89 is  constructed of an older (read as weaker) steel and therefore not approved for hot loads. Care to expand on your knowledge for me?  I ask because I have an '89 in 38WCF and enjoy pushing the limits with it.  A bit dainty compared to the robust M1873, but a fine rifle and easy to woods-carry.

Scubby, I love hot loads too but I also have a Marlin model 1889 that I have no desire to shoot hot loads in. I have a modern Marlin model 1894CB that I have shot a few thousand hot loads through.

Keep in mine that I can always be WRONG but I have done my best to search very deep, almost daily, to gather what truths I can about the 44-40/44WCF cartridges and the firearms chambered for them.

Get you a copy of Lyman's 49th handloading manual. Lyman lists 19 rifles chambered for the 44-40 separated into two groups. 10 rifles in Group I and 9 rifles in Group II.

Lyman lists hot loads as high as 21,900cup for Group II rifles. I have loaded and shot both Lyman's Group I and Group II loadings. I, thus far, have tested nearly 500 shots with the Pressuretrace II strain gauge Module, my 20" MGM barrel, and only TWO of my loads came in higher than Lyman's hotest load. I have not tested Lyman's high pressure Red Dot charge but nonetheless only two of my custom charges came in higher than Lyman's highest result.

Tons of information on the 44 Center Fire Cartridge website. Question everything...keep an eye out for errors!!!
https://www.44winchestercenterfirecartridges.com/

Also, if you want some awesome factory loads, go get some of Buffalo Bore's 44-40 "Heavy" loads, said to be loaded within SAAMI's 11,000psi/13,000cup limits. These are the loads I used as my "control" for the pressure strain gauge tests.

If it was going to be a common load for rifle and pistol, I would load for the pistol, for which I would not stray from data published by common, formalized sources. Lyman told me that 700-x gave their best result in 200 gr lead, and at .430 it was so accurate and nice shooting in my Uberti 1875 Remington Outlaw that I have never tried anything else.


I use a lot of IMR 4227 in 41 Magnum/210 gr, 44 Magnum/430 gr, and my 45 Colt Redhawk/250 gr. Considering what it does to the brass at near compressed loadings, where it performs best, it would never occur to me to use the powder in 44-40.

Both IMR4227, 2400 and a few others, for some reason much to the surprise of folks...is in the manual.

According to the Lyman manual, for the 200gr JHP Speer #4425, The low end IMR4227 gave them the best groups. For the Lyman 427666, SR4756 low end gave the best groups as well as for  the Lyman 427098...all Group I loads.

Lyman lists Unique, 2400, IMR4227, Bullseye, 700X AA#2, SR4756, Red Dot and Green Dot pending bullet used.

I have a special Reloder 7/210gr JHC Sierra load (1,403fps) that gave me 17 shots in a 4" group at 100 yards. Another Reloder 7 load (1,373fps) with a 240gr SWC that gave me 20 shots inside a 4" circle at 100 yards. Loads range between 11,000psi to 13,000psi depending on the bullets used.

I have discovered that 40gr of Swiss FFg compressed about .17" in original semi-balloon head cases produce 14,000psi while 40gr of Swiss FFg in modern RP cases with a .21" compression results in 8,843psi...basically 10 shot averages.

Oh wait I forgot, Lyman's 700X gave them the best Universal Receiver accuracy....I was referring to rifle loads. For revolver loads they also list Nitro 100, ZIp, N340 and True Blue

Since you corrected yourself at the end, perhaps you could edit out the beginning where you dismissed what I wrote.


Note that the first sentence in Lyman's rifle section on 44-40 reads "these loads should not be used in handguns...".


It was a good catch that IMR4227, even A2400, actually is listed under 200 grain handgun. I wouldn't have been drawn to use of a magnum powder. Your results using those powders is enlightening.


I think the answer to the OP's question is to buy a copy of the Lyman Cast Bullet Handbook. Use of IMR4227 is clear enough, but since he wants to serve both rifle and pistol, the handgun loads seem the more appropriate.

Absolutely! I get so caught up in the rifle data at times......Sometimes I reply from my email rather than from the forum, it also gets confusing which email is referring to which forum too!!

Since this is a CAS forum I would suggest Trailboss' published load to be used in both revolver and rifle. If accuracy is needed along with a little killing power...Lyman's max revolver loads with Unique and 2400 yield good results.

On a side note...here is a video of my high pressure IMR4227 260 yard target hit with a 240gr SWC from this morning's trip.


Of course, this load is not for revolvers or 73' type rifles.

If it is not in a reliable loading manual developed by people from a complete ballistics laboratory with pressure gun and so forth don't do it.
"Data" produced  by Earl Bagadonuts will get you or some one near you hurt and an expensive gun ruined.

I learned about hand loading from a book by Phil Sharpe The Complete Guide to Handloading with powders like Lightening and HiVel#2
to name a few.

And that, my friends, was a long time and many pounds of powder and bullets ago.

I do not claim to be an expert but I do claim a few years of experience.

According to the Master Gun Plumber as "ex" is a has been and a 'spurt" is a drip under pressure.
I agree

Yes, it's called a CAB problem. That is the "Coalition Against Bryan". It is a split second signal loss, for the lack of a better term at the moment. Typically a "connection" issue but it has yet to be resolved completely. I got it down to it happening in maybe two in ten shots. Doesn't affect the pressure spike any thought.

Here is one for the PTII website from a 223 I think it was. Notice the blue line at the end. The secondary spike is from a lightly loaded charge published in a manual or two!  You know....always trust manuals!! I guess I "de-Bunk-ed" that one!

Hi Austin,
OK you have all the goodies to test and it works for you in your gun. However if someone else uses your data and has a kboom their lawyers may come looking for you.
The chance of a Kboom with real black gun poder is slight I would imagine but using that data in a pawn shop special mighr be another story.
Neat equipment though and i am sure people would like to see more from your testing with different combinations of bullet, powder, and primer with the .44-40. I don't have a .44-40 but it is interesting reading.
