When I was still actively hunting and shooting a lot I loaded my 44 magnum loads according to Keith. I put up several boxes of Elmer's favorite load of 2400 and 240 grain hard cast bullets. Over the years I shot a few off and then moved on to my 45 Colt. The other day when I was repairing the ramp on my Ruger I tested the gun with some of my loads from the past and I can honestly say, 20 rounds of these loads rattled my teeth. I shot several loads of Magtech 240 grain jacketed bullets and they are definitely not as stiff. I shot ten of my loads one day and then ten the next day. I think I will go back to mild 44 special loads for my target practice. Chris

This is a interesting article

I came accross an interesting article on the net, concerning the 44. I agree with everything this gentleman says, and recccommend people to read it.
 
Care and Feeding of the .44 Remington Magnum
by SingleShotLover
 
Somewhere, perhaps hiding under a rock in Afghanistan, there may be a lonely soul who hasn't heard of the .44 Magnum, but he may well be the only one. This cartridge has rated near the top of the list of popular loading dies for over 40 years with no sign of losing ground to more "modern" offerings. Bigger, faster and more recoil-producing rounds have arrived on the scene but offer no real threat to the "King" of the magnums.
 
Background
A former cow-puncher, guide and gun-writer by the name of Elmer Keith (now deceased) can claim the rights to be considered the father of the .44 Magnum round and its family of firearms.
 
Elmer had been pestering the firearms and ammunition manufacturing community for years to produce a hotter loading (complete with revolvers strong enough to accept these loads under regular usage) of the .44 Special using his 250 grain SWC (semi-wad cutter) designed cast bullets at a nominal 1,400 fps. No one was interested primarily because of the older .44 Special revolvers made of milder steel then in existence. The only solution was to create both a new cartridge and the guns in which to use it.
 
The most entertaining version of Elmer Keith's crusade is that he supposedly pulled off what had to be the most creative con-job ever perpetrated on the firearm industry: Traveling to the Smith and Wesson plant in 1953, he convinced the powers that be that Remington was soon to release a new cartridge called the .44 Magnum. Since he even had the specifications for the "new" cartridge (.10" longer case than the .44 Special) , S&W was convinced and launched a campaign to be the first manufacturer to have a revolver ready for the debut of this new cartridge. Elmer then proceeded to make a dash to Remington and inform them that S&W was planning a new revolver for a new cartridge to be known as the .44 Magnum. If they wanted to be in on the ground-floor, they needed to move fast; and by the way............here are the specs for the new cartridge!
 
A very entertaining story, but a bit hard to believe. I have no doubt that Elmer Keith was gutsy enough to pull off the events described, but I seriously doubt that someone at either Remington or S&W wouldn't have made a few calls to sort out details. More likely, Elmer probably used his considerable force of character to persuade both sides to meet and agree to the joint venture. However it came to be, Keith was by all accounts the moving force and the first Model 29 was shipped in December of 1955. Full scale production and shipping began in 1956.
 
Though a closely held industry secret until the announcement in 1956, Ruger also began producing .44 Magnum Blackhawk revolvers the same year. How? A Ruger employee found a handful of empty brass in an industry dump. Bill Ruger, not being stupid, had the necessary "heads-up" that he needed to roll out his own single action version of the .44 Magnum!
 
Revolvers and Accuracy
 
The .44 Magnum is available in several action styles by many manufacturers. There are single actions, double actions, single shots and semi-autos as well as several rifle designs. Since the vast majority of my experience with this cartridge was gained with revolvers, that is what we will discuss.
 
The unfortunate fact is that cylinder/throat/forcing-cone/bore dimensions vary wildly from manufacturer to manufacturer and even within the same line. I have found revolvers with chamber throats as tight as .428" and as large as 434". Match this with what should be the proper bore diameter of .430" and you can see that accuracy can suffer. Ideally, chamber throats should be .001 - .002" larger than bore diameter. My own .44s all have bore diameters ranging from .4295 - .430". I have opened the chamber throats on each to a uniform .431" and altered all forcing-cones to an 11 degree taper. Using .431" cast bullets, the resulting fit is about as close to perfect as you can get, and accuracy with all is top-notch.
 
Actually, when you look at the sequence of events that take place when a revolver is fired, it is a wonder that anything works!
 
Consider: The trigger is pulled and the hammer falls, driving the firing pin forward to detonate the primer. The primer detonation ignites the powder charge instantly creating a building gas pressure. When the pressure has reached a certain level, the bullet begins its forward movement creating an equal movement of the case rear-ward. (Remember- For every action there is an equal and opposite reaction.) The rear-ward progress of the case is arrested by the recoil plate and the case continues to expand to create a gas seal within the chamber. By this time, the bullet has exited the case and is passing through the cylinder throat while being subjected to immense pressure from the rear causing it to expand to fill the throat (known as obturation). Upon exiting the cylinder, it has to make a jump of anywhere from .002 to .006" (barrel/cylinder gap) and enter the forcing-cone where it hopefully gets centered and swaged to bore diameter. Now the poor bullet is subjected to the wrenching trauma of encountering the rifling and forced to not only proceed forward at speed, but take on a rotation before finally exiting the bore into the unfriendly world and hurtling toward the target (which it hopefully hits).
 
Add all of the above to the fact that the average cartridge is a loose, rattle-fit in each chamber and is seldom actually centered at time of ignition, the accuracy of any revolver is a true miracle.
 
Stay with me.......we are going to see how we can eliminate some of these variables by thoughtful loading techniques and practices.
 
Bullet and Powder Selection
 
The traditional load that any aficionado of the .44 Magnum can name without reference to any loading manuals is Elmer Keith's famous 250 grain cast SWC propelled by 22 grains of Alliant 2400 for an average of around 1,400 fps. This load is still one of the best (with a reduction of 1 -2 grains of powder since today's 2400 is a bit hotter than it used to be) and works well in many revolvers. With all respect to Elmer however, other loads and bullet styles work as well or better.
 
The .44 Magnum is probably best known for its accuracy and power using cast bullets. Cast bullets are both accurate and inexpensive to buy or cast as well as offering shapes and styles that meet many needs. They also offer the advantage of creating lower pressure and higher velocity when compared to comparable jacketed loads...in essence, free horsepower! The basic styles fall into three main categories (1) SWC Keith design (2) round-nose (3) LBT (Lead Bullet Technology).
 
The Keith style SWC is often copied (poorly) by cast bullet and mold makers. The original design calls for a square-bottomed grease groove, three wide driving bands of full diameter and a flat base. These full-diameter bands (particularly the front one) ensure that the bullet can receive a firm grip upon entering the bore without stripping or skidding across the rifling. The flat base allows for uniform pressure dispersal across the entire base to ensure proper obturation to seal the gasses behind the projectile. A true "Keith" designed SWC seems to shoot well in most reasonably accurate guns.
 
Today's bulk casters seem to insist on narrow drive bands and bevel based bullets. Bevel based bullets are probably more responsible for leading in revolvers than any other source. Gases are allowed to work not only on the base but to squirt up the sides of the bullet causing gas cutting and its resultant leading. The narrow drive bands allow the bullets to skid across the rifling before a grip can be achieved and also contribute to leading. Avoid these bullets like the plague.
 
The round-nose designs should be relegated to target and small game shooting. Their design is poor for penetration and shock transfer but can be used for practice or hunting small game with minimal meat damage.
 
The bullet style that I have used the most lately is the LBT design. This style is the brain-child of the late Veral Smith and offers an entirely new concept. The LBT design is characterized by a wide flat nose (meplat). Depending on the particular style (LFN - Long Flat Nose or WFN - Wide Flat Nose) the meplats range from .300" (LFN) to .340" (WFN) and create increased shock and larger wound channels than the Keith design. Elmer was operating on the erroneous assumption that the shoulder of his SWC design was causing much of the damage upon impact. Recent tests prove that this is not the case; only the nose meplat causes the damage in tissue with the shoulder actually existing in a near vacuum as a result of hydraulic effect. Naturally, a larger nose will create more damage while allowing for a heavier bullet without increasing length excessively.
 
I usually use the 270 grain LFN with a plain base (though gas-checked can be used) in my .44s. Using an appropriate amount of 2400, I easily clock 1,300 fps from my 5 1/2" Ruger Super Blackhawk and can usually keep 6 shots at 50 yards around 2". The WFN design at 320 grains runs just at 1,200 from the same gun but opens groups to just under 3" at 50 yards. My Ruger has driven the 270 grain load completely through two medium sized (110-120 pound) deer with no bullet recovery. The first one was at 40 yards and went through the ribcage without hitting major bone. The second was at 70 yards and destroyed the left front shoulder, passed through the lungs angling through the body cavity and shattered the right hip joint before exiting. The wound channel on both was impressive and the penetration of the angling shot was far beyond expectation.
 
Cast bullets should be lubed with a relatively soft lube and be cast to a BHN ( Brinell Hardness Number) to suit the pressure levels at which they will be used. How do you determine what hardness to order? Actually, it is pretty easy to do. Determine the listed pressure of the load you intend to use and divide by 1,422. Example: at the top operating pressure allowed the .44 Magnum by SAAMI - 36,000 psi (NOT CUP) divided by 1,422 equals 25.3 BHN. Remember that bullets that are too soft will lead, but so will those that are too hard. Gas-checked bullets can be a bit softer. I usually have good luck with BHN in the area of 20 to 22 unless I am working with heavy-duty loads.
 
Jacketed bullets of several styles also work well and are available from Hornady, Speer, Sierra, Nosler as well as Winchester and Remington among others. I am no fan of light bullets driven at high velocity in handguns. Light bullets driven at excessive speed seldom penetrate straight and usually prove no match for substantial bone. Hollow points may or may not work at anticipated velocities, which is why I prefer the reliability of heavy hard cast bullets and let the design do the work.
 
Powders that work best in the .44 for hunting loads usually start with W-231 on the fast burn-rate side and run through Unique, HS-6, HS-7, Accurate 7, Enforcer, Accurate 9, 2400 and H-110/W-296 (most reloaders are aware that H-110 and Winchester 296 are actually the same powder). A new-comer to the scene, Lil Gun, is showing a lot of promise and may end up being the powder of choice for cast bullets. Its cooler burning flame seems to not scorch the bullet bases as badly as 2400 and may make a cleaner burning, lower pressure load.
 
Interestingly, 2400 doesn't respond well to the use of "magnum" primers. Regular large pistol primers usually provide better pressure uniformity and produce a flame that doesn't scorch or etch the bases of cast bullets as badly as magnum primers. H-110, on the other hand, seems to require magnum primers for best efficiency.
 
Brass is available through virtually everyone. IMI, Midway, Starline, Remington, Winchester and Hornady offer new brass as do others.
 
Loading Tips
 
One of the major factors affecting accuracy with straight sided cartridges is case length. Make sure that all cases are uniformly trimmed. After trimming, de-burr only the outside of the case mouth. The sharp edge left on the inside of the case mouth as a result of the trimming assists in a firm bullet crimp.
 
Use a firm, uniform crimp (I prefer a roll-crimp on revolvers and a taper-crimp on autos) that is enough without over-stressing the case mouth or buckling the case. Most of the powders used in the .44 require a firm crimp to develop uniform pressure, not just to keep the bullet in the case.
 
Adjust your sizer to size only to the web of the case if your revolvers will allow this. This allows the base of the case to remain a snug fit in the chamber to assist in alignment.
 
Choose bullet diameters that are a snug fit in the throat of your chambers. A .431" throat needs a .431" bullet. Add this fit to the base fit (above) and you have taken control of cartridge alignment rather than leaving it to the tender mercy of gravity.
 
Seat and crimp in two different stages. This is particularly valuable when using cast bullets. The gradual closing of the "belled" case mouth as the bullet is seated can (and will) shave material from the bullet. The best way to do this is to adjust your seating die to only seat the bullet and obtain a Lee Factory Crimp die for the actual crimping process. This die is easy to use and has the added advantage of making sure that all cartridge dimensions remain correct.
 
I actually use a Lee progressive press as a "semi-progressive". Since it is only a 3 station press, I size and de-cap all brass on a single stage press followed by priming using a hand-held priming tool. This also gives me the chance to examine every piece of brass for defects. I then dump all of the primed brass into the press hopper and begin loading. Stage 1 now becomes the expanding/powder step followed by bullet seating only at Stage 2. Stage 3 is a pass through a Lee Factory Crimp die for crimping and final overall sizing of the cartridge.
 
The Future
 
The future of the .44 Magnum is bright. Even with the onslaught of the new "super" magnums like the .454 Casull, the .475 and .500 Linebaugh, and the S&W 500 Magnum, the old .44 will always have its devotees. The excessive recoil of the challengers have created a large number of recoil related injuries. One highly experienced gun writer suffered wrist and hand injuries from only 40 rounds from the new S&W offering.
 
Conversely, the .44 Magnum can be mastered by anyone with practice and a proper firearm. It offers the power and penetration to handle any reasonable handgun hunting needs (with proper bullet selection) and is also capable of target quality accuracy. Reduced loads (or .44 Special ammo) make this a truly enjoyable cartridge to shoot by anyone.

.44 Loading, Sort Of

Chris, your report about rattling your teeth brought back a memory; specifically, getting to my saturation point with the .45-70. Loved the idea of the big old cartridge, I did. Read up on it, impressed with what writers like Dave Scovill said Alaskans and others were doing with the shell in strong modern rifles. Went variously through a Browning 1885, Marlin Guide Gun,  and the big beauty, the Browning 1886 carbine.  Loaded the 350 gr. to about 2200 fps, as I remember,  with no pressure signs,  but every time I touched it off I felt stunned for a half second, and I'm not very recoil-sensitive. Figured two or three brain cells bouncing around in all that empty space was the problem. Decided I didn't need that. Guess my short .300 mag will do for anything big that I'm actually going to hunt (mainly elk),  and the .308 for the medium game,  and call it good. I know there are plenty of guys that shoot bigger wallopers and do just fine, thank you, and I think Mr. Keith could shoot a shoulder-mounted cannon with aplomb.  But I want to like to shoot what I'm firing.
 
Which sorta brings me to gunsmith's post, and thanks for the article excerpt, gunsmith. Don't really have any desire to go beyond the .44 mag,  and have been happy with 23.o grains of W296 and the Hornady 240 gr. XTP, or 10 gr. Unique with the same bullet. I got the W296 load out of the 1987 book Handgun Reloading, Grennell and Clapp. They worked up accuracy, velocity, standard deviation, etc.,  for a number of different loads per caliber, and tested a number of the loads in four different handguns. The W296 load has worked out well for me no matter what .44 mag I'm shooting it through. But I'm working on loads for cast bullets and plan to shift to them when I'm satisfied. Thanks again for the good article.

44's and 45-70's

Amity: I too went through various phases with my preferences. Once I was proficient witht the 357 Python I just had to get a 44 Magnum! My Ruger SBH is the answer to that quest. When I was still in High School my grandmother gave me her dad's old Springfield 45-70 trapdoor rifle. I wrote about it in one of my tales "Me and the 45-70". I first shot it with Remington factory loads and didn't think it was too bad. Jump ahead to my new (for me) Marlin 1895 and there seems to be a difference. The recoil is tolerable but I seem to be more sensitive to it in my old age! I prefer my 45 Colt now and still shoot my 22 Scout more than anything. Chris

For what it's worth

For what it's worth, I load my 44's in the following configuration: 29.1 grains of 2400, 430. diameter Hornady XTP 240 grain bullet, and large pistol primer.  I target shoot with this load and hunt with it.  I have taken a black bear with it (as I wrote in an earlier post) and even small game.  I find this load accurate and deadly but not so harsh I can't shoot at targets for extended periods of time.

2400

Hi there Nova Scotia.
Wonder if 29.1 is a missprint?
I have loaded a lot of the old 2400 at 22 and 23 grains and think that was max in my books.

Hot Load?

Jason, do you mean 19.1 grains of 2400? 29.1 is kind of a way overload in a 44 Magnum with 240 grain bullets. Elmer's load was 22.0 grains and today's 2400 is supposed to be a bit hotter so most manuals say  to back off to about 21.0 grains of 2400 max. P.S. You beat me to it ACE. Chris

Question for gunsmith. On

Question for gunsmith.
On another forum I made the comment that the burn rate of 2400 is supposed to be different today that back in Elmer's day and was told I was full of it! 
I have been looking for something to back up my claim which was based on comments I had heard to that  effect over the years but I cannot find any info on that subject. In fact the changes to 2400 to make it cleaner burning may have actually slowed its burn rate?
Do you know anything that will help my argument?

Maybe

Hi Len: I think Alliant has reduced the recommended load because of burn rate etc.this site shows 21.0 grains as a max for a 240 grain bullet which is a grain lower than Elmer Keiths favorite load. I don't know if Elmer's load was hot or what but I hear everyone saying 2400 is a bit hotter than it used to be? Who knows but I would work up slow using bnew 2400. Chris

Hi Chris, I was hoping to

Hi Chris,
I was hoping to come up with some documentation to prove my point on the other forum but the more I look it appears that if anything the powder is a bit slower?
But no one should try and duplicate these old loads if a maximum load is desired it needs to be worked up for the individual gun. In Keith's day there were a lot of balloon head cases available which had more capacity and primers have changed quite a bit not to mention the variables in chambering, throats, etc. Keith was also known for pushing his loads to the max. I also suspect the load manuals ere to the safe side and you cannot blame them in this legal climate.

Horse's Mouth!

Hi Len: Nothing like going to the source when inquiring minds want to know. I got in touch with the Alliant people and their response was fast and courteous! Great when companies care about their customers and respond promptly. According to Alliant, 2400 is being made to the same specifications as always.... Of course they advise working up loads slowly because of variations in bullets, cases and primers etc. as is always prudent. Hope this puts to rest any misinformation as to the "hotness" of 2400.

2400 gives the same velocity

2400 gives the same velocity with Elmers loads it always did. It is the lawyers and recoil shy writers that have downloaded it. Elmers load only develops 26000 units of pressur. Far less than the max of 36000. It was chosen by Elmer because it did not lead the bores, gave good velocity, and complete burn in a 6 inch barrel. It is at the balance point for the powder, pressure wise, this gives it its great accuracy. Less powder, and the balance point is not reached, causing velocity irregulariteis.  Load 22 grains of 2400, learn how to hold that hog leg, and have a lot of fun.
