Reloading is an enjoyable and rewarding hobby that is easily conducted with safety. But, like many other human endeavors, carelessness or negligence can make reloading hazardous.

The essence of reloading safety is proper handling and storage of primers and powder. By observing the following rules, the chance of hazardous occurrence becomes extremely remote.

Store powder and primers beyond the reach from heat and open flames. Do not smoke when Keep no more powder that needed in Immediately return unused powder to its original Don't use any powder unless its identity

357 Magnum was introduced in 1935 by Smith & Wesson with the intention of improving on the 38 Special round for hunting and law enforcement. The 357 case is approximately 0.12" longer than the 38 Special, a very original design feature at the time to prevent the higher pressure loads of the 357 Magnum from being used in the 38 Special (though not conversely). The 357 Magnum can deliver as much as three times the energy of the 38 Special. This magnum round started the great handgun magnum sweepstakes that continue to this day, though it retained its status as the world’s most powerful handgun cartridge for 20 years until the advent of the 44 Magnum. It remains a superb law enforcement cartridge and is sufficient for hunting small game up to deer at moderate ranges. Lead bullets make good small game and target rounds. Velocities, however, should not exceed 1100 fps, as undesirable leading of the barrel can occur in just a few rounds. Also, no loads are listed for the 148 grain wadcutter bullets since they are primarily target bullets and should not be fired at velocities exceeding 900 fps. When reloading 148 grain wadcutters, use 38 Special data. Many powders produced excellent results with the Hornady jacketed bullets. These powders include Blue Dot, AA No. 9, H110, HS-7, and 296. Unique provided the best performance with the lead bullets. N-110 provides near maximum performance with less

flash and blast than other powders.

reputation has been eclipsed by

newer developments, the 357 is still a very effective and useful cartridge. Although it was never originally intended for use in rifles, the cartridge has nevertheless found a home in lever-action carbines. These little rifles are

had our best results with Hodgdon’s H110 and Winchester’s 296, but any of

the slower numbers,

such as Accurate’s No. 9 and Hercules 2400 are worth

experimentation. The bullet selection available in the 357 bore size gives this

combination a tremendous degree of versatility. Sierra's 110 and 125 grain bullets give outstanding results for pests and plinking. The JHC designs of

140 to 170 grains are well suited to deer and other thin-skinned big game.

When

using heavy charges of slow-burning powders, magnum

primers and a

firm crimp are strongly recommended for best ignition, velocity and accuracy.

For rifles with tubular magazines, the 170 grain round-nose FMJ must not be

used in order to avoid primer detonation in the magazine.

heavier .357" bullets deliver more energy. It is nearly as powerful as the obsolete 351 Winchester self-loader cartridge. With 125 grain hollow points, the 357 is effective on

Reloading Data Introduction: The data listed in this section have been tested by our technicians and found to be safe when loaded with our test components and fired (under our laboratory controlled conditions) in our testing equipment. Since Lyman Products Corporation has no control over the manufacture of the various

load is noted as such in the data tables proper, it means that the

given combination of components produced the most uniform ballistics of any load tested utilizing that particular bullet design.

Bi

bd

components listed, the actual loading, choice or condition of the firearms and

components used, no responsibility for use of this data is implied or assumed. Components: The reader should bear in mind that the components listed are not of Lyman manufacture. Therefore, it is impossible that production changes affecting ballistic performance can occur at any time without our knowledge. If there is ever a question as to the correctness of the component specified, write to its manufacturer. Starting Load: It is essential that the reader begin with the suggested weight of powder listed in this bracket and work up slowly (following load development precautions) to his best performing load. The novice should use only the "starting load" for a period of time until he builds confidence and experience. Never decrease this charge as an increase in pressure could be encountered. Maximum Load: All loads which are listed as maximum were tested and classified as maximum by our technicians in accordance with our laboratory standards. Under no circumstances should these loads be exceeded, nor should they be quickly accepted by the reader as a safe working maximum for his particular rifle or pistol. Many reloaders misinterpret the meaning of the "maximum load." They wrongly assume that if a high pressure load proved safe in a test laboratory then it is equally safe under any and all conditions. This is not true. The reader must start with the "starting load" and work up his load carefully. Working with his particular firearm and component combination, he may encounter signs of excess pressure before he reaches the maximum charge listed. The technician classifies a load as maximum after carefully considering many aspects of its ballistic performance. The maximum average pressure of the load is not the only criteria. Often a load having an acceptable maximum average pressure will be rejected (or reduced) due to its erratic performance. Accuracy must also be considered, particularly when dealing with cast lead alloy bullets. In all instances, the maximum listing represents what our technicians consider to be the maximum working combination for the bullet, powder and caliber listed. These loads do not exceed SAAMI standards. Accuracy Loads:

-357 MAGNUM

- LYMAN BULLETS

Unless noted in "Comments," the accuracy load was not fired at targets.

The load, however, does have a high potential—assuming all external factors are optimun—for producing outstanding accuracy since uniform internal ballistics are critical to accuracy on target. You cannot have one without the other. Test Parameters: Velocities shown were taken at fifteen feet and not corrected to the muzzle. Each test string began with a clean dry barrel and consisted of ten shots. Loads exhibiting erratic internal ballistics were not persued. We had no problem with leading in any of our testing. Bullets: Bullet numbers are listed in the introductory specifications for each cartridge and in the headline above the appropriate data block—along with an illustration of that particular bullet. Please note these bullets are artists’ rendering. Comparing your bullet against the drawing could reveal minor differences. Furthermore, minor changes are sometimes made to bullets. These drawings, which appear throughout the data sections, are for general reference only and are not intended to be a precise representation. Bullet alloy is noted as is the exact weight of each tested bullet. Not all cast bullets within a given caliber are intended to perform equally. We have used them in the most appropriate chamberings. Powders: We have limited our testing to those powders which are manufactured in the United States and which are readily available to the consumer. The following

brands

are

listed:

Dupont

(now

IMR),

Winchester,

Hercules,

Alcan, Hodgdon and Gearhart-Owen. ’ Compressed Loads: All compressed loads are indicated with a +. Depending upon the volume of the specific cartridge case used by the reader, he may, or may not, have difficulty starting bullets in such loads. If the bullet will not start, reduce the load sufficiently so that 1/10" of space remains in the case neck. Start the bullet into the case and use whatever additional pressure is required to fully

seat the bullet. Failure to comply could result in a bulged case. Filler Wads: Dacron filler wads in the form of 1/4-inch thick batting were used in conjunction with cast bullet loads, where indicated. This material can be purchased in most yard-goods stores. It should be cut into squares, which seal the case. When developing a load, if a wad is desired, its should be used from the beginning as the charge weight is increased. It should never be added as an afterthought, once a maximum load has been established, since its presence could result in a pressure increase of 2,000 CUP or more.

COMMENTS: Never use 357 Magnum Loads in 38 Special cases as very dangerous pressure will result. Handguns can vary in groove diameter and itis wise to slug your barrel before sizing cast bullets. In order to maintain a maximum overall Cartridge length of 1.590”, it is sometimes necessary to crimp cast bullets on the forward edge of the first driving band. When using half jacketed bullets velocities must be kept above 750 fps. to prevent bullet jackets from becoming lodged in the barrel (the lead cores may exit the muzzle and Strike the target). To crimp half jacket bullets, form the crimp at the junction of the jacket and exposed lead nose. For target (mid-range) loads we recommend bullet #358495 with the suggested starting grains load. Bullet #358156 is extremely popular for heavy loads. Bullet #358429 closely duplicates the factory 158 grain semi-wadcutter. This is the Elmer Keith design bullet and makes an excellent choice for hunting. For light loads Hercules Bullseye and Winchester 231 are best. Heavy loads work well with a wide range of powders but you might want to try 2400 for your first accuracy tests.

DATA)

COMMENTS: The Marlin rifles chambered for the 357 Magnum cartridge have become popular and hence this data entry. Hercules 2400 would be our suggestion for combining accuracy and punch. Be sure to crimp bullets in place and use only blunt or flat point bullets in the tubular magazine of the Marlin. This data may, of course, be used in the limited production Ruger No. 1 single shot with any shape bullet.

.357 MAGNUM

357 MAGNUM Back in 1935, the 357 Magnum was introduced as the most powerful handgun cartridge in the world — unseating the 45 Colt for the title by a respectable margin. Shooters soon found out all that power came at a price in terms of recoil and muzzle blast, not to mention barrel leading with those early 158 grain factory loads. While the 357 Magnum has long ago lost the title of the world’s most powerful handgun to a long list of upstarts, it is still a very practical cartridge for self defense or hunting. For varmints, two or four legged, the various 125 grain jacketed hollow points are a good choice up to 1,500 to 1,600 fps, depending on barrel length. For larger coyote sized game, 140 to 158 grain bullets are more appropriate.

357 MAGNUM Considering the popularity of the 357 Magnum as a revolver cartridge, it was only natural that a number of shooters would appreciate a carbine or rifle chambered for the same cartridge.

Even in a longer rifle or carbine barrel, however, it is not a big

game cartridge — mostly because the vast majority of revolver bullets are not suitable for deer sized game at higher impact velocity. Conversely, .358 inch rifle bullets are, as a rule, designed to withstand much higher impact velocity and, as such, won’t expand at the run-of-the-mill impact velocities produced by the 357 Magnum. All that aside, a 357 Magnum rifle or carbine is handy to have around for smaller game or critters up to the size of coyotes. As a rule, handloads in rifles should not exceed the pressure limitation for revolvers, or upwards of 45,000 CUP. Longer barrels

offer enough velocity increase that there is no real need to horse

this little cartridge up to higher pressure levels.

- ACCURATE POWDERS

Introduction There has been a re-evaluation of the criteria for selecting data for inclusion. This means there will be some disagreement with previous data. The data in this guide takes precedence over all prior publications. Previous editions of this loading guide should be discarded. For instance, we left out load combinations that were ‘position sensitive’. This is what occurs when the load density is low. Velocity with the powder at the bullet is different from the velocity with the powder at the primer. More of these were noted with the ball propellants than with the extruded propellants. In light of the growth of IPSC shooting, 38 Super Auto loads that make the ‘major’ classification (bullet weight x velocity = 175,000) are identified. While we have tested many combinations of components in 9mm Luger to attempt to meet ‘major’ requirements, we have not been able to find a load that makes the power floor for ‘major’ without exceeding SAAMI pressure recommendations. And while we were able to find loads for 38 Super Auto, they were not with lighter bullets. Turn to the data section for specific details. In the charge tables, the ‘START’ charge listed for each load is our suggested beginning point with the components listed. There is the possibility that changing the named components could cause the maximum charge to be excessive, thus a reduction of the charge would be necessary. Some batches of military brass may require reducing the maximum chamber pressure in line.

charge by 8-12% to keep

If you find signs of excessive pressure while using loads in this loading guide, STOP TESTING and verify all data and loading procedures. If they seem to be in order, check with our lab facility before proceeding. Charge weights were obtained using industry standard pressure barrels. When time permitted, off-the-shelf weapons were used to obtain velocity figures. The guns used are noted. In reloading, the prime concern should always be SAFETY. Always wear eye protection when reloading, even when working with the ‘non-volatile’ components. Always keep the reloading area clean. Never have more than one propellant within easy

reach at any given time. Avoid having similar looking bullets of different weights on the bench at the same time. Read the safety notes before loading.

We have not found magnum primers to offer any particular advantage with our handgun powders. But, there are some rifle

cartridges where they were used. Handgun

loads using the slower powders

(No.7, No.9, and

1680) require heavy crimp and high bullet pull to insure consistency - particularly with cast bullet loads or in extremely cold weather. Be sure your dies are capable of this, otherwise the consistency of the load will be affected. In the text, bullet weights for cast bullets - identified by (L) are actual weights, not the nominal weights.

-357 MAGNUM - ACCURATE POWDERS 357 MAGNUM

L L

Introduced in 1935 by S&W for their large frame revolver, the .357 Magnum is

based on the .38 Special case lengthened V/10th of an inch so it could not be chambered in a standard .38 Special revolver.

The .357 Magnum was the most pow“SAAMI Spacilication erful handgun cartridge for nearly 20 years, until the arrival of the .44 Magnum. The .357 Magnum has been chambered in almost countless revolvers.

1s 359 (9, 118mm)

While it has been used successfully on deer, black bear, and even larger game animals, the 357 Magnum cannot really be recommended for thes e animals unless ranges are 100 yards or less and it is used by a skilled hunter. Within these li mitations, it can be quite effective on deersized big game.

The SAAMI Maximum Average Pressure for the .357 Magnum is 45,000 C.U.P. or 35,000 P.S.I. (Note: Most of this data is new and has been reshot using Copper Units of Pressure.)

320 MPa (46400 psi)

The .357 Magnum was first introduced by Smith & Wesson in 1935. The

goal of the new design was to improve the .38 Special cartridge to meet the requirements placed by handgun hunting and law enforcement. The solution was to lengthen the .38 Special cartridge case by about 3 mm (0.12") and strengthen it to stand considerable higher chamber pressure. The result was a handgun cartridge capable of delivering as much as three times the muzzle energy of the .38 Special. The .357 Magnum has remained probably the most popular magnum revolver cartridge ever introduced, despite the increasing number of shooting people enjoying cartridges of larger calibers. It is noted for its flat trajectory and great knockdown power. The recoil generated by the .357 Magnum is on a level most shooters are able to handle, too.

A number of good-quality lever-action carbines has been chambered

for the .357 Magnum, too, and, where allowed by the local regulations,

the .357 Magnum is occasionally promoted as a deer cartridge. If used by

of an experienced hunter capable of placing the right bullet in the right place at close range, it will get the job done most of the time. Asa hunting cartridge the .357 Magnum may be considered better as a varminter or a short range cartridge for small game. If swaged (soft) lead bullets are used, the muzzle velocity of those should not exceed 340 m/s (1100 fps), as undesirable leading of the barrel may occur in just a few rounds.
