hello fellas, im looking at starting reloads for the m1 garand, just wondering if anyone had any idea of projectile type(150 grn), powder type, and amount of powder would be good for loads for this rifle? i know it should not be too crazy so i bend my op rod... if anyone has any info on this that would be awsome!!!! thanks

as you probably know from looking into this, there are only a few types of powder that you can safely use in the garand, as far as i am aware there are only 2, i use IMR 4895 in my garand. i cant offer ideas as to bullet weights or loads but i would suggest getting a few reloading manuals, they are a huge wealth of information that is indispensable on the topic, and some even have footnotes about the garand

Hi Beretta123,
When it comes to powders for the Garand, the key thing is burn rate. The fastest Burn rate you want is from IMR 3031 and the slowest Burn Rate is from IMR 4064. (here is one chart to look at http://www.reloadbench.com/burn.html) Everything between those two powders is just fine to use. Your goal with these reloads should not be maximum velocity but instead pressure/burn rate along with reasonable-best possible accuracy and reliability. With a 150 grain bullet, don't exceed 2800 fps, preferably aim for 2700-2750 fps. When dealing with match quality, 168 HPBT or 175 HPBT running around 2600-2660 is your best bet.
Sorry, I couldn't find all the links I have collected the data from, so, you will have some reading to do. Just remember to check that the data is with in what your reloading book says, otherwise everything is fine.
Match-Grade .30-06
The .30-06 became America's first-line small-arms chambering in 1906 and served gallantly for more than a half-century until it was superseded by adoption of the .308 in 1957.
Shortly after the end of World War I, the .30-06 rose to dominance along with the 1903 Springfield in high-power competition. Although other chamberings nudged it aside in 1,000-yard events, the .30-06 remained competitive at shorter ranges and dominated service-rifle competition until the .308 gradually superseded it. Since then, a small but loyal following has continued to compete using the .30-06 chambered in Model 1903s and National Match M1 Garands. More recently, interest in the .30-06 as a match cartridge surged when the Civilian Marksmanship Program began selling surplus M1s, but only to buyers who could show membership in a CMP-affiliated club and a high-power-rifle competition classification.
Virtually overnight, CMP-affiliated clubs around the country began hosting high-power classification matches intended to qualify those who wanted to buy an M1. Having had a taste of competition, many of these buyers naturally wanted to use their new Garands in matches. As a result, competition with standard-issue M1s is one of today's most popular events.
This has generated a surge of interest in handloading .30-06 match ammo. But loading for a semiautomatic rifle is a more complex matter than cranking out hunting ammo for a bolt action. A few additional steps and precautions are necessary in handloading for an M1, and this makes all the difference in loading ammo that is accurate, reliable and safe. Having said that--don't worry, it isn't hard to do.
The M1exerts considerable force in stripping a cartridge out of the clip and transporting it into the chamber. In most cases the firing pin is spring-loaded and free to move to some extent by its own inertia. Combine this with poorly assembled ammo, and you risk a slam fire--an accidental discharge as the bolt closes. Several factors contribute to this possibility. For example, a floating firing pin as described above can move forward in its channel and strike the primer lightly. If the primer has a relatively thick cup, this causes no problems. If the cup is thin or soft, it's possible for the cartridge to discharge. A protruding primer can also cause a slam fire.
Here's how to minimize this risk First, use primers by such makers as CCI, Winchester and Remington. Some other brands use softer cups that may contribute to a slam fire. Second, use a uniforming tool to ensure that the primer pocket is cut to the correct depth. A uniforming tool is machined with a preset stop that prevents cutting the pocket too deep and will also remove any accumulated fouling that might prevent seating the primer to the bottom of the pocket.
Full-length resizing is essential. To ensure proper functioning in an M1, the cartridge must chamber without the slightest resistance. However, you must take care not to set the shoulder back, creating excessive headspace. It's not enough merely to neck-size cases, as is often done to obtain top accuracy with a benchrest rifle. This can result in balky feeding--even cause the rifle to fire out-of-battery. This could inflict serious injury to the shooter or bystanders or, if you're lucky, simply cause a stoppage that is very difficult to clear.
New or once-fired name-brand brass is a good choice for match loads, but remember to sort cases by headstamp. As you use the cases, separate them according to the number of times they've been fired. After two firings it's a good idea to use them for practice ammo only. I used the recently introduced Nosler Custom brass, which is made to exceptionally high standards. Military surplus cases--except for match brass fired in a service rifle--may be more trouble than they're worth. Non-match military cases have a primer crimp that must be removed by reaming or swaging before they can be reloaded. Also, if the cases were fired in a machine gun, they may be stretched or bulged, making them unsafe to reload.

Match Grade .30-06 Loading data. WARNING The loads shown here are safe only in the guns for which they were developed. Neither the author nor InterMedia Outdoors Inc. assumes any liability for accidents or injury resulting from the use or misuse of this data.
Chamber dimensions for most M1s are generous enough that a standard full-length-resizing die is suitable, but a small-base die such as the one made by RCBS is even better. A small-base die is designed to restore the case body to near-unfired dimensions. This provides additional chamber clearance for trouble-free operation.
Neck trimming to a maximum case length of 2.494 inches also contributes to reliability. However, neck turning is not advisable. Removing thickness in the neck may cause insufficient tension to properly hold the bullet and/or short case life because of split necks. Additional preparation such as flash-hole deburring is optional but will contribute to obtaining match accuracy.
The M1's gas system is designed for the pressure curve of GI ball ammunition. It's not adjustable to accommodate markedly different burning rates. IMR 4895 or H4895 are excellent choices for M1 handloads. However, several other powders also work well.
Slower-burning powders than those listed may introduce excessive pressure into the gas cylinder and create unnecessary stress that could batter or break the components of the M1's operating system. For the same reason, do not exceed maximum loads listed.
I've listed loads with bullet weights from 150 grains to 180 grains. Palma Match competitors usually prefer the 150- to 155-grain bullets while National Match Course shooters generally use 165- to 168-grain bullets. The Sierra 168-grain HPBT MatchKing is a long-standing favorite, but don't overlook other choices.
For 1,000-yard matches, many continue to use 168-grain bullets, but the heavier Hornady 175-grain A-Max and the Lost River Technology M40 168-grain VLD have begun to assert their ballistic superiority at long range. With no lead core, the Lost River bullets are very long for their weight, even longer than the 175-grain A-Max. This necessitates deep seating and possibly adjusting the powder charge downward. This company and a few others offer heavier bullet weights in a .30-caliber VLD design, but in my opinion, these are too long for use in the M1.
Match-grade primers are not the best choice for M1handloads. Standard primers such as the Winchester WLR, Remington 71?2 or CCI 200 have relatively hard cups and sufficient energy to reliably ignite .30-06 powder charges. It's worth repeating that primers must be correctly seated below the case head.
I used a Ruger M77 bolt-action wired to an Oehler M43 Personal Ballistics Laboratory to test velocity and pressure of my handloads. Powders tested included some old standbys and a few recently introduced types chosen for their burning rates in the "medium" range. All proved to be suitable, but one point needs to be emphasized Data for apparently similar powders are not interchangeable.
In my test, I looked at both IMR 4895 and Hodgdon H4895. I reached maximum allowable chamber pressure at 49 grains with IMR 4895 and at 46.5 grains with H4895 (with a different bullet). The H4895 yielded somewhat lower muzzle velocity at the maximum loading, but it edged the IMR 4895 in accuracy (although the IMR powder did very well). The important message here is this Switching data between these two powders might damage your Garand or cause injury.
For most events, a 168-grain bullet is the best choice. Although the Sierra 168-grain MatchKing has achieved almost legendary success, both the Barnes 168-grain TSXBT and the Hornady 168-grain A-Max are match-grade bullets and deserve a fair trial. Nosler does not claim match-grade quality for its Ballistic Tip bullets, but don't overlook the 165-grain BT. I've tested it extensively for uniform density and concentricity and have been impressed.
To be competitive with an M1, you must put a lot of bullets downrange. U.S. military surplus ammo supplies are dwindling, and available foreign military ammo is of questionable quality, so handloading match ammo for the .30-06 is becoming a necessity.
A great service rifle such as the M1 Garand should not be condemned to be a conversation piece. It needs frequent exercise and not a little love. Feed it well with good handloads, and it will repay you.
I would highly suggest you get a hold of Hodgdon and ask them. My older manual had a section specifically addressing this issue.

If you are looking for accuracy, drop all charges by 1 grain and work up .2 grains at a time.

Hi MCP284,
Great info on reloading for M1.
Maybe it could be put as a sticky. Some stuff is outdated but still true.
I do remember, many years ago, when I started reloading for the M1 and found ( and read more than once....) much of the info listed.
Each and every time I sold an M1, I did ask about how the pig would be fed and how and who would look into it.
Used also to post the the FM 23-5 to get some solid foundation on learning about and using the M1 with lots of dos and don'ts.
regards,
BB
Thank you for sharing again.
