IMR 4831 is it safe for M1 Garand?

I recovered most of my reloading gear after three years of in being in my ex's storage unit, long story.

Anyways I have a batch of .30-06 loads that my log book says are Speer #2034 165grs with 57.0 grains of IMR 4831.
Ive completely forgotten where I got the load data from and when I look on the web I'm seeing that IMR 4831 matbe too slow burning to be safe in an M1 Garand.

Is this a safe load for my USGI M1?

Or should I pull them off the garand clips and leave them only for my columbian 30-06 mauser?

Not only no but Heck no!!!!! You can use any powder between IMR 3031 and IMR 4064. The loads you have are best left to the bolt guns.

Just what the man said. Absolutely not. The high gas port pressures can easily exceed the limitations of the gas system.

Stick with IMR3031 through IMR4064 and a few newer powders such as Varget.

Gonna crack or bend your Op rod for sure

That slow of a powder will have too much pressure when it reaches the gas port on a Garand. That will throw your rod back with extreme force, which in turn throws the bolt back with considerable force against the rear of the receiver. The chamber pressure isn't the problem.....the pressure at the end of the barrel when the bullet uncovers the gas port is the problem.

I would pull the tips and reload with a slightly faster powder.

4831 in the M1

I agree that 4831 is way to slow for a gas operated rifle. Even if the possible damage to the operating rod is discounted, You likely will have some extraction problems. The extractor may tear a chunk out of the rim.Many years ago when surplus 4831 was less than a dollar a pound, we tried 4831 in Rem. 742s, bad idea.
Try 4895, I think that powder was made for that M1.
The load mentioned, 57 grs. 165gr. bullet, pressure wise, is a mild load, works well in most bolt rifles, but is a little dirty.

Just to add to what all the other folks have said about this issue. About twenty years ago I bought a Springfield Inc. M1 Garand. Yes. They did make them back then, cast receiver and all. I had a lot of experience in loading for both pistols and rifles and went to work loading a moderate 3006 load using the IMR 4831 that I had in abundance. I had never heard of the gas port pressure issue, as I normally loaded for bolt guns.

Short story is that in very short order the op rod began to bind, it progressed to the point that the rod would jump out of the track on the starboard side of receiver. Teardown of the rifle revealed that I not only damaged(ruined) the oprod, but the hammer face had taken an extreme beating due to the violent speed of the oprod and bolt.

Looking back I feel blessed to have not received a face full of receiver heel. Trust me you do not want to go there.

sorry for bringing up a old post but? i am going to start loading for my garand so i started looking around, and only found this post.
i see you guys like IMR 3031 or 4064 for powder in a garand. i just picked up 250 FMJ 150grs bullets at the gun show this weekend. and was wondering what a good start for the powder charge for these?
i just couldn't bring myself to get any Korean corissive stuff!

4895 and Varget would both be very good choices. 4831 is way slow for a gas operated rifle in my opinion.

Corvetted,
I'd try IMR 4895 or IMR 4064 with 150 grain FMJ bullets. Try Winchester large rifle primers and either Lake City military brass or Commerical brass. If you go to Commerical brass and have to buy it, get Winchester brass. I get my brass from a guy who use to work for me when we were in the Army (free). He runs a county range and gets all the brass out of the cans. I just have to sort through it and throw out anything that looks like it has been reloaded. Then I clean it and sort it by brand, keeping only the Rem and Win brass. This brass is good enough for a rack grader. I use new Win or once fired (in my rifle) LC brass in my M1A and M1 308's.
Another place to try is email Sierra bullets and they will give you data that you know will not blow anything up.
One little tip, never use any loading data you receive from anyone other than the bullet makers unless you cross ref. it with published data from the powder/bullet companies. Some people's reloads scare the heck out of me!!! The only reason more guns are not blown up is the lawyers for the companies who make our guns demand that they be over built to be harder to blow 'em up.

Corvetted to continue building on this post and your question, I would try IMR 4895 and IMR 4064. In my '06 M-1's I have found they like IMR 4064 better. Loads should not go much over the middle of your re-loading charts.

Primers are up to you but I use CCI's and have for years. I would not use Federal primers in a M-1 or any service rifle due to free floating firing pins. Next time you chamber a round then pull it take a look at the primer. You will see a "dimple" in the primer and this is normal. Federals are the most sensitive of the primers and there has been well documented problems with the use of them in the M-1 and M-14.

Reloading for the M-1 can be very rewarding as once you find what the rifle likes they tend to shoot very well. Now go find a John C. Garand match and have at it as they are a hoot.

Nope some things happened before the internet Gasp ! I know you like to use the Federal match primers but with the free floating firing pin found in a GI gas gun and yes even the AR, there has been slam fires with a larger number being the Federals. Back 20 years or so ago the BATF found when using Federal primers in a AR they where able to get the thing to fire several rounds with one pull of the trigger. I'm not quite sure what they did the the rifle to get this but I do remember reading they where quite upset about it. Also important is the primer depth as high primers can lead to possible problems and may even be more of a contributing factor.

I have 308 M-1 in which I use the Federal match primers. My firing pin has been sprung and I use a SLED for single loading. I still get a larger "dimple" with the Federals than I do with CCI's. We all know the dimple is normal for a chambered round that has been subsequently removed.

Please keep in mind that I am a High Power competitor and the last thing I wish to do is ruin an expensive tuned service rifle in a process that will poke my eye out or worst. I have studied the situation with the goal of safe and reliable ammo that shoots better than Federal Gold Match or M-852 in my rifle.

I will agree the Federal match primers do make for smaller groups but just be careful. I do use Federal primers when loading for my wheel guns however.
