Imr 3031

[tawastom]

Ok here is the deal, My kid, called and wants to load some medium range rounds for his 30-06 M1917, This is ALL he has to work with, Lee sized to .312, 150 gr. cast w/gaschecks, wax lubed,IMR 3031, Not to be rude, but plz dont recommend 4895,Trail boss etc, this is ALL he has to work with. I have no experiance with 3031 in cast and was hoping someone can come up with decent data. Thanks

[webfoot10]

Hi tawastom: I use 48 grs. imr 3031 under 150 gr. fmj in my
M-1, pretty well duplicates military loads. For cast drop your
charge to 35 grs. work up from there, till you get a load that
works. The 1917 is a strong action, no problem with standard
06 loads. For cast size to .313 in the 1917. Hope this helps.

[tawastom]

not much difference than 4895 then, good, thanks !

[runfiverun]

I was just 5 minutes ago thinking nobody uses 3031 too much any more.
I had a little a while back and burned it up and remember thinking it was a fine powder but I never hear anyone talking about it.
then I open the browser and here is a thread on it. :lol:

Hi and welcome to the forum. From a Lyman Handbook of Cast Bullets....34-39 grains of 3031 w/150 grain cast bullets. I'ld start with the 34 grain load and work up. 3031 is a medium powder and it is very versatile; works well over a broad spectrum of rifle cartridges. LLS

[rintinglen]

4895 was a WWII development that was designed to be roughly equivalent to IMR 3031, but with shorter kernels to meter better. I'd start at about 32 grains and work up til I got to 42 grains, or until accuraccy falls off. For a 151 grain rn boolit, Lyman's third edition Cast Bullet Handbook gives 29 grains as the start and 42.5 grains max, with 1682 fps at the bottom and 2522 at the top from a 26 inch barrel. I've personally used 34.5 grain with good results from my sporterized Springfield.

I trust your "kid" has a load manual and more experience than here is my pile and I need to make this work. Blindly trusting information from you tube and random folks on the internet without checking load manuals might not be safe.

IMR 3031 was considered an excellent slow powder when it came out, and was widely praised in the gun magazines of the time. It is very forgiving of light loading, and so is excellent for use with cast bullets. It is also easily possible to put too much of it in a 30-06 case. Reliable, documented sources (e.g. loading manuals) are suggested.

Anybody can post on the Internet, even though we do have an exceptionally good group of people here on this site. There was a fellow in my shop once, who claimed to be an experienced reloader. As he watch me charge cases he commented "there's room for a lot more, why not fill them up?"

Gun shops are no better. A friend bought a Savage10ML-II and asked me to help him learn to use it. I told him to go to the shop and buy a pound of Accurate 5744. He came back with a bottle of Bullseye and said "the guy at the gun store said this was better, more shots per pound."

[TCLouis]

rintinglen said it best, BUT

I must first add

Clean the barrel

Clean the barrel thoroughly

Clean barrel again

Foul barrel with 5-10 plinker rounds with cast boolit.

Lyman Manual 3 rd edition data
150 grain boolit\IMR3031

29.0 1682

42.5 2522

Start at the bottom and work up till accuracy falls off.

Accuracy may fall off at two different points with that wide of a range of load data.

Being a cheapskate, I always use the lowest amount of powder that produces a precise load.

[mpmarty]

My favorite loading in a 30/284 (similar capcaity to '06) is 38gr of 3031 with a cast 175gr boolit. does about 2550 fps out of my 28" barrel.

[felix]

I like 3031 a whole bunch because it is extremely versatile with bore sizes and can handle light loads well. For example, 0.0005 case expansion is about perfect for it. ... felix

[Olevern]

best for accuracy in a little mini-Mauser I own in .223, one of my go-to powders in 45-70 and a good cast boolit powder in 30-30.

[randyrat]

+10,000,000 on IMR3031. Very accurate with the 30-30.You will find "the load" in your 06

[cajun shooter]

IMR 3031 is probably one of the best powders to have on hand at this shortage time. It is a top choice for .223,.308, 30-06 and 7MMmag for just a few. The go to powder for cast bullets in the 30 calibers. It is at times beat out by Varget but still a good one to have.
Always look in a "few manuals" before using any PC information!!
It is sad to say but there are people who have never even used a certain powder but will pass along things they have heard. I try to keep at least three pounds of IMR 3031 in my supply at all times.

From Lyman Cast Bullet Handbook 4th Edition:

They used Winchester WLR primers in Winchester cases to come up with this data.

Suggested Starting Load for IMR 3031 is 30.5 grains

Max Load for IMR 3031 is 41.5 grains

He really should buy this manual and not take my word for this...

I use it for 30-30 and 35 Remington most all of the time. It wouldn't surprise me if there's others loading for those calibers with 3031 as well. I worked up my loads for these two calibers years ago--don't feel compelled to change. Of course, nobody shoots 30-30 or 35 Rem any more--we never seem to hear anybody talking about them--at least not in the gun mags LOL.

[James2]

3031 has been one of my most used powders over many years. It is a good one as far as I am concerned.
I have used it in 222 Rem, 30-30, 30-06, 308 and 243.
I like to get data from bullet and powder manufacturers online. Other online stuff is interesting but suspect at times. Even if no ill intent is meant, typos happen too easily.

Do check loads in a manual or two for any powder or load.

[curator]

30 grains of IMR 3031 is my "go to load" for .30-06, .303 British, and 8X57 Mauser--all with 180 grain boolits. IMR3031 was originally developed for the .303 British cartridge to duplicate velocities of cordite loads, that's why it is "303"-1. It is a tad faster than IMR4895 but works in most applications that call for this powder.

[buck1]

Its a great powder. In fact if I could have only one rifle powder it would be IMR 3031.

[RugerFan]

IMR 3031 is my primary powder in a variety of .30 cals. In my 03A3 31 gns of 3031 pushes a 155 gn 311440 at 2017 FPS and is plenty accurate.

[nemesisenforcer]

The old standby for 3031 in the 30-30 is 30 grains, so I would think that is an excellent starting point.

[zomby woof]

I've found it very good with the 03A3. 180-210 grain boolit with 30-32 grains was the load for me. I did find the need for a Dacron filler. I had delayed ignition without it, that sucked.

[surfanarchist]

This powder is in stock at Precision. I just picked some up. Is it OK fro me to post this?

I asked a similar question a while back for a 200 grain boolit in the 30.06.. The answer I got was to start with 30 grains of 3031 with a grain or 2 of dacron on top. It worked well and is very accurate.

I always keep some on hand for 30-30 and 06.

[David2011]

Cool. I have a bunch of 3031 but don't like using it because it doesn't meter very well. A buddy wanted to know if it was OK to bring his ChargeMaster to my place and load some .308. Only thing was, he said he would really appreciate it if he could leave it in my reloading room for my use as well. Do I have enough brass to load 7 pounds of 3031 all at once? :)

[MtGun44]

Intended for .303 British (303-1), it should work fine in any similar cartridge, and it does.

Not as effient as slower (newer) powders, but still does very well in many rifle cartridges.

[pdawg_shooter]

3031 is my powder of choice for my 30WCFs. Have tried many other but none beat 3031.

[Sig]

3031 has proven the be the most accurate for me in my 308 with 150gn J words. Sorry I can't be of help with a load for your 30-06 as I don't have one.
