How do you use IMR 4831? I've tried it in a few rifles with mediocre success but still have a couple pounds on the shelf and could grab 8# for a reasonable price.

Currently loading for 243, 270 Win, 7mm-08, 7x57, 308 and 30-06. I see it mentioned in various recipe books for each of those cartridges, but curious about which applications others are using it. If you have some good accurate loads to suggest for any of the cartridges mentioned, or others for that matter, feel free to chime in.

Thanks,
Rob

I use it in my 25-06

I use it in multiple calibers. 30-06, 25-06, 7mm rem mag, 280 rem. and couple short mags. Up close to max usually. Has a little faster burn rate than H4831.

257 Roberts and 120's

Should be very good for your .270 and .243.. The 06 with heavier loads... It is a top performer in my .25-06, but you did not mention it..

Me too, with 100 grain bullets Also used some in .30/06 with 150 and 168 gain loads, 270 130 grain too

.375 Ruger. Cannot get enough in the case to get in trouble with 235-300 gr weights. Very accurate. With 300s can match max velocities given by 4350 and RL17.

.30-06 w/180s and up. .300 Win w/150 and 168 gr TTSX, also 180 gr cup/core bullets. All very accurate.

30-06 and 190gr Hornady BTSP interlock, which is now discontinued.. It was a great combo in my rifles..

.338 WinMag plus others mentioned

I use it in a 270 to launch 140 Accubonds. Its a very versatile and useful powder to my way of thinking.

IMR 4831 is my go-to in the '06 with 150 gr bullets. Yes, not a typo. Mostly Win brass, WLR primer, I fill the case to the base of the bullet, comes out around 60 to 61 gr...in my case Hornady GMX copper 150 gr. Chrono at 15 ft avg 2890 fps. 22" bbl M-70 FWT and same in Remington Model 30 Express. 1 1/8" 5 shot group at 100 pretty common and repeatable. No unburned powder in bbl and good brass life. Also you can sub RL19 and VV N160 for about the same results. Actually the VV N160 has a slight edge in accuracy and velocity.

I tried it once in the mid-'70s when my gunshop was out of H48431. I used it for loading .25-06. As I recall, results were comparable to H4831 but with slightly less powder. I prefer H4831 only because I've used it a long time in many cartridges and it's allegedly more temperature resistant than the IMR version.

Have used it in 243,270 and 30-06 with good results.

I’ve used it with success in the 270. Where it really shined for me was the 375 H&H with 300s, super accuracy.

simple way I suggest to people who ask me...

if you would use H 4350 in a load, then IMR 4831 is pretty close, just a little slower...

I don't think you can exceed SAAMI specs in an 06 sized case with it... I know you can't exceed SAAMI specs in an 06 with H4831...

but then for an 06, I am more along the lines of a 4064, 3031, RL 15, IMR 4895 kind of guy.... same with a 270...7x 57, 260, 243 .

Should work fine for heavies in your '06, and about any bullet weight in your .270.

I went through my reloading logs I keep last night and I have recently loaded IMR 4831 to test out in 338 WM and .30-06. I hope to try it out in my 260 Rem as well.

Nothing better with 139 and 140grain bullets in the 7mm Remington mag 3175 fps and tight groups. Mb

Saw and 8lb go for $325 last saturday morning.

As far as I'm concerned IMR-4831 is the t*ts for loading 6.5x55's. It shone in previous rifles and does so again with my current 6.5x55- a Ruger 1A. I was feeling antsy about the future last summer when I realized I was down to my last pound of it, so I bought a few pounds at what I thought was usurious prices: $40/pound. Nowadays I'm darned glad I did. (Although powders in general are starting to show up again in LGS's here.)

It is a good powder in 7mm Mag

I loaded it for years in my 06 with 180 gr. bullets, 300 WM and 300B. I tried it last year in my 280 AI but got slightly better accuracy with H-1000. In the present my go to powders are H-`1000 and H- 4350 and RL-15

I forgot one, the 264 Win Mag and Hornady 129 IL. Got a tack driver here with H4831

I use it for a 7RM with 140 AB’s and in a 300wsm with 168 Berger’s and get phenomenal accuracy with both.

I have burned a fair amount of IMR 4831 over the years. It was the first powder I purchased back in ‘92 for my .300 Win Mag...worked well in that gun as well as two others in the same caliber with 180 grain bullets. It is currently my go to powder in two of my .270 Winchesters with 140 grain Accubonds. Crazy accurate in my .243 Winchester with 100 grain Hornady BTSP’s

My only issue with it is I wish my inventory was a little larger.

I use it in a 22-250AI with 75-80gr bullets

This was my original plan and reason for buying a couple pounds. Maybe I just didn't try the right bullet/charge combo. I'm running 40.0 grain H4350 charge in my 243 pushing a 100gr Sierra GameKing and the rifle is stupid accurate regularly producing 3 shot 1/2" groups and able to hold 10 shots in an inch assuming I do my part 10x in a row (which is questionable). Anyway, I still have a couple pounds of IMR4831 - I may give it another go in the 243.

Beyond that, should I ever get drawn for a moose tag in NH or ME I'd load some 200s in my 30-06 and go to the IMR for that or maybe some 175s in the 7x57.

Anyway, thanks for the suggestions all.

I too have hit or miss results with 4831. I had one 270 that loved it and one that would not shoot it for crap. Both with 130 gr bullets. The same was true for 4350, the one that loved 4831 hated 4350 and vis versa.

Great powder for multiple cartridges and my go-to accuracy powder for my 280 Ackley 140's.

Get's the speed too.

Just picked up another 8 lbs for $200.00 at my local gun store, the last keg on the shelf.

Great powder for .270 and .280 with 130s-150s

243 Win, 25-06 and 270 Win.

I get nervous when I get down to less than 8 lbs of imr4831. It is THE powder for my 25-06 and 7mm rem mags. I use it in my 8mm rem mag, 264 wm, 25-284, 270, and 300 wm. It has proven itself over the years in my eyes.

"The powder" for me has been IMR4064. I use it in the 308, 30-06, 270 and have in the past 7x57 and 243.

Over the years I've burned a fair amount of IMR 4831 in a 270win and more recently a 280AckImp.

I don't think there's a 270win made that won't shoot lights out with 57grs of IMR4831 and a 130gr pill.

In my 280AckImp I've had decent accuracy with 140gr and 150gr bullets

Around 25 years ago Gander Mountain had a sale on it. I'd just bought a 25-06, dies and all the other components for it. I've been using it for that cartridge, among others, ever since.

.270 and 7mm.

Using it in my Winchester .270, I virtually duplicate Hornady Whitetail ammo, with the 130 Interlocks. Shoots great and kills deer well. 2970 fps.

My LGS has multiple 1# & 8# jugs of the stuff. Maybe I'll snag a 8# since the 270 is generally my go to.

Very good powder in 270, 280, 243, like said above.
My goto powder in my 280

It is great, but H4831 is every bit as good. I just tested a load yesterday (because I have no more IMR) and it was fantastic. The load was actually 100 fps faster, than the one that I like with the IMR. Same Interlock. Eight pounds should do you forever.

Doubt that. But it will last a while.

I bought a Weatherby Vanguard in .308 Win 3 or 4 years ago. My favorite load for it burns 45 grains of Varget. I went to load for it last week and I had to open a second 8# keg of Varget. That's only 1,244 loads out of the first keg.😁

Have some very good established loads with the h version in 270 also have good 30-06 loads with the imr 4350 is it necessary to step down between the h and the imr?

I use it in my 270 Win for launching 140 Partitions. I love it, and can’t find any of it in my area (like most things right now).
