Home Forums Hunting & Shooting Ask The Gunwriters .270 .30-06 one powder?

All,

Is there a single powder I could use for both the .270 Winchester/150 (Partitions) and .30-06/180 (Accubonds) that wouldn’t be a compromise in one or both? I am not looking for “pedal to the floor” velocity, but I don’t want to leave a lot on the table. I’d like to get 2850 to 2900 out of both (22” and 24” in .270, 24” in .30-06.) Always looking for an accurate load, of course. Temperature resistant would be nice.

If there is not a single powder suggestion, where would you start with the .270 and .30-06? Again, temperature resistant would be nice.

Thanks so much,
Gun Doc

I don't know how Temperature resistant it is but IMR 4831 works great in both. In fact both my top load in each I use it. 56 grains in my .30-06 under a 200 grain Game King is one of my sweet loads while 56.7 Grains under a 130 grain Nosler BT or 130 SGK is my honey load in my .270 Win. I don't shoot 150s but IMR 4831 is listed for 150s in my Speer No. 9 loading manual.

Also, IMR or Hodgdon's 4350 does well in both also.

IMR 4350

2850 to 2900 fps in an 06 with a 180 grain bullet is kinda bordering on being a hot load territory...

your one best choice is going to start out with 4831 SC, or slower...

RL 23 or 26, H 1000....and it will be a full case...

The 270 load with a 150 grain, No problem with RL 19 or 4831SC to get 2850 to 2900 fps.

That's where I'd start, and then proceed directly to R-26. R-26 seems to work really well with 150s in the .270, not sure about 180s in the '06 though.

Way back when, I knew a fellow who loaded for the 22-250, 270, 280, and 30-06, and used one powder.....IMR4064. I do not know what bullet weights, or any other information. But, I do know that he and his son killed a truckload of deer using his reloads.

H 4350 or IMR 4451 would be where I'd start.

Rl 26 would be my next step. It is slow burning but is a Hi Density powder so more will go in the case.

H 4831 certainly will work in the 270 obviously. However it's NOT a hi density powder so you can't get enuff in the 06 case < IMO >


Good Luck


On a related note: I've chased 1 powder for multiple loads OR rounds BUT I figured out that it takes.....

X no. of pounds of powder to load say 300 rounds. I decided it does NOT matter if they're the same powder or not because you still have to have the same amount of powder........

AND sometimes you're better off using DIFFERENT powders for each --- less demand on a single powder. YMMV

IMR 4831 gets my vote, works well in both

I was gonna say that too. I don't think it will give top velocity, at least not in the 270, but it sure makes some accurate loads. And if you want reduced loads, it works pretty good too. I used it in 270 with 110gr bullets to make a reduced load for the kids (about 2,800fps) & it was <MOA.

H4831

GunDoc,.

Apparently some respondents missed the fact that you're loading 150's in the .270.

I've used a number of powders that work very well for both 150's in the .270 and 180's in the .30-06. Ramshot Hunter might be at the top of the list, though like some of the other powders mentioned so far it's a little temperature sensitive. Of course that can vary with specific applications, but in general it's about like the "traditional" IMR powders such as IMR4064, IMR4350 and IMR4831--not as temp-sensitive as many older spherical powders, but not as temp-resistant as the new IMR Endurons.

Of course, you might not desire or need much temp-resistance. I tend to value it, due to living where a wide range of temperatures is common, but between about 30 and 80 degrees Fahrenheit even the most temp-sensitive powders don't vary much.

Might mention that I've had excellent luck with H4831SC with 180's in the .30-06, both in terms of accuracy and velocity, and of course it works very well in the .270. In the .30-06 it requires some compression, but not "crunching." Haven't tried IMR4955 that much yet, but wouldn't be surprised if it works very well for both the applications you're interested in.

My experience with slightly faster-burning powders, such as the 4350's, you'll be giving up some velocity with 150's in the .270. The exception might be Accurate 4350, with in my tests has generally been slower-burning than IMR or H4350. Or at least my present batch is.

Like many new Wonder Powders over the decades, apparently many people think Reloder 26 will do the same fantastic things for all cartridges as it does for 150-grain bullets in the .270, or heavier bullets in the .243, but I haven't found it all that flexible. Where it works, it really works, but it isn't a universal solvent. In fact, a quick check of .30-06 data didn't find any listings for 26 with 180's, and a lack of data generally indicates a powder isn't particularly suitable for that applicatiojns. I'd be inclined to try RL-23 instead.

The latest versions of all Vihtavuori rifle powders are ery temp-resistant, and have decoppering agents as well. Just started fooling with the "improved" versions in 2018, but N560 is a great all-around powder in the general 4350-4831 burn rate.

It may not work.....but I’m planning on trying RL 17, in both! memtb

One powder is about as bad as the proposition of just one gun....

Someone is gonna have to give up his Loony card...

IMR 4064 or IMR 4350. I use the 4064 in my 375H&H, 30.06, .308 and .243.

I resemble that remark! memtb

Ram shot hunter.
I use big game in 06 with 168 TTSX and 165 SST for practice. you can use big game in 270 but no load date for heavier pills than 130gr.
Then hunter in 270 with 130TTSX or 140 SST for practice.... this load works very good. I have them set at the same CBTO. I think its 2.665

IMR4831 is my go-to with 180's in the -06. I get 2800 fps. Haven't tried 150's in the 270 but 4831 is my go-to for 130's.

D F, that would be a good Sig Line

4831 short cut works well and it also works good for volume loading if your in a hurry.
