Posted By: R_H_Clark Favorite powder for 270 Win. - 03/25/17
I'm new to reloading so sorry for what is likely a dumb question.I just want to know what to buy when I give it a first go.

My 270 shoots factory Nosler ammo with 140 BT's very well. I bought the Nosler ammo for the brass which I assumed would be very good. I want to try 140 BT and possibly an Accubond.

Which Accubond should I try 130's or 150's? 140's seem hard to get. Which powder and primer would you suggest for the most accurate loads? I'm not as interested in speed as accuracy.

Gun is a Forbes with 24" barrel and shot more 1/2 MOA and under groups than not with the factory 140 Bt's.
Re 26, Fed 210 primers, pick your AB bullet. I'd lean 150 for an all arounder.
Haven't tried RE26. Tried RE22 when I was working up loads but didn't have much luck. H4831 is the old standby. Hard to argue with 50+ years of success. It's scary accurate in my M70FWT.
Yep, H4831sc would be my first choice also.
Another vote for 4831SC under a 130 gr. Nosler. In my case, I prefer Partitions.
My M70 fwt likes IMR4350 with 150 Hornady SP.
4831sc was crazy slow in my 22" barrel. RL22 and IMR4350 was good with 130 grain ABs. RL26 is looking like it's gonna be awesome with 140 grain ABs.

Shootersproshop.com has 140 grain ABs and 150 grain Partitions in .277 right now.
RL22 has been tops in velocity and accuracy for me in several 270s with the 130 Sierra PH and Hornady IL. Ramshot Hunter is right there with it too and has worked very well with the 130 Hornady's. I've generally had better luck with those than H4831 myself. I want to try RL26 with the 150s...word is it's the schit.

Hard to go wrong w/ H4831. I also got great accuracy w/ RL17 under some 130s. I have some RL26 begging for some heat. We'll see.
I tried a new lot of H4831 a couple years ago that was 300fps slow from previous lots and accuracy was the worst I ever saw with my .270. I thought maybe I did something wrong until a friend mentioned the same thing and others have mentioned problems with it. It would be nice if that was an anomaly.
I've never had a problem with H4831.

It's my goto power in the .270Win for 130gr+ bullets.
H4831SC has worked like a charm in 3 270s with 130-150 gr bullets. In the accuracy department its a hard powder to beat IME

H4831 for 130's and RL26 for 150's...
I have used IMR-4064 and have had no problems.
IMR 4064 and 130 grn nosler partitions work great for me.
Try several different powders, as each rifle is different, and will prefer one powder over another one. I've only reloaded for one 270, over a 35 year period, and it loves H4831. I have never seen the need to go to anything else.
H4831sc and 130 gr here also
For 30 years it's been RL-22 and 7828, the new RL-26 loads sound very good though.

You'll be burning that load in your new BobinNH Commemorative rifle, eh? smile
Although there are probably several powders that will work well in a .270, a fellow can't go wrong by picking up a jug of H4831, some good 130 gr bullets and get after it

I will be adding a nosler partition to that mix, and yes I will be using it in MY BobinNH rifle. grin

It would be sweet!

James,

The .270 Win may be the exception to the above rule. If a .270 Win won't shoot with H4831 and 130gr C&C bullet, it won't shoot.

My families been shooting them for 4 generations and have yet to find one that won't shoot with that combination.
Yep, I've only loaded for two .270's out of at least a dozen that didn't shoot 130's best with H4831. The exceptions were an FN Mauser that preferred Reloder 19, and a NULA that shot extremely well with IMR4350. But those are exceptions that prove the rule.

With 140-150 grain bullets have found several .270 that also liked other powders, and got somewhat more velocity than with H4831, especially Ramshot Hunter and Reloder 26. But H4831 still worked well in them.

Exceptions not stated in hypotheses disprove rules. They're counterexamples by definition.

You're killing me John! grin
I don't own a 270 Win but thought (per my JOC readings) that IMR4831 was king. Curious why/how H4831 is considered top dog.... temperature consistency, etc?
Hod or IMR 4350
No, sir. JOC's powder was the original 4831, which was sold by Hodgdon. The IMR version came later, and is faster burning.

All of the above. I also have great luck with my .270's, 130's, and H4831 and I've been loading them since we still got the reclaimed WWII H4831 Powders, if that tells you anything about stability.
I also like the fact it is always consistent lot to lot, gives me a full case for my loads without compression and I can use it for more than half the rifles I own, so fewer powders to store in my reloading closet.

Have to admit I'm pretty old school and I tend not to venture far once I find something that works really well. Some of the other powders available now might be worth trying if I was just starting out.

Don't know why I thought it was IMR. I stand corrected--thanks.

Exactly. I read that to my executive assistant and she said, "Exceptions disprove a 'rule'!"
Unless the "rule" is that H4831 works well MOST of the time... grin

Yep I still have the steel cannister that 50 pounds H4831 powder came in for 42 cent sa pound.Used it all up years ago
My new favorite 270 Win powder is Reloder 26. Just yesterday I tried it out for the first time and got 3100 fps using 61.2 grains with a 140 grain Berger VLD out of my Browning A bolt. I also shot my normal load with the same bullet using 58.0 grains of H4831. That load gives me 2850 fps. Both loads grouped 3 shots into less than 1/2 inch at 100 yards. The faster load was about 6 inches higher on the target. smile

I use IMR 4350. Good groups.
Is there published data for RL 26 and 140 grain accubonds out there? I could not find it anywhere.

Thanks

Those aren't NAB data but between the data for 140 gr Berger and the data for 150 gr bullets you can make a determination on what load to start with. 2 cents.
