If I were to load some 130SSTs for a 270 what would be the best powder to use? Ive got RE19, 22, PP4000MR, PP2000MR, RE17 & 760. But I do have availability to other popular powders.

I have ran more than just a couple through my .270's and now use H4831SC in both of mine.

Thats definitely on the list, I see RE17 gives a lot of velocity over the other powders.

With the 130s I get the best velocity and accuracy from RL-22. Put enough in the case to get 3,150 to 3,200 fps. The heavier charges seem to be the most accurate, at least in my rifle.

465H&H

H4831, and RL22 are THE go to powers in the .270 Win.

There is no one "best" powder for every rifle chambered in .270 Winchester as every rifle tends to be a bit different in how it reacts to various components.

However, the optimal range of burning speed for powders with the .270 and the 130 grain bullet includes powders like H4831, RL-22, and IMR 7828. I personally use my rapidly disappearing lot of original surplus 4831 in my .270 for excellent velocity and accuracy. If I were to switch, I would first try IMR-7828 SSC. RL-22 should give you very good velocities, but tends to vary in burning speed quite a bit from lot to lot. If you want to depend on it I would advise buying enough of a single lot to last you for several years.

Some people swear by IMR-4350. It will certainly work in most guns, but due to its slightly faster burn will either top out at a bit lower velocity or will require more pressure to match velocities generated by the slightly slower powders.

Stonecreek is all over it...

The only thing I would add is that I have tried to restrict myself to Winchester brass over the years, as it seemed to hold a bit more powder than Remington. (Never tried Hornady or Federal) There were times I couldn't get 60 grains of AA-3100, which is MY go-to load, into an RP case. Never a problem with Winchester...

Rem cases, Federal 215 primers, 58.5g H4831SC gets 150g Nosler Partitions going at 3040 fps in my 270. Please work up slowly ...

RE19 for <110gr bullets & H4831sc for >130gr.

Could never get SST's to produce decent groups (possibly due to their shape meaning a BIG jump to the lands in both rifles we tried them in).

either TSX or AB 140 with 58gr of 4831SC

I shoot the same load for the 140 grain hornadys at the range. Very little difference between the 3 different 140 grain bullets out of my Tikka T3.

Wow, that's hot!

I've taken the 150 partition up to 57 grains of 4831 but never went any further.

I've taken the 140's up to 59 grains but I seem to loose something after 58 grains.

47-49 grains of IMR-4064 has moved a lot of bullets for me in several rifles with the 130 weight.

130gr. Hornady, Noslers, probably whatever and around 52.7 grains H4350 out of a 27.5" Lija bbl = 3100 with single digit variation and 1/4 MOA grouping. Best velocity out of 4831 but could not get the guilt edge accuracy out of any of the 3 270's I've loaded for.

Does a few hundred fps matter? Whatever you need to feel confident in your weapon.

2850 to 3100 with 130's and 2750 to 2900 with 150's has killed, guessing somewhere in the 200+ range of deer and antelope and a few elk for my wife and I over the years.

The 270 is capable of far greater accuracy than most handloaders ever get out of it. I think the reason is that they are always insisting on 3000+fps with whatever bullet instead of tiny groups at say 2850fps. Trust me, neither the game nor the paper knows any different.

I should've mentioned that the cases were once fired and neck sized only for that load. I've used this load for 30 plus years, that chrono'd velocity is from a 22" barrel by the way. It shoots nickle sized groups too. No cratered/flattened primers or sticky extraction. Every rifle is different.

Every rifle is indeed different. I use the same amount (58.5 gr.) of 4831 with 130 grainers and that's all of the powder my rifle wants. Velocity runs an honest 3200 fps from a 24.5" barrel. I've seen other .270's that only generated a tad over 3000 fps with 60 grains of 4831. Sure, primers, cases, bullets, and powder lots vary; but rifles vary even more.

Never call a man a liar when he quotes you a velocity from a rifle you haven't shot (despite the fact that chances are he is.)

I've been using the same load in mine ever since the first time I took it to the range....I tested other loads, lots of them, but always have gone back to the very first one.

For accuracy and deer killing my rifle prefers 130 gr. Hornady spire points over 62.0 grains of H-4831, in W-W cases, and fired up by WLR primers. Those will still put the first 3 shots from a cold, clean, barrel in 1-1/4" at 200 yards. And they have killed several LARGE pickup beds full of Mule Deer.

All of these are perfect powders for the 270 Winchester!

1. H-4350/IMR-4350

2. RL-22

3. H-4831

Thanks for all the replies, fwiw, Ill be using Fed brass, 130SSTs &210M primers. Does fed brass hold less powder than Win brass? Ill go check now to see for myself, thanks again.

60.5 gr of H4831SC COL 3.300 has given me 1/4" groups. velocity 3050

Definately better accuracy than IMR 4350

I load 57.5 grains of H4831 with Federal Match 215 primers - Federal brass - 150 grain partitions. They shot 5/8" groups the first time I tested the load. Still shoots great - also shoots to the same point of impact as Federal Premium 150 grain partition loads.

Have you chrono'd your load? Just curious as to how it compares to mine (I shoot 1 grain hotter)

I believe the answer is "yes". A number of folks have posted here that they cannot get more than 60 or 61 grains of H-4831 into any .270 brass other than Winchester's. Even with Winchester brass it is a compressed load.

Was told by the Hodgdon tech fill your brass up to the neck and call it your max, the bottom of the neck, btw. That came to 58grs.

I am using Vitavouri N550 in my...

Just loaded up 20 with 59.5grs RE22, we'll see how it works soon enough. BTW, Win brass holds 1 grain more than Fed brass up to the bottom of the neck.

My own Ruger M-77 MKII in .270 like both: IMR-4350 & H4350 powders with 130 grainers.

chuck375 - never have chrono'd the load - a friend of mine in Kerrville has a chrono - just never have done that - All I know is that it just flat kills - never had problem with it - kills as good as my 300 win mag with 180 grain accubonds.

Agree totally, mine has accounted for lots of elk, 5 black bears and finished off a grizzly. A 270 shooting 150g Partitions at 3000 fps does flat out kill. My youngest son just got a 550 lb Hog with the same load. Here's a pic ...

Load the 270 into the truck, drive to the store and trade it on a 338

Got no use for an "in between" rifle, I've got a 375 Weatherby and a 500 Jeffery if I need something bigger than a 270 ...

The best powder ever for the .270 was the old 4831 Surplus powder, sometimes called 4350 DATA powder, that Jack O,Connor shot, Back then you could buy it at Army Surplus stores and it even came in 150 lb. Stainless steel lock top containers within heavy wood boxes..I bought one of those containers in about 1981. I still have 25 or 30 pounds of that stuff..I can get a easy 3200 FPS or more with 62 grs. of it and any 130 gr. bullet with very mild pressures indeed, and that is out of a 22 inch barrel..Ocassionally some of it still shows up at gunshows and strange places..

I also use this "wonderstuff" in my 300 H&H and can come within 50 to 100 FPS of a 300 Wby, and equal the Wby with 200 and 220 gr bullets..

Otherwise, for the .270 I would bet 4831SC or RL-22 would be the best powder today..I have played with RL-22 in my .270's and got fast speeds and great accuracy. When I run out of my wonder powder, the transition won't bother me in the least.

Since the 270 seems to do so well with so many powders, try whatever you have on hand that has been mentioned.

Take caution with hot loading an SST bullet though. That bullet is the only one I've ever seen first hand blow up on a game animal. Just a thought but you might consider slowing that SST down since it is so frangible.

I'd go with 4350 or 4064, go for accuracy, and table the thought of impressive velocity.

HarrHarr... no good choice!

Chuck, thats a big hog, damn!!
