I'm getting ready to help my neighbor work up a load for his 270 and i've never worked with this caliber before. We will be loading the 130gr Sierra Pro Hunter. I would really appreciate it if you guys that load for a 270 using a 130gr bullet would give some imput as to what is your powder of choice or what has worked best for you with this combination? Thank You! Mike

MY CHOICE HAS BEEN IMR4064 for the 130gr and the 140gr bullets.
I have tried a bunch of diffrent powders and most work fairly well
I had good results with H414 and AA2700
not so good with H4831 or imr4831.
I load for two rifles a 7400 remington that I keep velocities around 2800f/s and a model 70
that likes to go as fast as possible.

I've loaded for at least 4 different 270s. All grouped very well with the same heavy load (can't remember the amount off the top of my head) of IMR4831 and a 130.

Q,
I shot a lot with these Sierra 130grainers in my 270's. My best results came from H4831sc, 60 grains, bullet jump 015 to 030". VV 165 also is excellent.
For the TSX the story gets different. My best jump here was about 060".
By the way: stop praying, believe in yourself!
Nice day,
Jan

To further complicate things, I've found that in my .270, different bullets of the same weight but different manufacturers may like different powders.

For example, I'd worked up loads with IMR 4831, H4831sc, IMR 4350, Re 19 and one or two others with okay results. But 49.5 gr IMR 4320 shot Sierra's 130 GK very accurately, and Speer's 130 BT, and Hornady's 130 SP nearly as well, all of them being better than I'd been able to do with the other propellents.

But then I got a load of 130 Nosler Solid Base bullets, and 49.5 gr. IMR 4320 wouldn't shoot them worth a darn. H-4350 did much better, and H 4831sc (59.5 gr) produced really great accuracy.

I guess the bottom line is, you just have to jump in and see what works for you.

Having said that, H 4831 is the classic propellent for driving a 130 grain bullet in a .270, and I'd start there (or H 4831sc), if I were you. Then, try Re 22. After that, I'd recommend IMR 4831 or IMR 4350.

For a long time the various 4831 powders -- Hodgdon (both the old surplus and the present newly-manufactured versions, as well as the SC version) and IMR -- have been considered the ideal powders for the .270 Winchester for bullets of 130 to 150 grains.

I think that RL22 (Alliant's Reloader 22; I understand that it's the same as Norma Magnum Rifle) is actually somewhat better than the 4831s. RL22 gives me equal or even better velocity and better accuracy.

If you also load for the .30-06 or .308 you might want to consider this:

RL 22 is, I think, a bit too slow-burning for the 30-06, except it works well in highly compressed loads with heavy -- 200 gr. and heavier -- bullets. I think you cannot get enough RL22 in a 30-06 case to cause an overload.

The best powder I've found for 150 gr. bullets in the 30-06 is IMR4064. IMR 4064 also works well for all bullet weights in the .308 Winchester. For heavier bullets in the 30-06, I like the 4350s (H or IMR), H414, and the 4831s.

If you want one powder for everything, you can't go far wrong with IMR4350. It won't give top velocity in the .270 but it will often give excellent accuracy. It works well with all bullet weights in the 30-06, and it works for the .308, especially with heavier (180 and up) bullet weights.

I used 60 grains of AA3100 and CCI 200s behind Sierra 130-grain Pro Hunters for several years. I eventually soured on the bullet's performance and went to Speer Grand Slams with the same powder charge.

Shot my 270 for many years and always have loaded,and loved H4831-59grs.

IMR 4064 may be appropriate for a gas-operated autoloader because of the need to keep port pressures down. However, in a bolt rifle, somewhat slower powders will provide more velocity at acceptable pressures.

As others have said, 4831 is the classic powder for the .270. I would caution that the equally classic "Jack O'connor" load of 60 grains of SURPLUS 4831 with a 130 grain bullet is too hot with some guns and sometimes excessive with the slightly faster versions of 4831 available today. For example, my Sako tops out with 58.5 grains of H4831, which generates an eye-popping 3200 fps from its 24.4" barrel.

RL-22 (Norma MRP) is an excellent powder with a similar or slightly slower burning rate to 4831. The main drawback to it is that it can vary greatly from lot to lot, so if you use it buy enough of one lot to last you for an extended period of time.

I've loaded for 3 270's and had good luck with H4831 for the 130g bullets. I'd start with 58-59 grains and move up as the conditions warrant. I've used 62.0g with the W-W cases for around 3125fps out of a 22" tube. The W-W cases seem to have a little more capacity. This 130g load is excellent on deer, antelope and elk. Good Luck

You absolutely cannot go wrong with any of these:

H4831SC
IMR4831
H4350
IMR4350
Re22, Re19
AA3100
VV N160

I've had excellent results with each and every one. The various 4831s with the 270 are like peanut butter and jelly.

For the 5 270s I load, if I had to limit myself to 2 powders it would be H4831SC and Re22. Stick with Hodgdon powder if you're worried about temp sensitivity.

I use R22 or H4831 with all bullet wgts in my 270. I`m sure there are others but these have been the "go to" powders for most of the 270 shooters I know.

I load for 50 or 60 cartridges, and have only take the 22" 270 to the range once. 130 gr and 51 gr of bulk IMR4895 that is as fast as H322 did 3092 fps and jammed the bolt something awful. I should have taken a mallet.

48 gr did 2814 fps and 1.4" 5 shot group at 100y.

I need to try a slower powder.


TEANCUM [I hope that is not his real name] is getting 3125fps with 62 gr H4831. I should try that.

That's quite a bit of powder. My bro shoots 57.0 grains with a 130 Btip and is as happy as a puppy with 2 peters.

I like RL-22 with both 130's and 140's.............DJ

Some rifles seem to like a lot of H-4831, others don't. But, I am not sure it is all in the rifles...it might be some differences in powder lots too.

I use 61.5 and/or 62 grs. H4831 (the original stuff from the late 1950's) in my Winchester M70 .270, in W-W brass, with WLR primers. It shoots sub 1 MOA at 200 yards (that is, sub- 2"), and chronos 3,189 fps across the Oehler. That's why I keep the gun AND the powder. (Am now down to less than 8 lbs.) Those are the OLD Hornady 130 gr. spire point bullets I'm using, BTW. Have slain both a few mule deer and an antelope or two with them.

Having said that, I have had other .270 rifles that topped out at about 57.5-to-58 grains of 4831 too.

I'm a little surprised no one mentioned 4350. I usually shoot 4831 but have shot a lot of 4350 in various calibers of that case size.

On my brother's rifle, I do not know if the 57.0 grains is anywhere near topping out. What I do know is that day at the range, when he shot 10 rounds with that charge, he shot 1 fouler and 3 three shot groups. Where the largest group was 0.523 and the smallest was one itty bitty hole.

uhhhh, you didn't read the thread very well did you?

Qtip, what Doc said for powders. The Re 22 and H 4831 SC are 2 of the best in this caliber.
Whichever you choose, do as you stated and work up from lower, anything over 59 grains is getting up there, go slow!

Like DJ, Re 22 works really well for me, but I have more 270's with accuracy loads that are on H 4831, both regular and SC.

Good shooting!

Fish, you get that PM on the barrel?

Doc, roger. I sent a quick reply--hope you got it, look forward to seeing it--D.

I purchased way to many .277 130 Nosler Balistic Tips when the pro shop was nearly giving away the seconds early last year. So I've been playing with them this year and here's where I ended up.

Yesterday over the chron...

Savage 112 22"
Win brass
210 Federal Primers
130 Nosler Balistic Tip

59.5 H4831 SC 2950 fps
55 IMR 4350 3000 fps

Both sub MOA

Thanks for the quick responses and feedback, i really appreciate it. Having not experienced handloading for the 270 i just needed a good place to start in reference to which powder to use for this caliber and you all provided that. I have all the powders on hand thats been mentioned (IMR4350/4831/4064/7828/RE22/19/15) with the exception of H4831 & H4831sc. I think i'll start with IMR4350 and IMR4831 and if nothing looks promising there i'll give the RL22 a go. I'll also pick up a can of H4831 to have on hand because everytime i read something on the 270 Win that powder seems to be the first one to surface.

Just a side note: All my reloading experience is with bolt action rifles and this 270 is a Browning Bar auto. Is there anything i need to look out for other than making sure that the bullets are seated deep enough that they will fit in the magazine? Again Much Thanks to everyone! Mike

Yes, get a "small base" full length resizing die. You may run into feeding problems with a standard full length resizing die.

Doc,
Man i'm glad i asked that question. I really appreciate the heads up on the dies. I called Midway and changed my order to the small base die set. Thank You! Mike

H-4831 or AA3100

no problem. You'll be glad you changed your order.

H-414 is all you need for the 130gr in a .270

I just wanted to give a little update in reference to helping my neighbor find a good load for his Browning Bar .270 and the 130gr Sierra Pro Hunter. I tried several different powders that you guys recommended and got the best results with H4831. The RL22 shot good and the IMR4350 also shot very well but the H4831 shot the most consistent and tightest groups. We're well pleased with this load and it should do a fine job on deer. Again Thanks for all the imput! Mike

That's great Qtip, now get your stands in the right place and go get 'em!

Can you say, "dead deer?"

Good shooting! I think your friend will be quite happy.

Yeah, I'd say you stumbled on to one heck of a load. That accuracy will rival any Bolt gun on the market and beat most of them hands down!

H4831 was made for the good ole' 270 win. I'm loading that same charge under some 150 NBTs for a 270 WIn BAR and it does well with that load. Talk about slam a whitetail, those 150 NBTs are plain mean in the 270 win

Good Luck and Congrats on the killer load.
