Gonna be reloading soon for my first 270, a Rem 700. Be starting with couple of the 130 & 140gr bullets. I already have some Reloader 17 that I will try. I'm going to for sure get some 4831. Is there a noticeable difference between H4831 and IMR4831, and also the SC??? If so I'd like to spend the $ on my best chance selection!

You may not need to try anything else after the RL17.

If you try 4831, I would opt for the Hodgdon. SC not that important.

I use RL 17 in mine with 130 Federal Fusions at 3200fps. I run H4831 with 145elds in another. I think youll be happy with either selection but I lean RL17 more.

H4831 and H4350 both shot well with 130s out of mine (Rem 7600), but rifles are very much individuals. My uncle has an identical model rifle, and it shoots both of those powders terribly, but is a tack driver with H414. A lot of it is just luck and listening to the rifle.

H48831 has worked very well for me in any 270 I’ve used it in.

H4831 for me too...IMR 4831 worked good also

My Kimber 84L 270 loaves 55.3gr H4350/Barnes 129 LRX. (RWS cases) I've also had great results with IMR 4064, IMR 4350, H4831, R26. I never tried R17 in it as at the time I was also workign with a 300WSM and R17 was "magical" with the 168 TTSX, ha

My current and more than a few past 270s of mine liked IMR 4350 with 130's.

I've always used IMR 4350 whether the bullet weight was 130 0r 140.

In one of my 270’s with Nosler150 B/tips, H4831 and H4831SC gave practically identical velocities and spreads but the SC version gave groups at each charge level that were 2 - 3 times larger than H4831. So if one doesn’t work you may want to try the other.

H4831 or rl22

H4831 is the classic. SC is the same but meters better. Trouble is finding any.

RL26 gives great velocity with 150's, maybe harder to find than H4831.

Hunter is also good in the 270 and may be easier to find.

57grs of IMR 4831 with any 130gr bullet has always been a accuracy sweet spot in any of the 270wins I've loaded for.

Reloder 16, 19, and 22 have been good powders also.

Thanks everyone, you've pretty much confirmed what I thought! I'm definitely going to start with the RL17 I already have, and gonna try get H4831 for the same test. I already have 4064, it's my best powder in my 30-06, to try if the results of the first 2 aren't good, but suspect I won't have to look any further. But if I do, I'll save this thread, and I'll have ideas where to go! I'll eventually probably try some 150grs in it, but not to start. My 30-06 covers all that good enough. I hunt whitetails, and most shots are inside 100yds. Most, but much longer can happen!
4350 sure seems to do well, so I may go ahead try it!

H4831SC definitely reduces the crunch when you drop the powder and flows better if you’re using a basic hopper dispenser.

56 gr. IMR 4831 with 130 gr. bullet works well in my 270.

RL22

I use 55 grains of IMR 4350 with a 130 ballistic tip or a partition, over 40 years now.

For 130's mine likes IMR4831. It doesn't meter worth squat but since I only use it for hunting it only gets shot a few times a year. For ELDX's it really shines with unobtanium (RL26).

I have been shooting the 270 Win for decades and have always got the best accuracy with H4831 with 130-150gr bullets. I have tested other powders along the way but always came back to H4831.....................until I tried RL26 !!!!

Try RL26 and a 150gr BTip or Partition and you will sell that .06

I will try RL 26 first chance I get!

Lots of good advise here.
Myself, it has been my most useful chambering for decades . Until Alliant came up with their new powders and so many great new bullets came on market, I was fairly traditional. I used the 4831's, 4350's etc with much success. I seldom use them now because Reloder 26 and 16 have displaced them.
Reloder 16 on the 130's and 26 for the heavies, it is amazing stuff. Bull Elk are the baseline game animal here and I prefer the Nosler 150 gr Partition over RL 26 and the Hornady 130 gr GMX/ RL 16.
The 150 Partition @ 3030 fps from a 22" barrel is a great first choice for Elk and Moose, imo

I already have 150gr BT's on my list. I'm looking forward very much to heading down the road with this 270. I was one those who before I began reloading, had the 270 isn't needed attitude. Until in recent years, some friends who have been through it, have made the same comments about getting rid everything else! No way I'll get rid my Tikka M65, made in 1975. I dare say it's in the top 3 of THE BEST rifles ever made! I'm shooting 150's with it in 1/2" several times @ 100yds, with A4064. But I got the feeling I got another jewel in this 700. I cleaned it good yesterday. It's in 98% condition IMO, inside and out! I'm Locked & Loaded with my 06 for deer season soon to come, so I probably won't start shooting the 270 until after 1st year, hope I can wait that long??

What is you'll best load and avg velocity using Rel 26 & 140's, 150's?

I’ve only used IMR4831 to this point; but I will be switching to H4831SC soon. I think I can get my groups to closeup a little more with the H4831SC, than I can currently with IMR4831.

Been using RE 19 for years with 130 gr. pills. Accurate and good velocity. YMMV

IMR 7977 is also a great choice for the 150s and temp stable.

The two or three 270's Ive had preferred 150 gr bullets and RL22 powder.

is anyone running R26 with 130's? If so what kind of velocity are you getting?

Mine is boringly accurate with the old standard 60.0 gr H4831SC, CCI 200 and any 130 grain bullet seated to the right length. There is a noticeable difference between the 4831s. Mine likes IMR with 150s.


Good luck, Old70

An easy 3150 in my P64 Featherweight with 130 grain Tipped Bear Claws.

Dandy rifle right there Beretzs!

I have since switched it up to an S&B 6x42 since it’s mainly a deer rifle and from 0-400 the #4 reticle is great in the woods as well as a little longer poke. The old M8 Leupold worked okay, just lacked a little on dark days.



The rifle with the S&B

Nice, and set up just right for where I hunt. That's a hunting rifle indeed!

^^^^^^THIS^^^^^^
RL16 on the 130s......I've used the 4831s for 50+ years but this RL16 has em beat IMO.
The RL26 for 150s and 160s gave exceptional performance.

I

Thanks for the info. I am getting 3067 with IMR 4350 and NBT 130's. I know R26 is "magic" with heavier bullets but was not sure what it would do with lighter ones. I know ever rifle is different but if everything held true it looks like about a 78 FPS gain to switch.

It’s my go to for the woods sits.

I have 10 or 12 boxes of those. I need to try some, see how they shoot in 270’s, 270 Weatherby and 270 WSM’s. I shot a lot of the original Bear Claws years ago. I think Jack Carter would have liked the tip on his bullet.

Another vote for H4350 👍

I'm probably the only guy on the planet that would be reaching for 4064 and a 140 gr Ballistic Tip, for a 270 hunting round.

I think they’re great hunting bullets. Brother and I have been doing real well with both the 130 and 140 version.

I don’t know if I gain much over your load for hunting but I just wanted to try it. Bob said back in the day he used some RL25 and got good speed so I decided to give 26 a whirl. Works fine but I’m not sure I’d monkey with it if your 4350 load shoots great.



Nope you aren’t the only guy. Usually with any new 270 that’s the first load I’ve tried to see if the gun would shoot. Usually it’s a 2900 FPS load and with excellent accuracy in any sorta straight rifle.

Seafire, I ain't frowning at it. I found out how good it is in 06, after I found out how great it is in 30-30! Very consistent stuff from every perspective! No speed demon in a 30-30, but everything else A+

I have found over the years of loading for the 270 Win. that with 130's several powders work very well 4064 being one of them. 4064 just never gave me the speed I was looking for but I tried it more than an a few times.
My go to powders are IMR 4350 and IMR 4831. They just seem to give me results without a lot of fuss. I have also tried several of the R series of powders, just got better speed/ES/SD with the two IMR offerings.

I did try R26 with some 150's and got very good numbers with it but did not like the recoil of the 150's vs 130's. I have killed a lot of deer over the last 45 or so years with 130's so I don't feel that I am leaving anything on the table using them for whitetail and mule deer.

For 130 gr bullets, I'm now using IMR 4451. For 140 gr, I like RL 16.

[i][/i]

+1. Three M700s shot lights out with RL22.

My 270’s & 280’s do fine with RL17.
IMR4350 and RL22 are just as good.
No flies on the 4831’s either.

Three shot groups back to back. The Old 270 is just damn hard to beat… I don’t care who ya momma is! 😆

Damn nice Gunnut.. that RL17 load is a good one too. Pretty much a 3050-3100 load and usually quite darned accurate, as you’ve shown!



Not as nice as yours, but I blame the Leupold

This was 3 groups with 26 trying to get the old friction dials centered up.

Thank ya sir!

Mighty fine shoot’n B! That’ll put meat in the skillet every day and twice on Sunday. 💪
And your right on the money. Seems like it was 3079 fps average.

I stumbled on that load with ‘17 right out of the gate with that Winchester, very first load I tried. The rifle is bedded in a low comb stock which I’m not crazy about but…. If it ain’t broke-

I’ve got an extry MCM Hunters Edge I’ll drop it in and see how she acts. Every time I get wheels balanced & rolling under a Pre’64 I’m impressed.

You’re damn right buddy. Ain’t much better than Hunters Edge on a P64 in my book. Unless it’s a Legend.

Rick Dredge uses the 17 load a bunch. Seems to be good in multiple guns.

You'll got me, Biting at the Bit to get my 270 going. Nice!

Thanks Beretz.....2900 fps is just fine by me.... to achieve the equivalent point of impact of faster 4350 and 4831 loads, all I have to do is raise my scope elevation by two clicks and I am right there... but 4064 never fails to be accurate unless something is really out of line with the rifle...

but that load, and the rifle being a Model 70 Sporter, and the scope on top being a Leupold 3 x 9.. the world just seems all in balance....

same bullet and change the powder charge to 30 grains of RL 7 or 4198, makes the 270 a very light recoiling rifle quite capable of dropping any deer on the planet at 250 yds or less.... with a little practice 300 yds is real do'able also....

beretzs, here's a comparison with my M70 supergrade with 24" barrel using RL26 with the 130 TBT. 61. 0 grains (top), average was 3157 fps. With 62.0 it was 3227 fps. i have RL17, haven't tried it though. Great rifle and buck too BTW!

Sounds like we were running pretty close on speeds, especially taking into account the extra barrel you have. And thank you!

Yep that's what I was thinking. Hard to beat that combo....I'm just glad I grabbed a bunch of the TBTs when they were around $24 a box!

Man, you aren't kidding. Rocky Mountain Reloading had a slew of 130 pull downs and I only got 250 of them. Wished I had gotten a 1000 of them little devils. They're accurate and when they were even 24 a box were a steal. Live and learn I guess.

I haven’t read the entire thread yet, but H4831 is one of the more temp stable powders out there, whereas IMR4831 is not particularly stable. I have roughly 4K rounds of chrono data going back to the early 80’s with 270’s, the majority with H4831. The pre-Extreme powder produced 50-60 fps higher velocity than the current H4831 in 270’s.

Depending on which lot of powder, RL26 produces 100-175fps more velocity in the same 270’s, using the same brass. RL26 is not quite as stable as H4831, but velocity loss is small, and the loads shoot to the same POI.

I use regular cut because that’s what I always have used. When I tried H4831SC it was a bit faster burning, at least with that particular lot.

Along with the RL17 I already have, H4831 is for sure my first tests. I'm gonna try RL26 somewhere down the line, maybe few others. Seems 4350 is very good in 270 & 30-06 so I'll probably get around to it also.

Me too………

Given the current situation, I would snatch up whatever powders suitable for the 270 I could find.
RL17, H4895/4350/4831, Big Game, Magnum, and some of VV powders are temp stable, too.

Accuracywise, H4831 and N165

Speedwise, Magnum and N560

Many powders I have not shot, though.

I'd agree....it's not hard to get a 270 to shoot well enough to hunt with a number of powders.

4451 worked well for both in mine (130 -140)

Scotty mentioned that I am using R17 with 130’s. Manufacturers data shows maximum of 54. I use a little less and if it doesn’t shoot well then it’s a rifle issue. Have had same success with IMR4831. Those are the best for 130’s.

I also like R26 with 160 NP’s. If those don’t work you need a 375.

My Barnes manual shows 59.9 grs of Rel 19 with the Barnes 130gr TSX/TTSX gives 3211 from from a 24" Bbl.. My chrono shows 3219 fps with this load , superb accuracy & not the slighest sign of pressure.. I worked up slowly & was amazed at how this powder performed. Bullets seated .050 off the lands. Perfect.

In three different 270s with 130 and 140 grain bullets I've gotten my best accuracy with H4831SC. I used RL 17, IMR 4350, H4350 in all three as well with OK results but not anything like H4831SC. Reloader 26 was great for 150s. 61 grains gave 3000 fps with acceptable accuracy but not stellar accuracy. H4831SC was more accurate than RL26 as well with the 150 partition although velocity was closer to 2800 with what I considered to be a near max load.

IMO H4831SC is hard to beat in the 270 for 130 to 150 grain bullets. I would be curious to try RL23 at some point if this ammo components shortage ever gets sorted out

I agree with you for the most part, I have tried many powders over the years in several 270's and H4831SC has always been the accuracy king in every one of them..............I fell in love with RL26 because I can honestly get 200fps more velocity out of the 140-150gr bullets I have tried.....but not with quite the same accuracy.
The original H4831 that was around before the short cut version and the "EXTREME"era I think even worked better.

The 200 fps increase is mighty hard to ignore. I never tried RL26 with 140s, thanks for the heads up

I haven't had as good of results with H4831 (def good enough to hunt) in my rifles like I have with a few other powders;for some reason. I too would like to try RL23, if I ever see it on the shelf.

RL26 is magic pixie dust in the couple 270’s I have tried it in, giving best accuracy and velocity. I use 61 grains with 130 grain bullets and 59 grains with 150’s. Pretty much settled on the 129 LRX at 3100 FPS.

My only complaint is it turns a measly 270 into a slightly obnoxious outfit. For this reason, I also like to launch 130 interlocks at 2800 with H414 for my home state whitetails. They haven’t been able to tell the difference.
