Home Forums Reloading Big Game Rifles Best powder for the 270 Win??

RL15 will work very well if you want very low recoil and about 2850 or so with the 130 grain bullets. It works very well with the new 110's. For highest velocity with the 130's go with H4831sc Extreme first and then try RL22. I prefer the temperature stability of H4831sc Extreme Series so it is always my first choice. It also works well with the 140's and 150's.

Altho H4831
Winchester casings
CCI 200's or Winchester 120's
and Speer, Hornady or Sierra flatbase 130's always worked well when first exploring a load and and new-rifle accuracy-potential.

I later learned to really like Nosler and Hornady 140's as an all-around weight.

BTW, Nosler 150-Partitions penetrate every bit as well as .30 cal 180-Partitions - for elk!

Magpro gave me 3200 fps using a 130 TSX or Sierra GK and a couple of one hole three shot groups.

OK here is someone else that mentions RL22 and temperature stability! I have a great max load of RL22 + 130 Nosler AB load but was worried about temp stability! Regards the 110 grain bullet and RL15, I cannot see the advantage in that load.

Prdator did a test with RL-22 and temperature stability. It was as stable as any other powder in his test. Early lots of RL-22 were slightly more energetic also. I think that they tweaked the powder and made it more temp stable. I wouldn't worry about it............................DJ

I use RL22 and H4831(standard). If a 270 does not shoot with one of those,the rifle is unlikely to do well with much of anything IME.Other powders that have done very well are 7828 and RL25.Magpro was accurate as well.

The RL 15 load is a good and very useable if a guy is into making the 270 a 7x57 or 7/08,or wants 2900-3000 fps with a 130 and less muzzle blast.

IIRC,Jack O'Connor's early hunting with the 270(including moose and grizzly) was done with 49.5 of 4064 and 130 gr bullets.RL 15 gives similar results,no doubt.

I have had excellent results with H-1000. H-1000 has given very very consistent loads in the 270, 300 Win, and 338 Lapua

Good choice, propably won't have to look any farther ..

H4831 is synonymous with the .270W, like bread and butter! Bacon and eggs!

But go with the shortcut version (H4831SC), as it meters quite well!

I have gotten a little better velocity and accuracy with 130s with IMR 4831 in the .270s I have loaded for over than H4831 or the either of the 4350s. But they are all well suited to the cartridge.

280, No doubt they are the classics for the venerable round.But there are others up to the task.

I've been burning H4895 (on my 3rd 8lb jug) in one of my rifles.

IMR 4064 has been a top performer in the accuracy dept. in another.

I have used IMR4831 but the pressure jumped when I used it at 90 degrees on an antelope hunt so I dc'd it. Same with RL22. You can load H4831 sc E to the max and not have to worry if it is hot outside. The RL15/4895 load is great for youngsters and others who don't like recoil. Good option for those who neither need nor want max vel. That load beats or equals the 257 and 7-08 and has very low recoil. When I was 12 the oldtimers used 4064 with the 130's.

Joe,

IMO, RL15 is too fast........for me, I've had best results with Norma MRP, RL22 & H4831, in that order with 130 & 150 grain bullets.

Prior to the introduction of the old 4831, 4064 was the slowest powder available to the cannister trade.

It's stil a good but not common choice. As with other things in our lives 4064 has fallen to others best suited for the application.

I have a supply of the old army surplus 4831 (also know as 4350 DATA)and its the stuff that O'Connor used for those awesome velocities. Nothing today can compete with it except perhaps the new "enhanced" factory ammo....

H-4831, IMR-4831, RL-22 are all good powders and IMR-4064 is still a great powder in the .270. it is mild of recoil, muzzle blast, and vel. is right up there.

I am thinking about that 110 grain load + RL15. I guess I always thought the 130 - H4831 load was a light kicker, maybe when I am 20 years older I will change again, but man it seems like a pussycat after I shoot a light 300WSM with 180s near 2900 fps.

Ray, I remember my dad, back in the 50s, along with a couple of buddies buying the old 4831 in 100lb. lots at a time.

Slow ????? just fll an '06 case up to the mouth and go shootin'.

I will go along with the others that said H4831 (I prefer short cut) is the powder of choice for the .270. It works exceptionally well with 130s-150s and is certainly a good place to start. I have had good luck with other powders, notabley RL19, RL22, IMR 4831, Ramshot Hunter, and Accurate Magpro. Never tried RL15 as I think it is a bit fast for anything but light bullets in the .270.

I use IMR 4350 powder and a Barnes 130 bullet

The wheat found in Egyptian pyramids that is reportedly viable has nothing on this thread!
