I've been reloading for a while now...but I finally got around to reloading my .270 WCF. Looking for any suggestions on powder. I currently run W760 behind a 140 grain accubond. I average right at 2950 FPS. I can push them a little over 3000 but my SD and Accuracy load is 53 grains which is the book max. I got up to 55.2 without pressure signs but accuracy and SD started to suffer. I've heard RL22 is a good place to start as well as RL26....26 however being the Unicorn powder right now and has been for quite some time. Any suggestions? Thanks!!!

I have always used IMR 4831in my .270 with the 140 grain Hornaday interlock. Velocity is right around 2900, and groups are close to 1.5 @200 yards with my Encore.

Ive found 58 grains of h4831 and a 150 grain speer bullet over a 215 fed primer in several 270 win chambered rifles to give excellent accuracy
under 1" 5 shot groups off a bench rest at 100 yards consistently, and about 2940 fps in my browning and sako rifles
while Ive only used it on mule deer its proven very lethal, even out at nearly 450 yards on one occasion

some older reload manuals list 60 grains as max, I see no pressure signs but ,
58 grains is the max the case allows and still have the bullet seat to the correct depth.
Id start with 55 grains and work up just to be cautious, and as always cross check at least three reload manuals

My favorite load for my 270 is 54 gr of IMR4350 under a Nosler 130 BT. This load shot great in every 270 that shot it. IMO IMR4350 or IMR4831 is hard to beat in a 270 Win

Standard load for me for over 40 years , has been 56gr IMR 4831/130gr/Win or Fed brass and Fed or CCI large rifle primer. Truckloads of moose,deer,elk,black bear and antelope.

I too use IMR 4831 with the 140 grain Hornady bullet. I get slightly over 2900 FPS out of my 26" Encore barrel with groups averaging around 1.25-1.5 at 100 yards.

you can't really have many issues with H4831 or IMR 4831 but I prefer the 150 grain speer bullets in a 270 win.
btw Ive also used a speer 200 grain bullet over a stiff load of H4831 in a 30/06 browning BAR,
with a 215 federal primer, on mule deer, it no more or less lethal, and it kicks a bit harder but , I'll point out its also been a consistently accurate combo!
most of these discussions are rather pointless as its the skill of the user and his knowledge ,and acceptance of,of each rifles accuracy and range limitations, and the projectile selected, rather than the cartridge that makes or breaks the combos effective use!
the one attribute it does seem to have is its use
(200 grain bullet/300 win mag/ BAR) irks my hunting buddies,
if I use it on mule deer, but not so much on elk,
I find it amusing, and a bit confusing, in that I don't really understand why my choice in rifle or handload combos,
can in any way effect them. but if you lack a reason to start a heated and pointless conversation, tell the guy next to you you have a 300 win mag in a bar you intend to use on mule deer hunts..... its always resulted in a pointless and sometimes mildly heated discussion... I don't really know why, it works well, and if you place shots in the lower,. heart/lungs its been very consistent/lethal and does not destroy any more meat than the 270 150 grain combo does in my experience.

I've been using 760 for the last couple of years with a mag primer. Shoots really well in both my 270s

Any difference in performance with the H4831 and the 4831SC?

from my limited experience, the main advantage of h4831SC, is you MIGHT be able to get a bit more dense or heavier powder charge, without needing or overly compress the powder charge, I have generally found the 4831 SC gives a smidge higher velocity with similar charge weights but that could easily be because much of my older h4831 is over 40 years old,(yes it still works)
most of the younger guys won't remember but H4831 use to be sold in gallon jugs
I vaguely remember paying about $60 a gallon

BTW WW760 also works as pointed out, above, but at least in my area its been a bit harder to locate.
