I have been loading .270 Win for about 25 years for my factory Rem 700, 22" barrel, and have recently been experimenting with some new loads.

My long-time load is a Hornady 130 gr SP over 56.0 gr IMR 4350 at 3060 fps.

I could not get a 130 gr SST to group well.

A Nosler 150 gr Partition over 54.0 gr IMR 4350 gives me 2930 fps, with marginal accuracy.

I am tweaking a new load with a 140 gr Accubond over 55.0 gr IMR 4350 at around 3000 fps that groups well.

As always, every rifle is different. I could not get good results with RL-22. My go-to powder for several calibers is IMR 4350.

I use H4831SC for my 270s. I have found very good accuracy and performance using 130gr Ballistic Tips for deer sized game. I never put the Accubonds to meat, but accuracy was about the same.

Winchester brass and primers, shooting IIRC 3160fps from a 24" barrel with a moderate load.

I used R 19 pushing 140 gr Barnes TSX. I got about 3100 fps out of my 26" Remington Sendero.

Initial results now that I got my rifle back with new stock,

I can get .5" with a 140gr accubond over 57gr ADI AR2213SC (H4831SC equivilent I think) at 2941FPS average, groups opened up for the 2 powder charges above that that I tried, but there were no pressure signs so I will load some a bit hotter and see what sort of velocities I can get, hopefully something over 3,000 will group

Re: .270 winchester

H4831 60*gns
215m primer
130 serrias or Ballistic tips
in winchester brass 3212 in 24" vangard 3155 in 22" M70
ES under 25fps from summer to Deer season
The 130 grn bullets are better than 1/2"at 200 yds as long as you want to shoot.
I have another load with the same set-up but only 58.7 grms of H4831 and the 150 Ballistic tip This load has an ES under 15fps so far ( I have only shot 11 shots). I found that the H4831 gets closer ES once you "arrive" at the max back off 3/10ths of a grain and play with the seating depth. I'm loading to over max loads so please start 3 grains lower and work up
I have yet to see a 270 not shoot H4831 near top velocity poorly. I worked up loads for a shop years ago in Vt. All the hype in print and now on the net has yet to prove that wrong. If your looking for velocity and accuracy in a 270 try these loads. The low es and insensitivity to temps are going to make a great long range load.

I tried Reloader-22 and IMR-4350.The IMR-4350 gives me the tightest groups and around 3000fps with 130gr Hornady SP.My Remington 700 just does not like a boatail bullet.Groups 270 Win. 4 shots 100yds on Flickr - Photo Sharing!
