Which .270 powder?

If you dont have the recommended powders yet look at H4831. In may circles it is the ultimate 270win powder. I run right at 59 grains behind a 130 grain bullet, but I use the short cut version (H4831sc). You wont get top velocity out of varget, but you may get good groups.

Can't go wrong with H4831 or the sc version. H4350 works well with 130's, and I'm having really good luck with the new IMR 7977 under the 140AB.

I get 1 hole groups with H4831SC out of a Tikka and Accubonds.

H4831, H4831, or H4831

I've used IMR 4350 along with Nosler Accubond 140gr bullets to great effect. At 100 yards; don't know what the shooter did with that one on the left. Maybe he jerked when he pulled the trigger. Or maybe he just is a jerk.

Pick a proven powder & play with AOL a bit .

The first bottle neck I started reloading was the .270 win., and that was over 30 yrs. ago.

As far as powers and bullets also, I prefer the slow burning one's. Slow burner's are easier to obtain higher velocity and better accuracy with, land with significantly less pressure spike issues.

As for powders, I've had excellent results with RL22, RL19, IMR-7828, IMR-4350, H1000, and H4831 have all been very good performers. But as with any reloading endeavor / development, the rifle will often dictate which powders will perform best for you.

FYI, when reloading for bottle neck bolt guns, metering isn't really important, nor is it the best approach. Most who reload for bottle neck, and specifically when it applies to bolt guns and auto loading actions that shoot common big game cartridges like the .270 win., it's most beneficial, thus recommended that charges be individually weighed on a scale, not volumetrically thrown.

As for bullets, and regardless of what chambering, if it's for hunting big game, I've yet to use a bullet that performed better than the Speer Hot Core. They've been very effective and accurate in every chambering I've used them in. They're just a great bullet, and they don't cost an arm and a leg either. We killed 4 deer last week with them, all.270 win., and all were clean through and through heart lung shots, with the only exception being mine, in which I choose to shoot him in the neck, which was due to the extreme up hill angle he was at.

I have been reloading for the 270 Winchester since the early 1970's and the 130 grain bullet is by far the best bullet weight for the 270. I have had great success with the Speer HotCor, the Speer boattail, the Sierra boattail, and the Berger classic hunter. As for the choice of powder somewhere between 55 and 56 grains of IMR 4831 has always been a good choice. The commercial companies loaded between 53 and 55 grains of IMR 4350 and that is also a good choice. Lately I have been loading 52 grains of Reloader 17 with the Berger Classic hunter bullet and it is very accurate. The 270 Winchester is an easy cartridge to load for and the rifles easily shoot less than minute of angle with good loading practices.

IMR4831, IMR4831, IMR4831, oh did I mention IMR4831

Has anyone mentioned H4831 yet?

Jack O'Conner had it right with H4831 & the .270.

I'm a big fan of IMR 4350, used it in .25-06 and .270 both with good results.

Gonna chime in 5th or 6th or maybe 8th for H-4831 and a 130 G bullet. I've played with a few other powders that worked pretty well also. I have used Sierra Game kings with decent results. At close range they pass through like a pencil. Hope to pull the trigger with Bergers next season and stop tracking so much.
Also have to agree with Gamestalker. While working up these types of loads for my bolt, I measure powder 1 case at a time.
