Whats your favorite powder for 270 win?
I'm using H4350 I'm under MOA with my groups at 53.4 gr and berger 140 VLD 2930fps.
 
I have been using R-26 recently. I can get 3050 fps with 150 Nosler Partitions and 3100 with 150 LRAB. Accuracy has been very good also.
 
It all depends on bullet type/weight and rifle reloading for,
right now my stainless Ruger 1B gets

63.0gr of W760 with 85gr Barnes TSX @ 3775fps (pig load)
54.0gr of R-17 with a 130gr Hornady SST @ 3075fps (deer)

I used to have a Browning A-Bolt that preferred H4350, I have also used R-19
(but I have a ton of R-17 and W760 right now.....so).
 
My current load is with IMR 4831 in a 22" barrel pushing 140 SSTs at 3050fps. I worked this load up some 4-5 years ago with I was only about 14 so I am going to revisit load development and see how it does with other powders. The IMR 4831 use to do really well in it, but it is a little temp sensitive. Anything in the 4350 to 4831 burn rate works well with the 130s and 140s. With the heavier pills such as 150s+ then I think you should start with H4831 and work up through 7828 and H1000. gun)
 
58 grs of RL22 in my sons 24" Rem 700 gets 3060 fps with sub minute accuracy. Got lucky, first load I tried :)
 
When my Remington 270 was still a 270, I used H4831sc with 140 grain Accubonds. I didn't have a chrono at the time, so I'm not sure about speed. But it was very accurate.

RL22 did well also.
