What rifle did you end up going with? I had a Tikka T3 in 270 WSM for a couple years - I really enjoyed the cartridge, but switched things around and went with a 6.5....
Anyways, I found good results with RL-22 and Fed 215 primers. My rifle shot 130 TTSX, 130 SST and 140 Accubonds with very good results. RL-22 shot so well across the board, I never bothered to try another powder. I've heard good things about H4350 as well.
I only hunted with the 140 Accubonds and they worked well (although both shots were only about 100 yards, so I have no input on long range killing power- it knocked the snot out of 2 black bears in no hurry). I did take that load out to 600 yards on steel and it seemed to put the bullets pretty dang close to where I wanted them to be. Not too shabby for a sporter barreled T3.
Anyways, I think you'll enjoy the 270 WSM!
