Accurate Arms powders in 270 WSM?

I was thinking about picking up some AA Magpro, 3100 or AA4350. Curious if anyone has any recommendation on these for 270 WSM?

My son prefers Magpro with Nosler 150 gr Ballistic Tips in his 270WSM, while I prefer Accurate Data 86, a non cannister version of 3100 with the 150 gr bullets. FYI, Accurate 3100 is no longer being offered for sale by Western Powders, Accurate's parent company. With 130 gr bullets, I like Reloder 17, while many people believe the new Reloder 26 to be the holy Grail for Magnum cartridges, short or otherwise. I haven't tried it yet, since I would like to use up what I have on hand.

I have used MagPro in my 270 WSM model 70 shadow under the 140 gr Hornady BTSP. Very accurate, anchors deer very quickly, but make sure you start low on the charge. My max charge was a full 2½ grains under the book max.

3100 not only has been dropped from the Accurate line for some time but the one remaining new, unopened container of it I had started to break down last year. The nitric acid scent was powerful and is what sent (or should that be scent) me looking for which jar on the shelf was responsible. It wound up mixed with the regular lawn fertilizer and spread on the lawn.

If you've got an old container of 3100, I strongly recommend checking it for signs of deterioration.

I've now got a collectible plastic power jar, I supposed. Should fetch at least 10 cents at a yard sale.
