You could try 2217. I use it in a 270Win pushing 150LRAB's or 140VLD's. 2217 is a little faster than 2225.
2209 is pretty fast in a 270WSM with a 150 grain "anything" in front of it. I would expect it to pressure spike with a very small increase in charge weight, so be careful approaching max loads.

I've used 2217, 2225 and Retumbo(pretty much 2225). All ok to for me, and compressed too.

2209 would be to fast and running a compressed load of this is asking for trouble.

Before I put a 300WSM barrel on my Kimber 270WSM I had a good recipe that was very very accurate, 140 grain soft point Nosler ballistic tip,68 grains of AR2217 with large magnum primers. My mate also had a 270 WSM and it liked 68.5 grains of AR2217, so this proves every gun has its likes, the reason for changing barrels wasn't accuracy but with the 300WSM I had more optians with projectiles and the thinner factory barrel on the 270WSM heated up to fast, after 2 shots the heat created fliers, the trouble we now have with new guns trying to make them so light it creates other problems as well as having to have a suppressor. I get a hole through a hole with the new 300WSM, the barrel was made by Grant at Trueflite Barrels and made to not have heat problems, sign of a good gunsmith.
