I need to load up some .40 S&W and was looking for opinions on the best powder for 165 grain as well as 180's. One for both would be great but you can never have too much.

I am using FMJ. I am also using single stage press. I may be crazy but I weigh every load.

I ended up loading .40 with HS-6.
In SIGs, with 231 and other really fast powders, the rifling would strip the bullet and cause tumbling.
HS-6 had no problems.
This was with a USPSA major load.
HS-6 here as well
Reloading .40 cal is not a task to be taken lightly. The .40 S&W is a high pressure round and one should be cautious when loading it. Until the OP has a reliable powder measure to throw charges, weighing each will keep him out of harms way.
