Looking for advice on a 10mm powder for longer barrel pistols (G40)

[Barfly]

I recently acquired a Glock G40 for a hunting sidearm and am looking for recommendations on a slower burning powder that will let me take full advantage of the longer 6" barrel on the Glock 40. Any thoughts? I have some AA#2 and AA#9, but I think they will burn to quick to actually gain anything from the longer barrel.
Thanks in advance.

AA#9 is what I worked up With FishFace (Dave) in the old SGN Days.
He had a 7" and we got the best velocity and accuracy out of it

I was definitely going to try some loads with the #9 i have leftover from my .44 mag loading. I was just looking to see if any other powders might give me more of a velocity boost with the longer barrel.

IMO - - -> Between the 20 and the 40 you're talking less than 1.5 inches of bbl.
Just wondering if you can optimize powder for velocity . . . and if so . . . what velocity. Guessing <25fps.
My OEM Glock 6" "hunting" bbl only gained me another 25fps over the origional Glock 20 bbl. This,using a Double Tap 200gr WFNGC (hardcast) load.
I continue to use it for two debateable reasons. Less "felt" muzzle rise and quicker back on target,especially moving target. And hunting the larger boar hogs in thick cover the 25fps gives me extra energy delivered to target. And I feel that I need all I can get. --- SAWMAN
