I'm looking for another good powder to load up some 40 S&W. I'm using some SR4756 right now and it seems to be okay. I have to keep it on the upper end of recommended loads to cycle my G23 without problems. I'll be loading 180 gr. bullets. What is your favorite?

HS-6. My favorite pistol powder for everything. Great mid load for 357mag, 44mag loads, top performance 38spl loads, perfect for 40, 45ACP, and 357sig. Its a do it all powder. meters excellent.

My standard powder I use is win 231/Hodgdon HP38, not loaded real hot. I got some AutoComp by winchester some time back, which is a little better suited for the 40 then 231 is, but never got to shoot off the rounds I loaded yet. Silhouette from Ramshot is supposed to be another good one for the higher pressure rounds, its basically the same as the old WAP, just with flash suppressant.

I normally use Win AutoComp. HS-6 is also a good choice.

Blue Dot is my first choice.

I like UNIQUE!!

You know when I was a quest to find a good load for 40S&W, unique actually shot better than the rest. And also wasn't real dirty like it is in the 44mag and other reduced pressures. Only thing is the metering of flake powder.

I use Unique in 9mm, 40 S&W, and 357 Mag. I have never considered it "dirty"; especially when compared to Bullseye. I've never felt that my loads showed inconsistancy from metering through my progressive press. Maybe I'm just lucky.
GOOD LUCK and GOOD SHOOTING!!!

Its fairly well known that unique is the dirtiest shotgun powder of them all. At least in the shooting world. Have you ever tried anything else? Or just unique?

Unique was the 1st powder I tried and I didn't get good groups with it at all. I found it was pretty dirty, but I guess most handgun / shot gun powders are. I hope to check out the HS-6 mentioned when I get time. I can't do it at work, most sites that have anything to do with guns are blocked. Thanks for the replies.
