Re: Best powder for .40 S&W
I settled on 3.8 grains of bullseye behind a 175 grain swc (I think). Nice comfortable round and shooting very accurately out of my 4.25" barrel M&P40. I tried them as hot as 4.4 grain, but that was brutal.

Check out this link:

It covers three brands and all their powders. You can filter it for brand/bullet weight.
Re: Best powder for .40 S&W
I've used Longshot for some loads. IIRC the velocity according to the manual was 1050 - 1100 ft/s at max load. Its got one hell of a kick compared to titegroup or HP-38. Load was somewhere around 7.5 grains so it filled the case pretty well.

Thanks for the input guys. Dave, I appreciate the link, but that is the chart I am using. It will give me data for any powder I care to try, but it doesn't give me recommendations as to which will work the best.
Re: Best powder for .40 S&W

8.9gr of Blue Dot
155gr Magtech JHP
1.125 OAL

Re: Best powder for .40 S&W
Personally, I've had the best results for .40 S&W with IMR 800-X, which is substantially slower burning than bullseye. I use 160 gr TMJ bullets and 7.5 gr 800-X. I started using 7.2 gr, but had some unburnt powder, so I moved up to 7.5 gr and had no problems. I shoot them out of my XD 40 subcompact.
What weight bullets are you using?
Re: Best powder for .40 S&W
.180 gr Cast FP
6.0 - 6.5 Unique
WSP primers
I use this most of the time and its been really good out of both my Steyr M40 and CZ-40B. I've tried Bullseye and 231 but I always go back to Unique for my 40's.

I thought I had put this in, but apparently I didn't. I have a bunch of 200 gr and 180 gr Berry's from Cabela's.
