    Default Best powder for .40 S&W

    I was over at my favorite local gun store a few days ago, and talking to the owner about some of my reloading efforts. I mentioned that I was using Titegroup for reloading .40 S&W, but that even with loads close to the maximum, they bullets still sounded and felt slow. His response was that Titegroup burned too fast to get the best velocity out of the round. He mentioned a powder, but of course I neglected to write it down, and now I cannot remember. So if anyone has some experience with this, I would be interested to hear it - or read it, anyway.

    Thanks.

    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.

    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.

    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?

    .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.
