    I am attempting to load .40 cal S&W 165 grain flat nose/point bullets and cannot find load data in any of my manuals or online regarding Winchester 296.

    Could someone please advise on a source for this information.

    I found this at another forum, how true it is I don't know, but someone will agree or disagree.

    Winchester 296/Hogdon H110 is a powder which cannot and must not be used for light metallic cartridge loads! It is suitable only for full power magnum handgun loads and .30 Carbine loads. W296 is slow burning and needs a case full to ensure complete ignition.

    Great powder for the heaviest .357 Magnum, .41 Magnum and .44 Magnum loads. See if you can trade someone for some HP 38/ W 231, Bulleye or Accurate #2- those are what you need and all are a bit cheaper than W296 so someone may trade.

    I rather doubt you will find any data for W296 powder for use in the 40 S&W. I have only used it in 357 mag. along time ago. Winchester recommends NO reduced loads for use of their 296 powder. To me this means that anything but nearly a full case of powder does not light well and produces incomplete powder burn. So unless you can fill up the case without exceding preasure limits for the firearm it can't be used.

    OOOps if I had known that AR Guy was posting just ahead of me I could have saved myself some typing. Good job AR Guy. Not going to get me to disagree.

    Yep, 296/H110 is used for magnum pistol, 30 carbine and 410 shotshells.
