    Spent a fair bit of time to get to that 13.5 gr 2400 load, then I read it was Elmer's and Skelton's load ,could have saved a lot of time but it wouldn't have been half the fun.

    Plus One - I recommend 14 grs 2400, and I have used 15 grs - in the old days...

    One of the most endearing sights in the world is the vision of a naked good-looking woman leaving the bedroom to make breakfast. Bolivar Shagnasty (I believe that Lazarus Long also said it, but I can't find any record of it.)

    Brewer, for a midrange load in your magnum - try this. Go to your handloading manual and locate data for 38 Special with jacketed bullets. Locate the chart with your bullet weight, find your powder of choice and use the maximum powder charge for the 38 Special in your 357 Magnum. The longer case length of the 357, along with the greater strength of the firearm, will readily accept this load level. The bullet velocity will be lower than what the chart shows for the 38 Special caliber due to the longer case length of the magnum brass. This approach should get you very close to your goal of a safe reduced load in the 357 Magnum.

    That bullet has been around for a very long time and was the "go to" bullet for the 357 Magnum round for several generations.

    Powder charges of 13.5 to 14.5 of 2400 is what will do it these days. In earlier times up to 15.5 grains for the solid point and 16.0 grains for the HP version were used. Don't do that today.

    If you are going to shoot the 357 or 44 Magnum rounds, 2400 or AA9 are the powders of choice.
    Disclaimer: The above is not holy writ. It is just my opinion based on my experience and knowledge. Your mileage may vary.

    Herco worked for me @ 1100+ fps for that bullet but preference was for 2400. 231 or HP38 will give good mid-range performance.
