    WST Data for .38/.357

    Hello to all,

    I got given a large jug of WST from a good friends father, it is still sealed.

    I had a bit of a look in my current reloading manuals and very little is available for .38 spec/ .357Mag.

    I was informed by my mates father that he used WST very successful for many years in his .38spec. Unable to get any data from him unfortunately, the reason for selling or giving away his guns and related paraphernalia is due to the onset of Alzheimer's.

    Anyone have some good loads using WST for mainly .38 Spec for paper punching?

    Its a fast burning powder between Bullseye and Winchester 231. You may have to work up your own loads accordingly.

    I had the same problem and have been sucessful in resolving it to my satisfation. I have been using the following data. first let me say that WST seams to be about like 231 and when it dout I have used that data. So far I have been using the following data in my guns with reasonable resultys:
    38 Spl. 125gr cast bullet 4.5 gr WST
    148 and 150 gr bullet 3.5 to 4 gr WST
    158 gr 3.5 to 3.8 gr WST
    I have also used it in 9mm Luger, 45 ACP and 45 Colt.
    I usr 4.5 gr and a 124 gr in the 9mm, 4.5 to 4.8 gr in the 45ACP and 6 gr with a 250 gr in the 45 Colt. All loads seam to be safe and I have fired several hundred of each in several different guns with good results

    in my internet searching have not found any reliable data for 357 and WST

    several loads for 38 special and some for 38 special + P loads

    W231 and WST are close but data is not interchangable
    pressures are higher for WST using less

    I did find a copy of Winchester free reloading catalog

    My .38 spl load is 158 grain SWC with 3.5 grains WST. Love it.
