    does anyone have the load data for 38 special and 357 mag using speer (4203) 140 gr hp with bullseye?

    just the min and max im thinking 3.5 min and 4.3 for the max for the 38 and min 5.7 and 8.0 max for the mag. is that correct

    In my Speer #12 4203s not listed in 38 std loadings & not showing BE as a loading in +p section.

    In 357 Mag start at 6.3 for 1065 fps. -- 7.0 for 1160 fps.

    Primers are CCI550s , COL 1.590"

    I would expect recoil to be a bit snappy on the 7.0 load especially out of a snubbie !!

    Good morning
    My old Speer book #10 shows you are good to go in the 38 Special but the .357 mag tops at 7.8. This is a 30+ year old book & that .2 grain variance may not be a factor today with diffences in gliding material.
    Personaly I would think of the 95% factor. If a 95% load of Bulllseye is to slow shift to Unique .. if a 95 % Unique load is not fast enough go to 2400... Max loads with fast burning powders can get out of hand and there are too many great slower burning powders out there that will safely move that projectile.

    You may also want to check the Hodgdon Powder site at www.hodgson.com This site has been helpful to me on many occasions.

    It does not have to be that exact bullet in the load book or PDF. Start low as you say you are, and work up. :)
