    no grain is the weight of the bullet,powder is also measured in grains but you only use around 4.8 to 5.2 grains of powder in a cartridge but it varys according to cartridge being loaded bullet type bullet weight and type of powder used

    No, the "grain" weight listed is the weight of the bullet. Most manufacturers don't list the powder charge weight.

    Common bullet weights for .38 / .357 are 110gr, 125gr, 130gr, 158gr & a few other misc's.

    Recoil is directly related to bullet energy.

    The 158gr .38 Special is probably going around 850fps, for a little over 250 ft/lb of energy.

    The 130gr .357 Mag load is probably going between 1400 and 1700 fps - could be as much as 885 ft/lb of energy on the high end of that range.
    Lighter bullet, but going significantly faster = more energy.

    Now remember, energy is not the end-all measurement of bullet performance, since it doesn't take penetration or expansion into account.

    I prefer the lighter (110-125gr) .357 Magnum loadings.

    Hope that helps.

    Peace,

    It's actually one of those weights/measurements adopted from the British.
    grain or gr=0.037 dram, 0.002286 ounce, 0.0648 gram

    Recoil is directly related to bullet energy.

    Yes...another way to think of it is 7000 grains per pound.

    The powder charge may be different depending on the powder uses as well. 4.8 Grains of one type of powder, may produce the same balistics as 5.1 grains of another type/brand of powder.
