    You didn't mention the weight of the bullets but as far as diameter goes the .356 is a 9mm bullet by diameter. However, I have on many occasions used my 9mm bullets in my .38/.357 revolvers. I just don't try to push them too hot for accuracy purposes. I keep on the light side. Colonel

    They will work ok, accuracy won't be quite as good as with 357 bullets but it will do no harm.

    When shooting lead bullets, you want them a little larger than groove diameter in order that they will shoot well with little leading problems.

    You can shoot these .356 diameter bullets, but they won't shoot well and there will probably be leading problems.

    As a rule, the place to start with lead bullets is to measure the throats of the cylinger of the gun and buy bullets of that diameter....usually the throats are a thousandth or two larger than groove diameter of the barrel.

    The guys on the following forum are quite helpful if you have questions.

    I hate to disagree with anyone on bullet size but those .356 bullets might work very well. One of my most accurate loads in an old six inch security six was a .356 diameter, Lyman 358156 gas check over 13.5 grains of 2400 in .357 hulls. Shot better than any other load in that gun and no leading. Again, your results may differ. Try 'em out and see what they do. If you get leading after shooting a few, fire a couple jacketed bullets and try another load. I learned long ago that every gun is a law unto itself and what may work in one may not work in another.

    I did find that, in general, TC Contender barrels in .357 are really slick and about impossible to lead.

    Use them all the time, also use jacketed 9mm bullets, work just fine with 2.7 grains of bullseye. No recoil and very accurate. HMB

    A very astute observation on your part. HMB

    .356 diameter bullets are fot 38 Super, 38 Super Comp, etc (semi-auto). They will work in a 38/357 but will probably not be very accurate.

    I used to have a ruger .357 single action, that came with a 9mm cylinder, shot fine.

    I think it was called a .357 convertable, bought it in 1980 I think.

    will work fine if you dont load heavy. They do real good in the 38 mil brass. AS said around 3gr bulleye or near there with what you are using

    Another thought about keeping leading down in the barrel is to keep the speed of the load under 1000fps. Gas checks will help also.

    Accuracy will probably depend more on the barrel than anything. We have a BH here with a 9mm cylinder made around 1981-82 and when 9mm ammo is fired in it, the bullets just barely engage the rifling and occasionally they only show markings on part of the bullet. It might depend on who made the barrel and what method was used. Hammer forged will usually be more consistent in size but the button or mandrel rifled might have some variances as the tool wears down. Either way, I'd think the .356" bullets will work better than a true .355" bullet.
    I've checked Rem and Win 130 FMJ .38 Spl. rounds and the bullets are the same ones used in the .38 super that measure .356".
    Since the bullet is a bit undersize, when you seat the bullet make sure the case has just enough crimp to hold the bullet so they don't slide out during recoil. Might depend on how much the sizer die resizes the brass too as to how much, if any, crimp would be needed.
