    Should be easy, 358156 .357 boolits

    Hi guys,

    Can anyone supply me with about 30 358156 boolits, sized and gaschecked at about .358?

    I don't care if it is a genuine Lyman or one of our many clones. I am having difficulty getting consistent results with my plainbase clone, just want to see if a GC makes a difference in my particular gun.

    I assume boolits already lubesized and gaschecked would be the simplest, but for that matter I could lube and size them if someone has them just as cast, but then I would also need the gaschecks, as I don't use them in this caliber.

    I HATE auto-correct

    Happiness is a Warm GUN & more ammo to shoot in it.

    My Experience and My Opinion, are just that, Mine.

    If your cylinder throats are too small GC won't help.

    Are you having trouble with just the 156 boolits ??

    & yes too small throats will cause problems with any boolit.

    The 358156 likes the gas !

    I`ve had my throats reamed to .0005 over bore & the 358156 degrades the lower you go under 1k fps.

    I have gc`ed hp, plain based hp. & solids in both .

    The hp`s are more tolerable to down loads , the pob is futher back from the oglive.

    The 357446 is even more intolerable but has a wider meplat & performs wonderfully on medium sized to large (180#) deer.

    Ifin you want a lead boolit for plinking & down loading look at the lee 125,158 rnfp , I like the 158 as the 158 gr rnfp going slow & the 175-185 going 1k fps hit very close for me.

    This has been my exp with 4 GP100s & 1 sp101.

    Again you need to slug the bore & measure the throats ,I use a j word bullet for a gage & a decent 0-1" micrometer.

    1 thing to mention if you`ve been shooting 38s in a 357mag make certain the crude ring is cleaned out as it`ll act like a down sizer ring on the rear of the boolit.
