    How tight should a. 358 lswc fit in the cylinder throat of a revolver? I'm able to push a hornady xtp through with a pencil nice and easy .

    With the lead bullet, it took a More force with a wood dowl and a tap with a hammer. I measured the bullet after and it measured like . 0005 smaller than before it went in and looked fine.

    The cylinder throats on my new 4" korth seem like they are on the little bit tighter size.

    I think your're good, how does it shoot? My revolvers shoot good, I've never measured the throats, npot going to. I have owned 2 revolvers that didn't shoot well and leaded like crazy. A .45 and a .44, both had OVERSIZED throats. I don't worry about it if they shoot well. I have Hornady lead SWC's, .357", cast bullets that measure .358 and .359. The .357 dia shoot ok except my 642 pulls the bullets. Gonna try gov. brass, it's thicker, should hold the bullets tighter. .0005" darn sure wouldn't worry me.

    It depends on the firearm. I've found that .358 works in all the 38 spcl. and 357 mag. I've tried.
    some revolvers need to be "throated" have the throats honed larger to allow better accuracy by allowing a larger diameter bullet to enter the chamber and fill the bore completely.
