    I’m getting about .358 and I size it to .358. I use it in 9mm and it works great for me.

    mine runs .357+ and does not size in a .358 sizer. I bought an NOE clone to give me bigger boolits.

    It's pretty easily polished out to enlarge the diameter if needed , or powder coating . I size to .357 but they actually come out of the sizing die at .3575 most of the time . Want to try some ?

    I've got a Lee 358-105 SWC coming and I'm hoping for .359" to use in my CZ 75 and also my K-38 Smith. Would then run unsized in the Smith and .358 in the CZ.

    I must be lucky, mine cast out at .360~.3605" I size to .358" and use in my 9mm Luger loads. IMHO it is the ideal cast bullet in that caliber; I've tried many. I never did well with the Lyman 356402, probably because they cast too small...I sold the mold years ago.

    My 6 cavity drops them at 359 - 360 with COWWs + 2% tin. A bit smaller with a softer alloy [ternary with balanced amounts of antimony and tin] at .358 - .359.
