It is .355. You might be able to load .357. Depends on the gun. The common issue with .357 bullets was it slightly overstretched the case mouth. In some guns rounds would not chamber. The work around that has worked well is simply running .357 bullets through a 9mm bullet sizer. Same can be done with .358 bullets. I was intrigued by the 350 legend. But the reloading difficulties killed it for me. Thought I could simply resize some of my hoard of 223 and use my mountain of 150 grain .358 bullets I got. But the cases are different and resizing the bullets is more work than I want to do. As for Ohio can't help you there.
