I have a Berreta 92s that leads up, the bore slugs .356-.357. Typically I shoot powder coated .002 oversize bullets bhn 11-12. I also use NOE expanders that is oversized by .001 when expanding cases. NOE does not have a .359 expander, however they do have a .360 x .356. Would this work to fix my leading issue? I'm afraid of swaging the bullets base down and causing leading. Maybe I'm doing something wrong and jumping the gun.
