CZ93X62
Official forum enigma
I have owned at least 15 38 Special and 357 Magnum revolvers over the years, and have likely fired 150K cast bullets through these arms over the past 45 years. both of these numbers estimates are quite conservative. EVERY ONE OF THOSE CASTINGS spec'ed @ .358" diameter. The only .357" bullets these guns have seen wore jackets, and there were at least 25K of those as well. I have yet to cause harm to any of these guns, though one of my Colt Trooper MK IIIs developed a loose extractor star.
