He never said you could get a 180 357 at that velocity, speer #14 110hr 357 1693fps. I disagree with his statement. a 10 mm in a little bit more powerful it's just not enough I think to make a big differenceI would just be very interested as to how I can safely get a 180 grain bullet moving 1500-1700 FPS out of a 6” .357. He must clearly know something I don’t.
