I have had a difficult time seating these bullets in 9mm cases. And they didn\’t feed that well in my wife\’s Sig. Then it dawned on me. I shoot 9mm bullets nicely through my Ruger Blackhawk .357/9mm convertible barrel. So I loaded up 18 rounds in .357 cases with 8 gr Unique. At 25 yards off hand they produced a nice 3 inch group. These are great!
