i prefer the 147s because they shoot identically to my competition load and give the smoothest, least snappy, fastest recoverable recoil impulse I have found. Yes, all 9mm is fairly manageable, but I can manage .16-.20sec split times and stay in a vitals zone on a silhouette at 7yd all day with these.
