My choice - -
1. First and foremost - -
158 LSWCHP +P - - Remington by preference, otherwise Winchester.
2. If I couldn't locate #1 choice, then the Speer 135 gr. GDHP +P. (Hard to locate in my area.)
3. The Remington 158 gr LSWC +P, NON-HP.
I have provided #1 to my wife, both sons, ex-wife, and myownself. It expands when fired from a 2", and works fine in 3, 4, and 6 inch revolvers. It stays in my bedside model 10 and is in my Colt Agent in my pocket as I type this. I also keep it in the first four chambers of my 3" model 65. It is too brisk for routine practice in alloy frame snubs, but you could fire a cylinderful once a year from now on.
Reason? Over the years, I've probably examined 20 to 30 examples of #1 at Dallas Medical Examiner's office. You know where the ME gets these? At autopsy, usually. I've also read the reports concerning another 50 or so, used in NON fatal shootings. Those were removed during surgery, which indicates the recipients had to go to TO THE HOSPITAL. Excellent sectional density with adequate velocity. They go deep and do significant damage. These are not magic bullets, but they work quite well. They are the standard that the 147 gr. 9mm loads strive to attain.
Best,
Johnny
