Federal 115gr +P+ 9BPLE jacketed hollowpoints. Twenty years ago, I thought this stuff was the heat. I could quote you its Marshall & Sanow "One Shot Stop" percentage in my sleep. I had some in my SIG P-228 from a couple boxes that I sourced and treated like it was gold.
I ran some over the chrony today; it averaged 1369fps out of my backup M&P 9. A sub-one-second quarter mile time is ticking right along, I don't care who you are. (That's 478.7 foot-pounds of energy, if you're the sort who puts great stock in that number.)
