I use lead for 9, .40 and .45 so I'm not sure if this will be any help. Also, I use N320, never have tried BE as it does smoke a bit with cast lead bullets. Perhaps you may find it useful if you ever decide to switch components/powder. I used to use MG 147s for 9mm, but its gotten too expensive. I'd rather deal with the added clean up caused by lead than spend more money.
180 grn. LFP, 3.6grn. VV N320, 1.130 (or so ) OAL. 144 PF
180 grn. LFP, 4.3grn. VV N320, 1.130 OAL. 169 PF
200 grn. LRN, 3.2grn. VVN320, 1.135 OAL. 151 PF
200 grn. LRN, 3.8grn. VVN320, 1.135 OAL. 169 PF
The above loads work well in my M&P, don't know how they'll function in your gun. All were chronoed out of my M&P 5". Even the major PF loads had a lot less snap than factory 155grn. ammo. The last load listed had a single digit SD. Always be careful when reloading, but even more so when using the heavier .40 S&W bullets combined with relatively fast powders.
The minor PF loads are really soft, especially the 200 grn. load. Almost seemed softer than my 147 9mm load.
