I just dug out an old notebook from the last time I ran S&B (dark green box, "tactical ammo" FMJBT).
ES = 39
SD = 13.31
FPS Avg = 2731
Granted, this was not 243, this was 6.5 Creed, but the ammo shot "ok". Like I said in my previous reply, it's decent for training, though your groups can get a bit wonky as there are some impacts that make you question things.
