My 'issue' SD ammo is 125 grain, but I feel that a 147 grain round still has the velocity plus a little mass and I'd rather go that way than using lighter bullets. I feel that a 115 gr can do a great job, but my preferences just go in the other direction.
I'll take any of the three.
I'm pushing this theory with some experiments with 9mm bullets heavier than 147 gr. So far lack of reloading data limits me to not so great velocities, so it's still just a theory.
