Well, I find it hard to believe that hardly anyone needs 150 grains of powder. That must pack some wallop! I will be hunting elk with 90 grains of 777 this next fall (which is equivalent to 105 gr of pyrodex), and that should be plenty of power. If you shoot the gun at ranges it was intended for, less than about 150 yards, this would still be plenty of power. My own personal limit is 100 yards since I will have to hunt with open sights.

Not preaching, you do what you want, just giving you my 2 cents.

By the way, you probably already know this, but in case there are any newbies that are reading this, never use 150 grains of loose 777 powder, only use 3 - 50 gr pellets. Max on powder would be about 120 grains (equivalent to 150 gr pyrodex).
