Sorry to be late to the dance, but the factory ammo is "optimized", so to speak, using the slowest powders, so as to utilize the greater case capacity, to achieve the highest velocity. It's like buying ammo for a great deal of money that delivers on the idea that it is "the finest", which equates to the highest velocity in this instance. You certainly cannot argue with bullet choices and performance on game of the ammo.
