Some of the loads for the 300 are more accurate when loaded down as evidenced in the Nosler book. Why did Remington create three loads for the 300 Ultra Mag that are "loaded down" to 300 Win Mag and .30-06 energies? Because . . . there was a request for that or there was money to be made.
My .338 WM like to be loaded to the nutz but I have not experimented enough with the 300 WM.
