.338 Win Mag Powder Overview
In an effort to minimize recoil and noise, these particular bullets are specifically designed for low velocities. Above about 2,200 fps they could foul your barrel. Our load development efforts required us to investigate powder behaviors well above this “speed limit”. We are sharing some of these above-and-beyond data in the Powder Overview Graphs.
We must stress that the Powder Overview Graphs are not loading data in any way, shape, or form. They are simply intended to illustrate patterns and relationships, and, in some cases, are only calculated extrapolations. They are essentially identical to weather forecasts . . . interesting, but too risky a basis for planning next week’s picnic.
