[Lonesome in Massachussets]

I doubt that the terminal velocity of a 30.06 slug is 1500 fps, mach 1.5.

What I.m saying is that the bullet is aerodynamically designed to lessen drag . In that matter the terminal velocity will not be reached before the bullet hits the bottom of the canyon . The bullet should impact in about 4 sec. if the canyon is a mile deep . I shoot SHOTGUN target loads that travel at 1400 FPS .
