� I'm a fan of velocity and I'll generally try to wring the potential out of the cartridges I load for. �
I'm
much more interested in
down-range velocities than I am in muzzle velocities.
Muzzle velocities don't last. The faster a bullet starts, the faster it slows down.
Just for kicks, I just now ran the numbers� for one of my favorite cartridges with the same cartridge, same bullet, same
everything except muzzle velocity and Pmax.
The bullets' BC is 0.473. The two muzzle velcities are 3,850 ft/sec and 3,500 ft/sec.
The difference of 350 ft/sec in muzzle velocities dwindles to 122 ft/sec at 500 yards and to 101 ft/sec at 1,000 yards.
The difference in Pmax is 60,000 lb/sq in. minus 50,000 lb/sq in. = 10,000 lb/sq in.
"Sacrificing" 350 ft/sec at the muzzle doesn't cost me that much out there where the bullets meet prairie dogs and coyotes.
