I' m now quoting from the fifth edition of the Hornady loading manual: .338-06 barrel length 23 1/2, Mauser 1898, 1:9 twist, 250 grain bullets, 59.0 grains Win 760, Muzzle velocity 2,600' /sec

.338 Win Mag: Mod 70-Winchester, 24" barrel,1:10 twist, 73.7 Grains Rl19 with 250 grain bullet, muzzle velocity 2,700' /sec

In my eyes the 100 feet/sec is insignificant. If I can build a one pound lighter rifle on a .338-06 verses a .338 Win Mag, thats significant.

If you choose to live in a world where muzzle velocity is the only criteria, so be it....it' s not the world I live in!!!
