Home Forums Hunting & Shooting Express Rifles and Big Bores Only The great 458 Winchester. Everyone should own one at least once

1400 fps to 2000 fps makes the 525-grainer very friendly to shooter's shoulder.







5 other bullets were tested with same powder charge, shown below alongside the 525-gr FNGC, all with 23" McGowen barrel:





Looking back at the 500-ish-grain Government bullet, and making allowance for temperature differences,
shortening COL from 3.500" to 3.375" with same powder charge results in about 30 fps MV increase.
Similar effects should be considered with the other cast bullets.
Longer COL will require more powder to equal the shorter COL velocity.
