Mike Brady test of .458-450-gr soft
BOL = 1.460"
FIV = 1700 - 2700 fps
PIV = 2000 -2600 fps





Mike stopped at 2300 fps with his SAAMI .458 WM load.
.460 WBY shooters ought to keep it down to 2700 fps impact or risk expanding the solid copper base.
.458 WM+ shooters are surely safe at 2500 fps MV.
The North Fork has a slightly shorter BOL than the 450-gr TSX and could be seated less deeply for the same COL.
How does the slickness of the narrow grooves and bands on the North Fork compare to the wider ones on the TSX ?
Probably about the same overall bearing surface and same material bearing.
