    "Shotshell Reloading Practices and Pressures"

    Another look back, this time at the challenges faced by shotshell reloaders of the 1960's:

    Some of the questions faced then are quite familiar - even today.

    If the velocities seem mentioned seem low, it is due to chronographing at 10 feet. Today the standard for shotshell velocity is 3 ft. Even todays 3 ft. instrumental velocity is down approximately 100 fps from the actual muzzle velocity with small shot.

    Crusher lengths were always measured on a calibrated height gauge not with calipers.

    Well I'd like to see something like this using the .410. Meanwhile, I found this article on .45 Colt shotshell pressures:
