Todd, it's important to remember that 'ol Jack load of 62gr H4831 was with WINCHESTER brass.
Winchester brass is the thinnest, and provided the largest internal volume. If you switch brass, this load needs to be reduced. In addition Jack's load was probably a little on the hot side. If I had to guess, I'd say it's around 70k psi, which is above modern standards.
