I haven't experimented with reduced loads in many years, but I do remember in an old Lyman manual of the day that if it is a bottlenecked case which headspaces on the shoulder, then you will slowly begin to see the shoulder recede, which can then lead to case head separation when you use reduced pressure loads.

Consequently, I reserved such reduced loadings to rimmed cases. Cast bullets in 7.62x54r rounds were a nice low recoil, low muzzle blast, way to spend an afternoon plinking at cans.

FWIW.
