If it was pointed out that some of the loads put forth in print here considerably exceeded Plus P spec right from the start a lot of ink could have been saved.
While the cylinders were heat treated the frames were relatively soft until a much later date, affecting the K and J frames. Since the OP was asking about a practice load that approximated reasonable pressures, durability of the firearm for extended shooting sessions is the relevant issue, not whether it would blow up immediately upon firing.
The load asked for doesn't require gun strain to achieve.
I agree what you pointed out is worth knowing. In my opinion what I set forth is worth knowing even more than that, and keeps one out of trouble whether a little or a lot of shooting is done.
