I can vouch for the M28's sturdiness.
Back in the mid-70's, I was a young, over-eager new handloader. I got a 6" M28 for the express purpose of using my 'beyond all reason' hot handloads in it. I did not yet own a .44 mag., but determined that I'd have one anyway, just that the hole in the end would be .357!

Never kept up with the number of those sorts of un-wise rounds, but it was in the many hundreds, if not a thousand or more.
It even went through my stages of interest in light bullet/H.V. loads and moved to 'heavy for caliber' cast stuff (I was worshiping at the feet of Elmer Keith about then...) ahead of unhealthy doses of 2400, H110, WW296 and Blue Dot.
The M28, other that becoming a bit smoother, never showed any signs of wear.
(Disclaimer - not advocating doing this to a good revolver, only that in my experience, the M28 withstood the torture well.)
