I am waiting for the other shoe to drop. There is something that isn't being said or isn't known.

I have the same gun only in 38spl. I have run loads that are only found in older manuals that push the performance of that caliber to the maximum and then some.

In order to blow a gun up, pressure has to develop to over twice what the caliber is designed for. SAAMI, which Smith & Wesson follows to a tee, requires that for a firearm.

So, pop, BAAAAANNNNGGGG, or something else needs to be found out.
