Does anyone load hot 40 S&W for their personal 646?
Ordinarily, I'd assume that any cartridge destined to be shot through a revolver can stand to be near the bleeding edge. However, given that S&W didn't chamber the 646 in 10mm, when it very easily otherwise could have, gives me pause. That they avoided chambering the 646 in 10mm implies that average factory-loaded 10mm power was too much and a brightline not to be crossed.
On the other hand, at the time 10mm was not nearly as popular, chambering the 646 in 10mm would risk cannibalizing some 610 sales, and one of the goals with the 646 was to create a moon-clipped L-frame for competition that could make major (which the 40 did, so no need for 10mm).
