When I reload parallel side pistol cartridges, the "full" die set includes a powder through expanding die which expands the case mouth as it receives the powder charge.
However, full "rifle" die sets don't include a powder drop die. You need to purchase rifle charging dies separately, and only long and short case dies are available, which indicates there is no mouth flaring operation going on, otherwise there would be charging dies for each bullet diameter.
In my reading on other forums, it sounds like case expanding on rifle dies takes place in the full length resizing/decapping die. If that is possible, why isn't it done that way on pistol cases also?
