As the wall thickness of the barrels normaly increases from the muzzle to the end there never have been problems because of the powder pressure especially since this pressure decreases on its way to the muzzle.
Rifling onlyt at the muzzle is mostly to be found at pistols with unscrewable barrels to put in a fitting key in order to turn off the barrel. At a pistol with a fixed barrel such grooves make no sense at all.

Thank you so much for this fascinating insight Corrado!!!!!
As someone wo has always studied edged weapons, it is amazing to learn more on the dynamics of these firearms.Your explanations are well worded so that a lay person in this field such as myself can easily follow.
