Bullet's base swaging

Soliciting information and opinions on the title and description of the topic.

I know without a doubt that avoiding swaging the base of projectile is quite important for loading ammo for semi-auto pistols.  However loading for revolver is a new game for me.  I am not sure if issue has same importance, due to the existence of the gap between cylinder and barrel.
