If it’s a flat nose there may still be no point . That was hornadys clever/lame Flex Tip lever evolution add...”all other lever loads are pointless!”You can make due with any brass, primer and powder , but it's the bullet that does the work. It also provides flexibility and functionality. Obviously all components are needed, but without the bullet...what's the point?
I lean towards brass being the most important component in general, so if fireforming is how to get the most important component of a cartridge, the components used to form that case are all of greater importance than the same component used in the final cartridge, so... all components are equal, but some components are more equal than others? Metaphysically or something.
