I am new to reloading, and I understand that one of the possibilities of reloading is to diminish the quantity of powder, so as to reduce the performance of a given cartridge.
Does that mean that for a given bore diameter, the more powerful calibers can always be loaded down to produce the same performances as the less powerful ones ?
For instance, can a 22-250 Rem be loaded down to produce the same ballistics as a .223 or a 22 Hornet ?
Or can a 7 RM be loaded down to the performances of a 7x64 or a 7-08 ?
What are the limits of loading down cartridges ?
