Reloading, although associated with shooting, is a hobby in it's self. It is a hobby in which the purpose is to find the most accurate or most velocity that a given rifle/cartridge combo can produce. The combinations are almost limitless with dozens of powders, bullets, and other components available.
Then there is the cost "savings" which is another myth. There is no savings, ammo is just cheaper so you shoot more but you still spends as much or more on ammo. I just loaded up about 400 rounds for the Hyphenated Happening in Washington in a couple of weeks. It cost about $80 for cast bullets, powder, and primers. Factory ammunition at $20 per box would have cost around $400 and would be less accurate. Velocity is of no concern.
We don't reload to have something to shoot, sometimes we shoot to have something to reload.
