I reload for all of the reasons already stated - save $$ (not really cause can shoot more), tweaking different loads with different bullets & powder, and accuracy. And, more importantly, I always have ammo to go to the range & the rise and fall of factory ammo does not affect me. The only factory ammo I buy is 22LR, but sold at least a few bricks recently.
My plinking 223 rounds cost me $0.22 per round, 9mm - $0.11, 38Spl - $0.13, 357 - $0.17, 308 "match" - $0.55.
But, I unfortunately lost all my firearms, ammo, and reloading equipment in a boating accident. Yesterday.
