Well, some people say that reloading will save you money...and it might if you shoot something rare or exotic, but any savings are going to be long term. To the effect of saying "I spent X thousand dollars on ammunition components this year, and I saved Y hundred compared to buying factory ammo."
Unless you do it like me, where I bought one bulk pack of 9mm and a few utility boxes to hold a few hundred spent cases and that's all the factory ammo I will ever buy if I can get away with it. After that's gone I will only shoot what I reload and can fit in those utility boxes, and I only reload a hundred or so every few months. That's how I save money, by forcing myself to not splurge on bulk ammo. Otherwise I'd probably hit the range every weekend and buy a few hundred.
I for one find reloading to be rather relaxing, so there's that benefit.
The real benefit of reloading is quality, fine tuning your ammo to your specific needs, and freedom from the ebb and flow of the market. If you have a thousand dollars during an ammo drought you might not be able to buy any, but if you have that same money invested in components you can at least make a few batches of a few hundred each. Plus the components are probably going to be quite usable for a long time. If previous stock is any indication I'd estimate a good fifty year lifespan on properly stored powder and primers, the brass and projectiles are likely going to remain viable for a few generations. Not really going to lose value.
Look at where the market is going these days, ammo is getting scarce up here and down in the states it seems lucky if you find two boxes of the "military" calibers to rub together. Yet there are reloaders who shoot thousands of rounds a year and can easily continue through months of short supply.
