Mine appears to be nearly the least popular choice, but truthfully I only really reload to save money. Sure, once you factor in time it's not as lucrative etc,etc, but as my grandmother always said: "I've got more time on my hands than I do money.".
With range-pickup brass - which the local public range provides a virtually infinite supply of - 9mm Luger using plated (or even FMJ depending on how good of a deal I find) tends to run about about $120 per 1000. That's barely over half what factory rounds cost, and that's the cheapest centerfire round out there. Your savings are even greater on just about everything else. Hopefully as I get into casting my own bullets my costs will come down even further.
The only other real benefit I have is that when I stockpile components rather than ammo, I can load it up and shoot it how I want. If I decide that I want to shoot the .380 this weekend, I can dedicate the components to that. If I want to shoot my .30-30's instead of my .30-06's, I can use the components there too. Whatever catches my fancy I can use up more resources in a more specific manner.
Don't get me wrong there is SOME level of satisfaction to loading my own, but for me by and large it really is just about being able to shoot more rounds for the same amount of money.
