I'll be the dissenting voice I guess.... reloading for pistol sucks. Do it only if you have to.
After tumbling your brass, you have to inspect every piece for cracks. Since the cleaning media likes to jam up the casefeed tube (at least on my Dillon 650), you also have to ensure that the flash holes don't have a piece of media jammed in there. I don't know how fast other people do this, but it takes me a couple of hours per thousand rounds. After that mind numbing task is done, you get to move onto actually making ammunition. 500 rounds per hour. 1000 rounds per hour. It doesn't matter. Cranking that handle over and over again for an hour or two is not enjoyable. Monotony sounds like a small price to pay for cheap ammo, but it really isn't because reloading ammo isn't cheap anyway. Buy 5,000 primers. Buy 2,000 bullets. It not only adds up, but you have to buy the components in volume to start realizing a decent savings. Even if you're the one guy in a thousand that has a free source for obtaining wheel weights, you still have to collect it, clean it, melt it, and then cast every single one of those damn bullets. Naturally this requires more equipment and again more time. It quickly starts to feel like two hours of shooting means spending six hours reloading.
The pro's? Over the long haul you will recoup your investment costs and eventually start turning a savings. You can make hot loads, soft loads, and loads that you just can't buy off the shelf (a hotloaded wad cutter!). Economies of scale force you to stockpile components so you'll still be able to make ammo and go shooting even when your wallet is empty.
Why do I reload for pistol? Because I have a ton of money invested in reloading equipment and I need to recoup my investment. Also, the wife doesn't seem to notice when I drop a hundred here and a hundred-fifty there buying components whereas if I spent $300 on BDX ammo every couple of weeks, she'd go ballistic.
