When I first started reloading I was pretty heavy into bullseye pistol shooting and kept at it for a long time. The cost savings of my reloads over factory match ammo was tremendous. It allowed me to amortize my equipment costs pretty quickly, even when I kept upgrading. Even when I had a demanding job with long hours, I still found time to reload. Like goodcat says, it is nice to be able to tailor loads for different guns and purposes. I can't say that I have ever enjoyed the process of reloading, but there is a satisfaction in shooting the ammo I have created, especially when I won a match.
Being a numbers guy, I cannot justify the means by savings alone. If I load 150 an hour on my turret press, that's paying myself $15/hr. I cannot justify my time. But man does it feel good to make and shoot your own ammunition!! It's not about the savings. Time is money. It's about accomplishing something, especially when you win something as you mentioned!! I won a small steel match last week using my 147gr reloads in production class. Only six competitors in production anyways, but man does that steel ring especially well when you loaded your own. I like looking at my the cartridges as I load them and think, "What will you be doing for me, little guy?".
