I love reloading, too...but not the mass production stuff. Maybe someday I'll shoot a lot of pistol ammo, just to get a little better at it, but I doubt I'll ever compete or anything like that, so a thousand rounds will last me for years.
It's cool that you got a great deal on a volume of powder that suits your needs, though. It'll keep you happy reloading all winter and then you can shoot all summer! BOOM!
I wouldn't call reloading fun. I would call it, relaxing. Interesting / enjoyable in terms of dial up or tweaking my loads. What I'm able to do after reloading = FUN
