I cast because I can't afford not to, jacketed bullets cost way too much for me to shoot, but I only shoot 2000 rds a year. The one thing I do know is that casting takes time. I loaded up 350 45 ACP rounds this weekend and it took me about 6 hours total. I started with 0 bullets and the majority of that time was spent casting, lubing, and sizing. I do have to admit that I don't have a huge furnace, but I do use aluminum moulds to speed up the process. The reloading isn't that time consuming, the casting is what slows me down. I don't know what your schedule is like but for me, trying to divide time between work, wife and kids would make 7000 rounds a month darn near impossible to cast. I envy that you can shoot that much.
