I shoot IDPA and Bulleye matches, I can easily go 1000 rounds of .45 ACP / month. I can reload a 100 rounds for appox $ 9.50, the 100 round box of Wal-mart Winchester is currently $20.50 here in NC. 50% savings
I also reload my hunting rounds, They normally cost the same or a little more than store stuff but I'm using premium bullets and creating the best possible round for my rifle. You can not beat the feeling of pride when you take a nice buck with a round that you have developed.
Just my .02 worth
