I've been doing this for a little under a year, but that sounds about like what i am doing annually. I definitely save $ over factory shells, although not a fortune. I get great prices on components by buying in bulk and like you and many others, enjoy the process of reloading.
Not everything is about the money. If that were the case, we would all stay home, sell our guns, golf clubs, fishing gear, sailboats, etc and plant ourselves in front of the Nanny machine and rot away. I enjoy checking out the recipes, trying different loads and seeing if they help my miserable scores : )
I have to drive 2 hrs to my supplier, but we make it a combo trip by stopping off at Costco,Sportman's Warehouse, have a nice lunch and thus justify in our minds that it didn't cost us a nickel in gas since were driving here anyway : )
