I reload for 30/30, .270, 44 mag and .243 plus cast bullets for the 30/30 and 44 and the .50 m/l and 44 navy m/l. If you have the time, casting can save you a lot, but it takes a lot of time and patience to get the hang of it. I wouldnt say that you will save much money on reloading for the mainstreamrifles (30/30, .06 etc.) but for the not so run of the mill guns you can save a ton. Like I picked up a couple of boxes of 30/30 the other day for $7 a box. Its pretty tough to reload for much cheaper than that. I can say though, that I can shoot a lot more for what I used to spend on 100 rounds in the years past. Once you have your brass bought and a can of powder and primers you can really load a lot of rounds for pretty reasonable. Sorry if I sound like I am going back and forth here, its just that once you get your initial investment bought and paid for, reloading isnt all that expensive. Its also very addicting.
