I love this question
Mostly because it reminds us that there are still hard workin kids left in the world and some of them like to shoot. Makes me smile. Any way, yes it will cost you less per round to shoot in the long run. If, when you go the range you shoot 3-4 boxes per session, or would like to, then I would definitely invest in some reloading equipment and, whatever you do, save your brass. Cost to load 100 rounds of 204 is right around $25 if you allready have the brass. You know what it costs to buy 204 locally so you do the comparisson. You do not need the most expensive reloading equipment available to load good accurate rounds. You do need good solid equipment. Some will tell you to buy a new LEE setup, I am gonna tell you not to. For my money good used equipment is the better deal and it is easy to find over the internet with a little guidance. What you need to get going:
Press: Solid single stage like the Rock chucker. Used price $25-$50
Scale: Forget the dippers. Used price $15-30 for a decent one
Powder measure: Rcbs uniflow Hornady $15-$30
Dies get new ones through Midway $25 this month
Reloading manual check for these online as well but new ones are in $20 range and ther is a lot of load info on the internet. You will find that you need other things as you go but this will be enought to get started. I would also get a Hand primer like the one from RCBS but, if your press has the priming arm you don't even need that. The nice thing abou this approach is that you can one or two items a week instead of shelling out a whole lot all at once.
