I was interested in reloading.. then realized I had nothing to reload, no brass.
So I'm collecting my brass every time I go to the range. I'm filling up a 5 gallon bucket with 9mm, 45 and 5.56. When it is full I'll rethink the reloading idea. That is my approach... but I'll watch this thread for (more) good advice.
If you are just picking up your own brass, then it would be a lot cheaper for you to look on here and pick up the brass when it comes up for sale. All that money you would spend to buy the rounds just to collect the brass, you could spend the money on your reloading kit.
