I started to reload 9mm 6 or so years ago, with an old Lee 1000 press, because someone said "your wasting you time, just buy factory".
So I did the cost analyst thing, and my first run came in at $6.73 per 50 way back then. Yes all components have increased over the years, but my last run of 1000, costed out at $8.78 per 50. Time is not included, as that is just an enjoyable part of the process. On cold and miserable days, when going to the range is the last thing on my mind, the press beckons. (It also keeps me out of the wife's hair, which is a benefit to all)
That started me on the slippery slope to reloading 303, 30/30, 38/357, 38 S&W, etc. Do I save money, perhaps not in the long run, but boy do I get to shoot a lot!
Sure I still buy factory for things that I don't shoot that often, like the 7.5 x 55, 7.62 x 54R, 6.5 x 55, 308, and 45.
All in all its just another facet to the sport.
Experiment, ask question, read up on the subject, watch YouTube vids! hey you may even want to start casting your own projectiles?
Enjoy. Cheer.
