Santa01, Reloading for cost saving is based on high volume shooting needs, but reloading as a hobby and enjoyment is a different story. I started out on a single stage setup and it fits my requirements very well. I reload for three reasons 1- Its a hobby and I enjoy reloading , 2 - my bench rest load development enables me to tailor and customize ammo to my needs.. AND.. 3- I reload 9mm handgun as a secondary cost benefit because I have all the equipment, plus get good quality loads and it saves 50% over questionable factory ammo.
If your starting from scratch, with low volume , single caliber I would go for single stage press and equipment. Any reloading is going to consume your time, and most likely not save money if you include you labor cost. However excluding labor you can end up with high quality ammo at close to 50% of factory cost. Once you get moving on a single stage setup you can do about 100 loads an hour working at a nice comfortable pace. Front end costs for a press kit, dies, loading manual and set of calipers would run you about $250.00, supplies save you a LOT of money when bought in bulk, preferably on line. Figure another $250 for supplies (bullets,powder, primer and brass cases) you get multiple uses from the brass if you pick them up after shooting. The front end equipment cost will probably get payed back after about 750-1000 rounds, after that your cost is supplies only and that's where the 50% saving kicks in. Lots of people out on the internet there are going to recommend high end equipment and progressive presses, etc. my thought is the learn on a single stage setup and then make your equipment decisions.
A couple of other forums out there 'Reloaders Nest' and 'Lee Loader' have some good people that will answer questions. Also 'Sniperforums' ,'The High Road' and other shooting forums have reloading sections with a wealth of info. I personally like the Lymans manual for a starter read, its old stuff but covers the reloading process steps in depth. Available on Amazon for $21.
