Bullet making is a broad statement. Do you want to cast, swage or both? Casting is the least expensive. Notice I said "least expensive" not "cheap" To cast, you need a mould, a dipper, some lead, a source of heat and some "boolit loob" If you've done your homework. you might not even need a sizing die. Maybe $100 investment, to start, less if you can score some free stuff.
Swaging on the other hand can be damned expensive. A complete kit of .224 stuff will run you over $1400 US from BT_Sniper. This will include a de-rim die (to make jackets out of .22 RF cases) a "squirt" die, (to swage cores to a given weight) a core seating die, a ogive forming die, a 11 cavity core mould and an auto eject system. These will produce an open point bullet. If you want to make soft point bullets, you will need a point forming die, another $150 or so. Plus the cost of a press suitable for swaging. I use a few of BT's tools and they are first rate! The very best in that price range. You can pay less than that or more, but you won't get any better, IMHO!
You can also buy dedicated swaging equipment, used only for swaging and there, you are limited by the extent of your imagination and the thickness of your wallet. I got into swaging some 40 years ago. My first 2 sets of dies were C-H 2 die sets, in 358" & 429" that I bought from Giovanni's in Toronto for the princely sum of $37.95 ea + 7% tax!!! The same dies today on e-Bay are fetching close to $500 USD. Go to the Castboolits website for a thorough education on the subject then you can make an informed decision.
Good luck and as BT says..........swage on!!
