There are many opinions on reloading for 9 mm and mine is just one of them. I started with a single stage press and reloaded all of my centre fire pistol calibres: 9mm .38SPL/.357, .45ACP, 44-40, .40. I reloaded thousands of rounds on my single stage press, I batched every operation for efficiency and bought supplies in bulk. I could make 9mm for a bit over 12 cents/per. I still have cheap components loaded deep! I ended up with a progressive press and carried on but at a significant volume increase! I like reloading, it is a great way to learn about ammunition and how to optimise it for your guns and purposes. I like the self sufficiency of heading to the basement to make up 500 rounds for a trip to the club. Have I saved money over the long haul? Likely not given the investment in supplies, equipment and sundries. I have shot WAY more because I reload instead of purchase factory ammo.
Reloading is fun and an essential activity in my shooting sports hobby!
