I don’t shoot as much as @Effendi , probably only around 10k/yr, but like him I look for deals to cut down on costs. I cranked out 1000 rds of 9mm yesterday. Took about five hours on a Dillon 550 but I’m a little slower than most. No case feeder, no bullet feeder, and I spot check the powder charge and OAL every 100 rounds. I estimate the cost was around $.125/round using range pick up brass. Most of the cost was bullets - about $.07 ea for 135 gr. Blue Bullets when purchased in bulk. Federal small pistol primers are $44 for 1000, so $.044 ea. A 8 lb. jug of Titegroup was $140, figure another $.01 for a 3.3 gr. charge. This doesn’t include the cost of the press or my time. For comparison, Blazer and Federal 9mm are around $.16/round when purchased in bulk. It’s cost-effective to reload 9mm if you shoot a lot, have ready access to brass, have free time, and can afford the initial $1000 investment in equipment. Reloading other calibers is far more cost-effective. For example, I estimate my cost to reload .40 S&W at around $.135/ea using 180 gr Blue Bullets and 4.2 gr Titegroup, which is about half the cost of Federal or Blazer in bulk.
