i reload for a bunch of different pistol and rifle cartridges so , overall it saves me a ton of money to reinvest in more ammo

. However, if all i shot was 9mm and wasn't going to reload for anything else i would just buy ammo at case type volume. reloads cost approx $150/k, Ammomasters sells reloaded ammo for $177/k. for the $30-40/k i save i now don't have to scrounge and clean brass(1 hr/k) or spend time at the press 2-3hrs/k on my 550). Then throw on the cost of a progressive setup (close to $300 for a Lee, $500+ for blue or green). Again, this is if you only shoot 9 and have no interest in reloading other calibers. If you find yourself wanting to reload multiple calibers then definitely get into reloading, lots of satisfaction in feeding the pigs with your own handiwork.
