I guess the best answer is "it depends". How much sizing you do, how much pressure must the brass endure, how well the brass fits the chamber, the type cartridge, quality of the brass, etc.
For my 7x57 I have 10 loads on one lot and it shows no signs of quitting. Same for my bolt action '06. For my M1 and M1a I expect to get 4 loads and maybe 5. for high pressure loads in Dad's .338 3 loads if heavy loads and full length sized and even then I'm worried about head separation. My Krag has such a huge chamber only 2 loads if full length sized. Much better with neck sizing. The '06 has such a tight chamber that a full length die is just about the same as neck sizing.
So give us some details of what you have and what you want to achieve.
