The number of reloads depends heavily on the sizing regimen you use.
Suppose you're not overworking the case by sizing the body down to like new dimensions every firing. Then the effects of fatigue fall mainly on the case neck.
LC brass is usually on the thick side. Loaded rounds typically measure .337" on the neck OD. So a sized neck only needs reducing to .335" or so. If you're using a collet or bushing type size die this is easily achieved.
Now let's suppose you're using an off the shelf Redding FL die like one I have. In order to accommodate all types/thicknesses of brass it has a neck section a good bit smaller than .335". This particular die is on the small side with sized but not expanded brass coming out of the die with .328" necks. So if it's expanded via expander ball or other means to the desired .335" before seating a bullet that's .014" (.007" down, .007" up) of unnecessary cold working the neck material undergoes every loading cycle.
