To what pressure you load & whether you anneal the shoulder neck area, will be a factor. The more you push the shoulder back the more you are working the brass & the shorter the brass life will be.
I'll expect 7 firings, give or take 3 firings, depending on loading practices. Some real tight chambering have done considerably better by some.
