Thread: Shoulder bump question

So I’m wanting to FL size to bump my shoulders back .002” or there abouts from the point where my brass won’t chamber smoothly anymore (Erik Cortina method). But I’ve never found I have an issue rechambering fired brass. I put it to the test today, firing 4 pieces of brass 4 times each. Annealing and neck sizing only between firings. Interestingly the shoulders didn’t move forward at all and after 4 firings the brass chambered as smoothly as virgin brass. Now I’m thinking should I just neck size…
