6MM Case Length Question

My unfired 6MM BR Lapua brass measures 1.551. Once fired 1.559 and Nosler calls for 1.560. I've been seeing 1.550 on other sites. What should it be?
 
6MM BR Norma is 1.560". I'd find out what your chamber length is and keep the brass trimmed to about 0.015" shorter than the chamber length. The length of your particular chamber is the determining factor, not what a reloading manual shows.
