[QUOTE="Chas1, post: 2114609, member: 15738"] All fired not resized, Sierra 150gr FMJBT, don't measure COAL instead measure to ogive when seating and measures 2.632 (.011 of lands). I'm leaning towards 49.0grs probably isn't enough. I'm also thinking cases at -.017 may have been form early load development when I started out at 45, 46 and 47grs so you could be right on not enough pressure...and so the reverse , they shrink.
