I'm on my 4th firing of this Lapua brass, FL sizing every time and i'm still a ways away from the max headspace on my rifle (2.749). I'd like these to be just short of that max measurement, but my cases average around (2.716) after FL sizing on my 4th firing. Is this normal, figured I'd be trimming by now? In the name of consistency should I just trim these all to my shortest case? Anyone know what the 338LM brass length is new? Could I be losing some major accuracy due to the short brass here?
