....for my .30-.378. I never realized how hard it is to find something that should be somehow more simple. Every trimmer I have looked at is either a whole product but w/o the needed components for this particular case or you have to send in a case and wait 4 months until they send you back a case length guide (Lee), or they don't make the necessary components for a .30-.378. I will greatly appreciate any info on where and how I can purchase a complete system to trim my .30-.378 cases!! Thanks.
