I just started using the Hornady headspace gauge that attaches to a vernier caliper in order to get minimally FL resized cases for my M1A in .308. I have determined that the proper resized case measurement from the base to the datum point is 3.635". Unfortunately, in order get that measurement after resizing, I need to adjust the die down .016" (as measured with a finger gauge) more than there is room, as the die bottoms out against the shellholder .016" short of where it needs to be.
Has anyone else had this problem? I am guessing the FL die needs to be shortened a tad, unless I am doing something wrong. I have tried this with both Redding and Hornady FL dies and encountered the same problem.
I'll add that I have also encountered a problem seating .110gr. VMax bullets in a Redding seating die as the seating stem isn't long enough. Arghh.
