As above my cartridge Oal varies by up to 0.005 and length too give around 0.003 to 0.004. You can sort Theo give measured ones out to be pretty close but the COAL always varies.
With regard to tension. Many firings on brass? Annealed?
As above..never used a crimp though this could help

Brass is on about its 6th firing. Was annealed the home made way with a battery drill and blow torch at home after its 4th firing.
