Hal,
I'm still having trouble with photos, but will do as well as I can. In this type chamber it can be hard to see where the case ends and the lede starts.If the 75 mm case length is correct, it would be a 9.3x75R.This cartridge is in the class of 9.3x72R,and the case head is in the same family.To get 9.3x75R cases you have to trim 9.3x82R cases, which are expensive.It is my opinion that you should just use 9.3x72R ammo and reload the cases.The 3mm difference in case length won't make any practictal difference, but the difference in cost and convience will.
