Something I should have added. You may find that the 9,3x72R ammo these days has a rim that is too thick for your chamber. So the case, once it's been through a FL die, will go all the way into the chamber but not the last little bit. If that's the problem, you'll need to either turn down the case rim or deepen the gun's extractor recess. I'd suggest the former but you'll need to turn it down from the front so as not to weaken the case head. You'll also need to make up a spiggott to fit the primer pocket and support the case. At least, that's how my gunsmith went about it, should that prove to be the same problem with your rifle.
