Could one safely fire a .223 Rem/5.56x45mm NATO out of a .222 Remington Magnum chambered rifle? Would it fire form the 5.56 brass into a .222Mag case?

Without looking at the chamber and case dimensions my first impulse is that the necks will be too short to load as .222 magnum cartridges.
I'd probably load fire forming charges without a bullet to experiment. |

Length is 1.85 and a .223 is 1.760. I know you can make regular .222 out of .223 cases (which is a pain in the ass) but I'm not sure you have enough metal to stretch for the magnum.
Do NOT try and fireform a case that is too short for the chamber. The end result is more than likely going to be a split case and the front half stuck in the chamber. I suggest trying .204 cases. 222 magnum is it's parent case if I remember right and the same length. It should be just one pass thru a sizing die and annealing |
