9x19 in 7,63x25 chamber

A GOOD and SENSIBLE practice is , NEVER fire a round through a gun that it was not chambered for.

There are several factors to consider. Failure due to pressure. Failure due to detonation. Failure due to metalurgy. And failure due to stupidity.

An example: It stands to reason that a 12ga shotgun should take higher pressures than a 20ga shotgun. However, if you fire a 20ga shell in a 12ga it can result in "20-12" detonation. A 20ga fired in a 12ga can and will blow up like a hand grenade. The kenetic energy needs to be tightly contained. If not, it will result in detonation. The same is true in all firearms. The rapid expansion of gases increases dramatically between the cartridge case and the chamber wall. It's like driving a car into a wall at 5 mph which would stop the car. As opposed to driving it 75 mph, the wall fails.

In 40+ years of shooting all types of guns, I have seen some pretty amazing and foolhardy things. I've also seen people with parts of their anatomies damaged and missing, due to "experiments" and negligence with firearms.

My advice is DON'T!!

It could result in having to type with your elbows, and reading with one eye...
