It seems intuitive to me that...

Well, the expanding gasses are all behind the bullet, so the bullet is riding the edge of the gasses. So the first thing that's going to come into contact with your finger is the bullet. It's traveling at quite a velocity, and is quite a bit harder than your finger, so it seems that the bullet would (somewhat explosively) push your finger, or at least little bits of it, forward and out of the barrel. The bullet exits with reduced velocity because of the friction it overcame, and the gasses exit the barrel before the pressures get very high.

Where am I going wrong? Would the bullet not push the finger out? Would the time it takes to push the finger out delay the expansion of the gas by a tiny fraction of a second, but enough time to cause a rupture maybe?
