Like I said, no it is not possible because the bullet is faster than the cycle time of the action. By the time the bolt went back, ejected the shell, picked up another and fired it the first bullet would already be out of the barrel. Even if it was a full auto and you didn't have to pull the trigger it still wouldn't happen.

A 500 fps projectile will cover 6000 inches in a second, which means it will leave a 20 inch barrel in .0033 seconds. A fully auto 10/22 has a cycle rate around 1200 fps. This means it will fire a round every .333 seconds. So a 500 fps round would travel nearly 2000 inches, or over 160 feet by the time the second round was fired.

And if I did my math correctly (which I may not have, I suck at math) I find the 1800 fps round taking 140 some yards to overtake the 500 fps bullet. At that distance the trajectory between the two will be so huge there is no way either of these bullets would ever touch each other. Let alone hit each other in the barrel.

And this is with a full auto firing 1200 rounds a minute, doing it by hand I bet you would get off maybe 2 or 3 rounds in a second, if you were really good. Probably closer to 1 and half.
