Gear Rifles - design assistance requested

What about a series of spinning disks, probably in pairs, that propel a shot by friction? Each pair spins faster than the one before, to provide the acceleration along the length of the barrel? Somewhat like an automatic pitching machine in a batting cage, but in stages.

Each pair of disks has it's own clock spring. As the round moves down the barrel, it triggers each pair in turn. (This probably works better for a flechette or needle than a spherical shot.) The clock springs are all geared together, however, so that they can be wound from a master crank that is folded into the stock.

The basic mechanism isn't substantially more complicated than a wheel lock. The timing and master crank push this into the realm of unobtainium.
