revolving carbine

ive been thinking of doing something like this for a while now, technically any rimmed cartrige can be made into a revolver... so why not a revolver in .303?

this revolving carbine is chambered in .303 british, it has a four round cylender loaded and unlaoded through the silver cutout behind the cylender, 14" barrel and a top 1913 picatinny rail

the only restraint of this gun is that it must use special shortened projectiles to maintain optimum velocities, or reduced loads if using regular projectiles (because the projectile must be seated further back into the case)
