Caseless ammo doesn't have this beneficial property. The gun, therefore, retains a lot of heat and this can, theoretically at least, lead some of the unfired caseless ammo to cook off in the gun. This could be catastrophic.

from my research that issue was solved about 2 years prior to the project being scrubbed. the solution was in three parts IIRC changing the formula for the ammo to be more heat tolerant, improving the barrels heat dissipating capability, and i believe a mechanical safety to prevent a cook-off from chambering more rounds.
