Even more so when there's no air-cooling for the gun.
Not sure how much this limited the 23mm the Soviets test-fired. Probably doesn't matter much with a handgun in a short fight, but anything like a machine-gun or in a long fight is going to face problems.
Open-cycle liquid cooling is the most likely candidate.

In fact, caseless might be at a disadvantage here, because conventional brass cases utilize the case to form a seal in the end of the firing chamber, do they not? They form a new chamber each round; whereas a caseless one has a single chamber, subject to thermal expansion.
The brass case also helps remove heat from the system, always a big plus with firearms.
