Question

What is the largest calibre that modern technology could give a machine-gun mechanism and rate of fire?

Short answer

Probably about 76 mm, although such a system would be very heavy.

Notes

A 76 mm weapon could probably retain a modern machine-gun rate of fire. That is a tentative upper-calibre estimate. A working system would be very heavy, and no existing installation is identified.
