It is not souch the diameter of the canon, but how long the barrel would have to be. The forces placed on the payload if shot out of a regular canon, would generally crush most payloads.

They had thought railguns might initially achieve this, but the are worse on payload.

The idea is OK, but the barrel would have to be a couple of KMs long and a steady ramp up of speed is needed.
