Removed the gas storage, I figure the mechanical method can work.
Yea, the history is the same since both weapons are essentially debuting at the same time, and have the same social impact on the Lorath.
In the railgun application, the caliber is adjusted by adjusting the distance of the rails from each other. Closer together for smaller rounds, farther apart for larger rounds.

What's the max length of a round?
**Caliber:** The weapon can be adjusted to accept munitions ranging from 4mm to 12mm, with casings ranging from 4mm to 13mm in width, and lengths from 10mm to 80mm
(Added "Overall length from 10mm to 80mm" to the wiki article)
As for the operation of the weapon in regard to caseless rounds, it utilizes a piezoelectric spark to ignite the propellant when it comes down upon it, so yes, it maintains the same mechanical operation.
Over all, the weapon is designed to require little to no additional familiarization when utilizing alternative ammunition. The most adjustment the soldier would have to cope with are range limitations and stopping power.
