I think someone latched onto the concept of "overmatch" and figured they could apply it across every metric they see with regard to a weapons system.

When thinking about achieving certain muzzle velocities, it makes me wonder if they are looking at existing technology for pressure containment and saying, "5.56 and 7.62 are working at anywhere between 58ksi to 62ksi. In order to have overmatch, let's not just do an increment above that. Let's ramp it up to 75-100ksi...because why not?"

They will need some revolutionary materials science to pull that off and make weight. You don't just step up into 75-100ksi because you feel entitled to "overmatch".

Recoil energy will be off the charts as well. Do they have any competent engineering that they're bouncing these ideas off of before asking for interstellar specs?

Primer retention and integrity will also be an issue, let alone the pressure containment vessel.

These are pressures that would scare off Roy Weatherby, which is saying something.
