Realistic gauss weapons deliver payloads at 10 times the speed of conventional weapons, so they cannot be silenced and cannot have their flash hidden (the flash is from the plasma trailing the projectile in an atmosphere). Since they do not use gases for propulsion, they cannot use venting systems to reduce recoil. I would rule that the ammunition listed in High-tech would fragment at the velocities of a gauss weapon, so I would suggest using the superior ammunition in Ultra-Tech.
