Squeezebores are counter-productive in space. The purpose of a squeezebore is to reduce aerodynamic drag by crushing the sealing flange around a high-density penetrator core. The reason for a high-density penetrator core is obvious--hit a smaller area with more mass at a higher velocity to improve armor penetration. However, in vaccuum there's no aerodynamic drag, so you might was well use an APCR round--armor piercing composite rigid. APCR is like squeezebore ammo that's not squeezed or ADPS with a non-discarding sabot. In space, there's no loss of penetration, range, accuracy, or anything else from keeping the sealing flange.
