There's nothing wrong with gun speeds as they are now, even when chasing a fighter. Mjolnir, for example when fighting on a team with me as RM tends to hit more often chasing with 4 600m/s speed, firing at 2.00, more often than I do going head on with 4 750m/s. It's about learning to work with what you have, also if you're so desprate for guns that fire at 700m/s and refire at 4.00 or faster, there's these wonderful civilian guns called an Improved Debilitator , and a Heavy Flashpoint.
