Tank projectiles doing Mach 5, sure. A Rheinmetall 120mm smoothbore like those used on the Abrams or a Leopard 2 can hit 1,580-1,750 mps pretty reliably, as I understand (depending mostly on the round being used, I suppose), which is Mach 4.6-5.1 at sea level. I don't know what kind of muzzle velocities you get out of the L30s you guys use, but I imagine it's in the same ballpark.
