Is this not a non-issue? Nagato's shells use Nagato's body as their frame of reference; they already travel at her exact same speed before the guns are even fired. Their constant forward acceleration would only begin to drop after the shells have cleared their barrel (and are thus no longer "pushed" by Nagato), at which point forward momentum will still have an effect.

The 2600 ft/s (assuming this number does not change for the scaled-down kanmusu version) referenced thus is the shells' "relative speed" (as in: relative to Nagato, and only equal to absolute speed if Nagato is standing still). For a practical example, think of javelin throwers during the Olympics -- they run before throwing in order to build up momentum, in order to increase the spear's kinetic energy and thus their maximum range.

Granted, it's been decades for me as well, so take the above with a grain of salt!
