Hey Cal
No, the turret type has no real bearing on the ammunition stowage type (unless you know the combinations of turret types to specific hull ammo stowage configurations)
Be this high or low bustled turret, the relevant thing is the hull configuration. A rule of thumb would be late 47degree front (glacis) plate would indicate 'wet' stowage and for cast hulls you would look for the turret type. The upgunned 76mm T23 turrets were on the later M4a3 and M4a1 both of which were wet stowage. The discussion regarding DD M4A1s throws the rulebook out the window a little, as the 75mm gunned turret was used not only on the dry stowage (applique plated) hulls but also on the large hatch cast hulls which normally indicated the later (and therefore 'wet' stowage) version which normally would have been fitted with the T23 turret... BUT I think the DD large hatch could have been dry stowage also... Meaning I've solved nothing here
Here is a late production M4A1 75mm
You can see the subtle cast-in plates as featured in Rick's diagram, more obvious by their shadowed undercut.
